An Interclub Racing Dory

Swampscott Dory Dimensions

As the refinement of the Swampscott dory type reached its zenith, the need arose to depart more distinctly from the workboat origins where rowing was as important as sailing and to develop a dory type specifically for sailing in interclub races. And, as John Alden never failed to appreciate the trends of his time, he set Sam Crocker, then in his employ, to work on a sailing dory one-design class in early 1921. The result was a beautifully modeled 21-footer with a marconi rig that carried 350 pounds of inside ballast. William Chamberlain built the first boats (and many of the rest), which were first sailed in 1921 at Marblehead's Eastern Yacht Club. So successful were the boats that other clubs ordered more built, and the Indian class was well on its way. The Indian is built dory-style, with the bottom, stem, transom, and six sawn frames being set up first. After the planking is completed, four pairs of steam-bent frames are set in place between each pair of sawn The round-sided dory...

Rigging a twohanded dinghy

Vago Main Sheet Block

Every dinghy is rigged in a slightly different way and you should familiarize yourself with the manufacturer's instructions for the dinghy you are handling. The rigging sequence shown here is an example of how to rig a typical two-handed dinghy. select a flat location with the dinghy parked securely on its trailer and sufficient space all around. Check for overhead cables and other obstructions. Lay out the mast, boom, and rigging components. The mast may be fitted with a separate wire forestay to attach to the bow on dinghies with roller furling systems the forestay is provided by a luff wire built into the jib. If there is no conventional forestay, attach a rope temporarily. Ensure that each wire is led 1 Prepare the dinghy for rigging on its trailer or dolly, with clearworking space all around. When possible, choose a day with light wind. Two people are needed to rig the boat. In light wind, a small aluminum mast can be lifted to a vertical position by one person. On some dinghies,...

Hull Structure And Planking

The building of big wooden hulls with load-bearing frames reached a stage in development at the end of the sixteenth century in which all structural elements were already present more or less as in nineteenth century ships. So refinements were slow in the seventeenth and eighteenth centuries. Building methods varied from country to country only in the details. All ships, or at least all square rigged sailing ships which were built in European shipyards from Trieste to K nigsberg, were essentially the same from a structural point of view. Eighteenth century English shipbuilding is fairly well documented, first by a number of original contemporary models made by the dockyards which had built the ships. Then there is a considerable amount of modern, high-level, research. What is missing are systematic, detailed works by contemporary writers during the early eighteenth century. These were only produced at the end of that century. Since the plans of Royal Caroline provide many indisputable...

Early Cape Dory offering by way of Allied Boat Co

Trailering Cape Dory Typhoon

George Stadel Cape Dory Yachts 1972-1982 264 sq. ft. portable portable This boat started life as the Allied Boat Company's Greenwich 24 (see page 268), but Allied sold the design and the molds to Cape Dory in 1972, when the company was beginning to add cruising boats (Carl Alberg's CD Typhoon 18 (19) in 1967, Ted Hood's CD 30 in 1971) to its daysailer offerings. Cape Dory modified the hull somewhat, raising the freeboard a bit to get more headroom (which added seven inches to her length on deck and the same amount to her waterline length), moving the head from between the forward V-berths to its own space on Cape Dory 25 Mk I 24' 10 7' 3 3' 0 3,850 1,500

Two Chesapeake Skiffs

Parker Marine Enterprises

Chesapeake Bay sailing crab skiffs can, with little alteration, make fast and able daysailers. These skiffs first appeared on the big estuary during the last years of the nineteenth century. The type perhaps we should say types varied wildly from creek to creek. Depending upon local conditions and prejudices, an observer at the time would have found single- and two-stick rigs, with or without headsails. Deadrise amidships (amount of V to the bottom) ranged from 0 degrees to about 12 degrees. Hulls were double-ended or transom-sterned. In fact, the diversity in skiff design allowed watermen to identify a boat as the product of a particular county, if not a particular builder. In addition to serving as their name suggests, the skiffs earned their keep in general waterfront transportation and by handling odd jobs. Although these boats went extinct half a century ago (at least as working watercraft), many of their characteristics survive in contemporary Chesapeake outboard-powered skiffs....

How Are Catamaran Masts Fixed Down

Catamaran Stays Diagram

Most masts on production multihulls are fixed, non-articulating, aluminum extrusions and are therefore preferred for their reliability. Shroud, forestay and leach tensions are counteracted by the compression of the mast on the central crossbeam, necessitating this critical zone to be one of the strongest structures on a catamaran. Loads are measured in tons. In some recent mishaps, high-strung and under-built America's Cup racing monohulls broke in half because of these massive rig forces. below The absolute best way to attach shrouds to a multihull. Aramid lashings are very strong, extremely reliable and easy to visually inspect. We should also look at rotating masts which, if properly designed, have advantageous applications even on a cruising catamaran. As we have seen, multihull masts must cope with a large range of loads. Since momentary rig forces can be 50 higher than on monohulls, the entire rig and its support system must be stronger. This can either be achieved by beefing up...

Trinidad For Boat Building

Trinidadians have been building boats for years, especially power boats and fishing boats both for export and their own use. Bowen Marine, Formula III and Peake all have a good reputation in the power boat market, including fine cruising boats and some very fancy racing craft that, in the wrong hands, would raise the eyebrows of any customs officer from here to Miami. The sailing yacht market is newer. Soca Sailboats have a factory on the Eastern Main Road in Trinidad where they build Henderson 30 racing boats, as well as occasional custom boats. One of their craft Crash Test Dummies , a Henderson 35, cleaned up in the Caribbean racing circuit for a year or two. Last news was they were trying to sell it and build something even taster. They have an impressive factory with their own heating oven for building carbon fiber masts and they mold their own Samson Boats in San Femando build a variety of custom boats from fishing pirogues to giant cats.

Catamaran vs Monohull

Catamaran Monohull Sailboat

In order for us to appreciate the advantages of a catamaran it is important to be aware of their different attributes as compared to their ballasted counterparts. Although both types of vessels rely on watertight hulls to safely separate seawater from precious cargo on the inside, their stability is achieved via totally different means. Data of a typical 45' monohull will be compared to a 45' cruising catamaran, illustrating the diverse characteristics of both types of boats. Why are multihulls generally faster and do people really get less seasick sailing them In this chapter we objectively investigate advantages of catamarans such as their stable and spacious environment, low draft and the fact that beginner sailors feel more confident. But be aware, not everything is all roses. Although the well-designed and -built cruising multihull provides many rewards in terms of safety and handling, we will also investigate some of their drawbacks. Higher maximum and average speeds are what...

The Age of Exploration Carrack and Caravel

Age Exploration Sailing Improvements

In the early fifteenth century the pace of ship development in the Atlantic tradition began to pick up this was the period with the most intense development of sailing ships. I hinted earlier about the potential for ship growth (in size) and development should the northern clinker and the Mediterranean carvel designs fuse. Such a mixing began with the Crusades. Many northern knights headed for the Holy Land in their double-ended clinker-built ships, taking them into Mediterranean ports en route. Better ships led to increased trade further afield, which contributed to the mixing of ship-building ideas so that, instead of two separate strands, Europe became a melting pot of diverse ideas concerning ship design. One of the first fruits of this melding of ideas, and certainly the best-known and most successful ship of its day, was the carrack. rig sails were good at running before the wind, while the Mediterranean lateen sail permitted tacking and yielded better control. Later carracks...

Cape Dory Yachts decided to start from scratch on a new 25-footer after sales on their existing product, the CD 25, designed by George Stadel (see page 329) began to taper off. They hired Carl Alberg to come up with a bigger, heavier, more powerful boat capable of cruising two in comfort on extended cruises. Alberg eliminated the traditional forward V-berths and put in their place something not often seen in a boat this size a head with vanity, wet and dry hanging lockers, and a really rare feature, a shower. Also included are an L-shaped galley, two settee berths amidships (with one convertible to a double), and a quarter berth to starboard. Headroom is 5' 11 , very good for a boat only 25 feet on deck. A single-cylinder 8-hp Yanmar is standard. Best features In our opinion this boat might come close to the ideal boat for couples who want a cruising...

Catamaran sailing downwind

Jib Sheet Rigging

One of the main principles to bear in mind when sailing a catamaran on a downwind course is that you should never sail directly away from the wind. Instead, you have to sail a zigzag course, known as tacking downwind (see below). Because a catamaran achieves very high speeds on a broad reach-far higher than on a run-it is worthwhile sailing from one broad reach to another and jibing across. Although most monohulls also sail faster on a broad reach than on a run, it is not worth tacking a monohull downwind because the speed gained on the reach is not sufficient to compensate for the extra distance travelled. Provided you remember to keep the wind on the beam and adjust your course accordingly you will keep the boat sailing on the fastest course downwind. scale, it can be seen that there is a greater speed difference between a broad reach and a run (A-B) with the catamaran than with the one-design. scale, it can be seen that there is a greater speed difference between a broad reach and...

Tacking and jibing a catamaran

Sailing Tacking Into The Wind

Catamarans tend to tack and jibe more slowly than monohull dinghies, but provide better stability. This is particularly noticeable when jibing, which is comparatively easy to control. The technique for both maneuvers is very different from a center mainsheet dinghy. In a catamaran, the helmsman should steer into the tack with the rig powered up and the boat sailing at speed. Steer carefully through the tack be aware that slamming the rudders over can make them act as brakes. Both crew should stay on the windward side until the jib has As you start to tack, keep the jib backed in order to help turn the bows, as catamarans are often slow to turn through the wind. Highperformance catamarans with daggerboards can pivot more quickly through the turn. backed. This will help to lift the leeward hull, so that the catamaran pivots on the inside hull. Keep both the mainsheet and jib sheet pulled in tight until the jib starts to back and the bows bear away on the new tack. The helmsman should...

Multihulls Catamarans

Plans Catamarans

Catamarans have a relatively long length along the waterline and no ballast at all, and consequently hold a straight line very well. The pressure on the rudder is relatively low as well, so they are easily steered. They accelerate far faster than monohulls in the puffs, however, which causes dramatic fluctuations in the apparent wind angle. The same is true in the lulls they slow down quickly and the wind swings aft. The principle is as follows when a gust hits a monohull, it causes increased heel and minor acceleration and the apparent wind swings forward only a little. A multihull is unaffected by heel but accelerates quickly the apparent wind angle swings forward markedly. This explains why catamaran sailors have always relied almost exclusively on autopilots. However a windvane system can be useful on extended voyages. Servo-pendulum systems can produce perfect steering on catamarans. The great speed potential allows the pendulum rudder to generate substantial steering force. The...

Sailhandling Monohull vs Multihull

Monohull Multihull

Sailing trim on a catamaran does not differ greatly from that on a monohull, yet to a large extent it will depend on your experience, the actual boat you sail, and your perspective. Since the basic sailing concepts apply to multihulls as well, you'll find the experience similar to monohull sailing with subtle but important differences. Those new to the sport have few preconceptions about how a multihull should perform. They find multihulls relatively easy and forgiving boats to learn on as they aren't trying to subdue years of monohull sailing instincts. Becoming proficient at sailing in general, and at sailing a multihull in particular, become one and the same. While experienced monohull sailors have a firm foundation in basic techniques they need to get over the mindset of comparing multihull sailing to sailing one-hulled ballasted boats. Once they can do that the process is easy. The boat you learn on tends to become your benchmark for what sailing is all about though handling...

Rigging a singlehanded dinghy

Laser Sailboat Block Block Technique

Popular single-handed dinghies such as the Laser, Topper, and Pico all have similar rigging, which is simple and quick to assemble. With practice, you should be able to get one of these boats rigged and ready to sail in about 15 minutes, though you may need help lifting the mast. The principal feature of all these dinghies is that they have no shrouds or forestay to support the mast. Instead, the mast is self-supporting, with the lower part fitting into a tubular mast step in the foredeck. The unstayed mast does not provide the same level of control as a fully stayed rig. it will bend and flex with the wind, but it maintains sufficient stability for the helmsman to manage the sail. Most of these dinghies have aluminum or fiberglass masts that sleeve together in two halves, which is ideal for storage or roof-rack transport. instead of being pulled up a track in the mast, the sail has a luff sleeve that slides over the mast. Check your dinghy's rigging manual before you start to...

The YD-40 is very close to the median L0A LW, is 1.22. hull length. Obviously this is due to the requirements of the accommodation. Even on very small yachts headroom for moderately tall people is required. The trend is shown in Fig 5.36, which shows the freeboard forward versus the waterline length. No upper and lower limits arc given, since the statistical basis for this graph is smaller than for the others above (only about 50 yachts).

A sloop from the land of catamarans

Unlike most of Hobie Cat's boats, the Holder 17 is neither a catamaran nor a product of the fertile mind of Hobie Alter, the multihull firm's namesake. It is instead a monomaran from the drawing board of businessman and designer Ron Holder. First came the cabin sloop, in 1981 the next year, a daysailer version was introduced. Best features The Holder has good sitting headroom compared to her comps. Foam flotation is intended to make her more or less sink-proof. Her relatively heavy swing keel keeps her minimum draft low for easy launching and retrieval at a ramp, while offering good stability with the keel in the down position. With a relatively high D L and low SA D compared with her comps, she should be stable in heavy air. Worst features The steel swing keel can be a pain in the neck to keep from rusting.

Catamaran Sailboat Wide Bodied Hulls

Hull Resistance Curves

From the schematics at the top of page 117, one can easily see how the wetted surface of each type of hull section differs, yet retains the same cross-sectional area. At one extreme, the deep V-type hull partitions, as employed by the Wharram catamarans, have 25 more wetted area than the contemporary type oval and semicircular hulls. Although the V-type sections offer excellent resistance against pounding and travel efficiently through the water, they are poor load carriers and are rarely used in today's industry. At the other end of the spectrum, the semicircular and not to take sharp entries to the extreme, as they can create a lot of waves that reach higher and farther aft, often compromising the bridgedeck clearance issue. Deeper hull sections will have a motion that is gentler and less jerky than a full-bodied, flat-bottomed hull. In contrast, flatter sections will resist the heeling forces of the wind and pitching motion far better. Since the water that is displaced by the hulls...

Storing and transporting a dinghy

Closed Transom Dinghy Drain

You can leave a dinghy on its dolly at the beach or in a boat park or marina and transport it by road on a trailer. For peace of mind and for everyone's safety, the boat should be tied down as securely as possible, with top and bottom covers for maximum protection. STORiNG A DINGHY When leaving a dinghy unattended, you may need to remove sails, foils, and all loose fittings dinghy gear is expensive to replace and theft does unfortunately happen. Pull halyards tight before you leave the boat when it is windy, people do not want to hear the unpleasant noise of wires banging against aluminum masts. Leave the drain bung open to allow air to circulate inside the hull. It makes good sense to remove the bung or carry spares, in case a neighboring boat owner decides to borrow it. Always use a good-quality top cover to protect the dinghy from ultraviolet light and rain, and make sure it is securely attached to the boat a boom-up design will help drain rainwater away from the dinghy. A bottom...

Fishing Boat Design Peculiarities

The 21ft. (Plate XXI.) design represents that of the Centipede, the most successful fishing boat ever turned out by Mr. D. Hatcher. In the drawing, the design is represented as for a boat of 22ft. 8in. length, but all the sections are exactly as they were in the 21ft. boat, the spacing between the sections only having been increased, so as to bring the length up to that necessary to make 5 tons with the same 8ft. beam. The water-lines, with the extra spacing as shown, certainly look very much better, even than they did in the 21ft. design, and no doubt a boat of the extra length would be a very fast and capable craft and, moreover, would be eligible for the 23ft. class. The Centipede, we might say, had very much less weight in her iron keel than given in the table, and the siding of her wood keel was less the siding of the keel has been increased solely with the object of getting more lead underneath it. * There is not mnoh donbt that a heavy lead keel (and a little leas beam if...

Catamaran launching and landing

Catamaran Trolley Slip

Two hulls mean that a special technique is needed to launch or retrieve a catamaran on its dolly. Once on the water, the catamaran provides the crew with an extremely stable platform as they prepare to leave the beach or come in from sailing. LAUNCHING A CATAMARAN As with any dinghy, you should rig the sails of a catamaran as close to the water as possible. A catamaran dolly has two wheels on a central axle, with supports for the twin hulls. To put the dolly in 1A catamaran is rigid enough the balance point of the twin hulls, push the catamaran into the water until it is deep enough to float. Then remove the dolly. CATAMARAN LAUNCHING AND LANDING Landing a catamaran is usually simple if the sand is soft you can even sail up the beach. Control your speed as you come ashore, and watch for swimmers. Keep the rudders down to maintain control if you do not lift them in time, they will knock up on impact with the

Introduction to catamarans

Razor Speed Sailing Boat

Small beach cats, such as the Hobie 16 featured in this section, require slightly different techniques from sailing a dinghy. While all the principles of wind, balance, and trim are the same, Go for speed is always the golden rule for catamaran sailors. ANATOMY OF A CATAMARAN Look at the photographs on this page, and it will become clear why catamarans can sail so fast. Both crews are flying the windward hull, with just the leeward hull in the water. That super-slim hull has much less wetted surface area than any dinghy, which means there is far less drag. In addition, each of these catamarans has a beam of 8 ft (2.43 m), which is wider than any conventional dinghy hull (although not as wide as some high performance dinghies fitted with wings or racks). The beam of a catamaran gives a crew with twin trapezes a huge amount of leverage, which allows them to sail with a bigger rig than a similar length monohull. KEEPING A CATAMARAN UP TO SPEED Catamarans perform best in moderate to fresh...

Dinghy racing courses

All dinghy races have the same elements and rules, designed to ensure that everyone enjoys safe sailing while battling for position around the course. Marker buoys ( marks ) indicate where to turn, with start and finish lines marked by a committee boat. end of the start line manages the countdown to the start. The object is for boats to cross the line as soon as possible after the starting signal. The first leg is normally a beat to the windward mark. On a windward-leeward course (below) the boats have a short beam reach to a spreader mark, then sail downwind to the leeward mark close to the start line. Classes with symmetrical spinnakers will sail directly downwind classes with asymmetric spinnakers and catamarans will sail downwind on a series of broad reaches. The race may continue with more circuits of the course, usually finishing close to the windward mark at the top of the course. A wonderful seascape near Cape Town, South Africa, provides a superb backdrop to a race between...

Preparing Your Boat For A Long Offshore Passage

Boats embarking on an offshore passage should be fully found, thoroughly seaworthy and manned by an experienced crew who are physically fit to face any weather. Storms at sea carrying winds of 30 knots or more with accompanying waves of 8 to 10 feet are not uncommon. It is important that your boat is capable of making headway in rough weather sea conditions. Dinghies Dinghies represent your sole means of inter-harbor transportation while cruising in the waters of Belize and Mexico. As there are very few docks to lie alongside, your dinghy will be in constant use and will really be put to the test. You will need to rely upon it in all kinds of weather. It should be of stout construction and stable in moderately rough seas. The typical 7-foot yacht tender will be inadequate for the regular use you will demand of it. My advice is to carry the biggest dinghy that you can possibly bring on deck, or deflate and stow below. Never go out in your dink without an anchor and oars. Carry extra...

Folkboat design imported from Hong Kong

Yacht Plans

Cheoy Lee Shipyard Cheoy Lee Shipyard of Hong Kong built various versions of this Folkboat-type hull (note similarities to the Contessa 26 on page 337) between 1957 and 1970, some in wood, others in fiberglass. The Mk III vessel pictured here was available either with a teak hull and teak superstructure, or with a fiberglass hull and teak decks and cabinhouse. The Mk III is distinct from the Mk I and Mk II mainly because of her doghouse cabin, which was possibly the idea of British designer Arthur Robb, though Tord Sunden is generally credited with the basic hull design. In any case, the boat won accolades for her good performance on transpacific and transatlantic voyages. Best features The Cheoy Lee artisans were well-known for their intricate teak carvings dragons and such with which they decorated the Flyer cabins, giving a luxurious effect. Worst features Though the teak woodwork was masterful, the hardware was sometimes made from inferior grades of metal, and would corrode or...

Bimini Solid Cover For Catamaran

Structure Aluminium Bass Boat

The Manta 42 is an evolution of the successful 40-footer which established the Florida company at the forefront of the US cruising catamaran market. Perfectly adapted to short-handed sailing, she features a unique camber-spar jib which is self-tacking. Unlike most production multihulls the Manta 42 has a laminated forward crossbeam, which is arched well over the waterline to reduce impacts in heavy seas. A very substantial stainless-steel aft-arch structure is available, which acts as antenna supports and dinghy davits. The Manta 42's solid bimini has integrated solar panels and spans the entire cockpit. Unique features include outside louvers, which keep solar radiation to a minimum and contribute to onboard comfort of this popular catamaran.

Evolution Of Boat Design

Between 1893 and 1914, the Herreshoff company designed seven advanced, powerful racing sloops. Five won the right to defend the America's Cup, and all five vanquished the challenger. Besides these majestic yachts, Herreshoff created a whole range of day boats and small yachts. The dominant yacht designer of the 20th century was another American, Olin Stephens. His reputation was established by the 51-ft (15.5-m) yawl Dorade, winner of the 1931 and 1933 transatlantic races. Influential on MIRROR DINGHY In the 1950s, Ricus van de Stadt of the Netherlands challenged the accepted wisdom that rudders should be hung on the trailing edge of the keel to reduce wetted surface and boost performance. The combination of separate hydro-dynamically efficient keels and rudders, coupled to the light plywood construction of the 39-ft (12-m) Zeevalk, foreshadowed the adoption of the fin and skeg hull design. Van de Stadt was one

Noteworthy Multihulls

N the following chapter I have attempted to objectively present and illustrate some of the popular cruising catamarans which are available today. Purposely omitting custom boat builders, the multihulls in this section represent about 90 of today's production cats. My company, Aeroyacht Ltd., an international dealership specializing in multihulls ranging from 35'-200', has seen several new builders come and go over the past few decades the following yards seem to have passed the test of time. Readers who are shopping for a catamaran have the possibility to consult our web site,, which features tests, movies and pictures, and keeps track of the newest developments of popular cruising multihulls.

Boat Handling under Sail

If you are a comparative newcomer to the world of sailing, you may think it odd that a chapter on handling under sail should precede one explaining how best to benefit from auxiliary power. Should you have come to cruising from dinghy sailing, however, it will seem entirely natural. There are even a few of us left who learned our sailing in cruisers without any power unit at all, save a sweep or a quant pole. In fact, sailing a yacht of moderate tonnage in close quarters can be as easy as motoring, so long as one or two rules are borne in mind. The most important elements of boat handling revolve around the various circumstances in which you may want to stop, or get under way. When it comes to boat handling, the one thing you do not do if you want to gauge the tide is consult the tide tables. Look at any fixed object with water flowing past it, including a moored or anchored vessel, and you'll see a bow-wave. That tells you all you need to know.

Boat Handling under Power

Sometimes a need arises to spin a vessel in her own length, or not much more. If your boat is unusually athletic and you are of the sort of disposition which peers unflinchingly into the cannon's mouth, you may still get away with a power turn, particularly if you can arrange your affairs so that she is swinging with the propeller. Most times, such a bold approach is better turned down, either to ease the strain on your heart or, more usually, because the yacht simply won't swivel tightly enough without help. In either case the answer is the short turn (Fig 6.2). disappointed, and there's another point if you know what she'll do, you can often control circumstances to minimise, or even neutralise, the effects of her wickedness. If you know your boat will go on shoving her stern to starboard for 30 yds (27 m or so), try to give her a solid sheer the other way before you start. The two may have cancelled out by the time the rudder gets a grip. You can also sometimes turn a cross-wind...

Climbing aboard a dinghy

Dinghies, as we explain in Chapter 1, are smaller boats (usually under 20 feet, or 6 meters) that carry no ballast (weight) in their movable centerboard (underwater fin). Dinghies can also tip over. Because with this book we want you to master sailing and not swimming, make sure that your first step into a dinghy is as near to its centerline (an imaginary line that runs down the center of the boat from end to end) as possible, near the midpoint from bow to stern (front to back). (If you're not careful, you may tip the boat and end up in the water.) If the dinghy has wire rigging (shrouds) connecting the mast (near or at its top) to the right and left sides of the boat for support, you may want to gently hold on for balance and to keep the boat near you as you step on board. You may also want to consider starting from a sitting or crouching position on the dock. In any case, keep your weight as low and close to the centerline as possible as you step aboard, as Figure 4-3 shows. JJ...

Storing Your Boat and Trailer

Proper storage prevents rust, mildew, dry rot, damaged wheel bearings, and weathered tires. Before storing your boat and trailer for the winter season, check out these tips If you cover your boat with a canvas tarp, prevent mildew and dry rot by allowing air to circulate under the cover. Do not cover your boat before it has dried. Do not use a nylon tarp, because it will trap moisture. If you store your boat in the water Do not store your boat where ice It is important to check on your boat several times throughout the winter, especially after severe storms.

Pulling your boat out of the water

Back the trailer down the ramp so that the trailer is partially under water and you attach the winch cable to your boat. Pull the boat up using the winch so that the bow of the boat contacts the bow rest. Carefully center the boat on the trailer so that it rests on the cradles evenly.

As Caesar was struck by the difference between the Roman sh ps and those of the Veneti, so Tacitus remarks that the ships of the Suiones differ from the Romans', too. Although these were not sailing ships nec velis ministrantur yet they were of the same design as those which were fitted with mast and sail.

If Your Boat Springs a Leak

Most leaks aboard fiberglass and aluminum boats result from malfunctioning through-hull fittings or hoses for bait wells and wash-down systems, and are not large enough to overcome the pumping ability of the bilge pump. However, for safety's sake, it's a good idea to carry some rubber stoppers that will plug your ittings in case something goes wrong with the valve or hose.

Taking the Dinghy through Surf

The gleaming white beach is a few yards ahead. I am studying the rise and fall of the sea from just outside the surf line, where the swell of the ocean feels the bottom and begins to break on the beach. Linda, seated in the stern of our nine-foot (2.8 meter) Dyer fiberglass dinghy, is relaxed, anticipating the children's joy. Elyse and Sarah, ages two and five, sit in the forward seat in their life jackets, gripping the gunwale with one hand and their buckets and shovels with the other. Just offshore Intermezzo stands quietly at anchor, a gentle swell occasionally lifting her stern. I give a light heave on the oars, and we coast forward. Now, eyes glued on the sea before me, I jockey the oars to keep our bow straight and the broad stern of the dinghy square to the oncoming wave. Too late I realize I've made a mistake. I have forgotten that a beach break looks much smaller from seaward, from the back side of the wave, than it actually With a rush, the surf has us in its grip. The bow...

Catamaran sailing in rough weather

Rough Weather Catamaran Sailing

The sealed hulls of catamarans enable them to be sailed safely in very rough conditions. But as with other high performance craft, medium strength wind conditions are best for building up your experience as the catamaran is sailing at its optimum speed. Crews can learn how to handle the trapeze system when tacking and how to move quickly up and down the gunwale to the aftermost trapezing position. However, only very experienced sailors should attempt to sail catamarans in strong winds and heavy seas. The two main points to bear in mind are to keep the boat moving as fast as possible when going to windward and to make sure the boat is balanced keeping the hulls level by sheeting the sails well out and bearing away in gusts. The catamarans above and below are both sailing in rough weather on a reach-the helmsman and crew are well aft. A number of smaller catamarans can usually be successfully righted by pushing the bows or sterns (it doesn't matter which) down into the water until they

Royal Caroline And The Development Of English Fast Sailing Ships

Gun Squirrel Sixth Rate

The eighteenth century saw a new introduction of science into the art of naval architecture. The first attempts to apply mathematical criteria to shipbuilding were made mainly in France. There, mathematics and experimental scientific studies were widespread and traditional shipbuilding methods were not so deep-rooted as in England. There was a French school of physics and applied mathematics engaged in the study of the optimum shape for hulls. Some of the finest scientists of the time were involved their results, if not brilliant, were certainly a positive contribution. When it was planned to buy in a captured ship for the navy, a technical commission consisting of representatives of royal dockyards had to decide on the appropriateness of the acquisition, a fair price, the repairs needed and so on. Then, if the prize was purchased, the captain had to make a report on the ship's sailing qualities, as was the case for ships built in England. The captain's sailing quality reports were...

Saifing on a Catamaran

If you know how to sail a keelboat or dinghy, then you can sail a catamaran, because a catamaran, also commonly referred to as a cat, is simply a sailboat with two hulls instead of one. Figure 11-9 shows a basic cat. Sure, some multi-hulls are big, heavy cruisers, but we're talking about the kind you launch off a beach, around 20 feet (6 meters) or smaller. Note that a cat has some features you don't find on other sailboats, including a crossbar to hold its unique twin hulls in place the trampoline rope mesh or fabric surface between the two hulls full-length battens in the mainsail and a rotating mast to optimize sail shape. Because the principles of sailing a catamaran are the same as for any boat, this section focuses on some areas where you run into significant differences. The big difference between cats and dinghies is their speed. Cats are faster on almost every point of sail, in every wind condition. The reason for the speed is twofold The narrow hulls cause very little drag,...

It Aint Flipper Stop Your Boat from Porpoising

This creates fore-and-aft rocking called porpoising. In the extremes, it's a bit like riding a bucking horse. You stop it by trimming in a bit, or by giving more throttle, because the faster you go, the more weight the combination of engine power, prop, and hull design can support. What if your boat porpoises all the time Chances are you have too much weight forward, making it impossible for the prop to adequately lift the bow. A quick fix is to move passengers, ice chests, or other heavy gear aft. Or you may want tc switch from a three-blade prop to a four-blade the added blade area sometimes helps in giving more lift.

The Development Of The Sailing Ship In The Nineteenth And Twentieth Centuries

One of the first war vessels to be laid down n the new century was the Caledonia, 205 feet long and of 261G tons. This was in the year 1802, but she was not launched until six years later. Carrying 120 guns she was a first-rate, and was based on the design of the Commerce de Marseilles, which we mentioned in the last chapter. There is a model both of the Commerce de Marseilles and of the Caledonia in the...

Flush Dinghy Outboard Motors While Cruising

The major problem is that multihulls are more affected by drift and windage at low speeds. A line towed astern may drag the person along, further weakening them and dragging them under. If they are in a sling or lifering get them to face backwards and shorten the line as soon as the person is attached. Multihulls also lose way very quickly in any chop. Have motor power ready to help hold station. Of all the seamanship safety techniques that should be practised the man overboard recovery is the most important. Every multihull differs in its speed, layout of equipment, manoeuvrability and drift. Practice on a regular basis the recovery of an object as quickly as possible. Time yourself and your crew. The motion of a multihull mast has both advantages and disadvantages when it has to be climbed. At sea this is a potentially dangerous exercise. The mast, although remaining mainly upright, is prone to rapid movements in any direction as the multihull goes over waves. Multihull Seamanship...

Maintaining Your Boat and Engine

Maintain your boat and engine so you'll be safe. Your boat and engine will also last longer so you'll have more fun on the water. Check the inside and outside of the hull when your boat is out of the water. Avoid using toxic cleaners and paints on your boat. Chemical products should only be used on your boat when it is out of and away from the water. These products must be kept out of the water and disposed of properly.

The sisters, 18 and 12, respectively, scored 12 points in nine races, and became the first female team to win the event. Because Sarah will age out of the 2007 event, runners-up Eric Raybon and Jason Bilow will defend the title at next year's Youth Multihull Regatta in Kingston, Ontario, which is also the qualifier for the 2007 ISAF Youth Worlds.

Row Row Row Your Boat

Rowing differs from paddling in that the paddles of a rowboat the oars are secured in oarlocks. This creates a lever, allowing a much longer stroke and making it easier to apply the force needed to move the boat. This is why many rowboats can be both wider and heavier than canoes and kayaks. Most rowboats except sculls also have square sterns, so that they can be operated with electrical or gasoline motors as well. Rowboats used to be planked or plywood, and a few custom builders still lovingly put together such collector's items. But the most common material in rowboats today is aluminum.

Nesting Dinghies

Plywood Pram Boat Plans

Consider a tender's design criteria The boat must be small, yet it will be called upon to carry huge loads it should row easily, but it will be wide relative to its meager length in order to gain capacity in the interest of easy handling, it ought not weigh too much, yet we know it will suffer terrible abuse. No doubt about it, drawing a proper dinghy can be an exercise in contradiction. The three dinghies shown here address the problems of stowage, performance, and capacity by splitting apart amidships. The resulting pieces will nest neatly on the deck of a cruising boat or in a shoreside storage shed. The smallest of the trio, Danny Greene's 10-foot 4-inch Chameleon, folds into a 5-foot 3-inch package that lives on the forward deck of his 34-foot ketch. After bisection, Mike Kaufman's and Charles Strayer's longer (about 16-foot) boats can be nested or they can sail off as separate, more or less equal, 8-foot halves. Kaufman describes the advantages of the type while explaining the...

Boat Selection

People cruising on larger boats often get stuck in the bind of having to depend on finding pick-up crew in different ports to be able to safely manage their boat on ocean passages. Crew problems are one of the most persistent and common problems on cruising boats. It's easy to find plenty of friends and family members that are excited about sailing with you when you first leave home, but as you get further away and airfare becomes more expensive, finding crew becomes difficult, and you may not be comfortable trusting your boat and Yon must be prepared to sinqlehand your boat. You or your partner wife crew may become ill (or even severely seasick) leaving one person to handle everything. In respect to this possibility it makes sense to have a boat vith manageable sized sails and a totally dependable wind-vane self-steering system and an electric autopilot as well. Fatigue is the 1 cause of short-handed or singlehanded boats being lost on the rocks or reefs while making landfall, so it...

Tacking a dinghy

If sailing a two-handed dinghy, the crew has a simple role keeping the jib sheeted in until the wind catches on the other side, causing it to back, which helps push the bow around. As soon as it is clear, the boat will complete the tack and the crew should let go of the old sheet, cross over the boat (facing forward), and pull in on the new side.


Unicorn Catamaran

Catamarans are lightweight craft which can carry a larger sail area and therefore can sail faster than monohtilled boats, because of the greater stability given by the twin-hulled design. Apart from the design features made necessary by the twin hulls, such as the central bridge deck trampoline, twin rudders and a forestay bridle (see opposite), catamarans have several features not found on other high performance boats to help you cope with the higher speeds. The sails are particularly flat and the mainsail has full-length battens to keep il tensioned. Both the mainsail and jib are controlled by complex (multi-purchase) pulley systems for easier handling. A rotating mast is also litted which allows a more effective air flow. Sailing a catamaran requires a slightly different technique to sailing a monohulled dinghy. Because catamarans are generally more Catamaran types Some different types of catamarans are the Hobie, far right, which is a two-man catamaran, the Unicorn (center right)...

After I left the Caribbean in 1975, I ran into Don only infrequently until our circles joined again through Cruising World. I well remember Don hailing me across the pressroom at the 1999 London Boat Show and bending my ear about the articles he should be writing for the magazine. Don pursues editors like a terrier, whether it's to promote the latest revision of one of his guides, a new chart from publisher Imray-Iolaire, or an article about staying out of trouble in the Atlantic Ocean (see Caribbean Exit Lines, March 2004). To his credit, this persistence has ensured that for 40 years (his Cruising Guide to the Lesser Antilles first appeared in 1966), countless readers and sailors have benefited from his long and hard-won experience. Most of my recent sailing has been short trips between shore-side plug-ins aboard modern cruising boats designed for short-handed crews. A week aboard lolaire represented a big step back in time nearly 40 years, in fact, to the days I sailed with...

The Maine Cat 41 is a little masterpiece, built in Maine by craftsmen who have also produced the popular Maine Cat 30. The new 41-footer maintains the tradition of an open bridgedeck design, good sailing performance and a practical and exceptionally well-finished interior. This daggerboard-equipped cat can easily be single-handed from a central wheel and navigation station located in the forward part of the cockpit. In inclement weather the entire bridge deck can be converted into an enclosure, via side curtains which quickly attach to the rigid bimini. The Maine Cat 41 has excellent seakeeping abilities, thanks to her high bridgedeck clearance, conservative sail plan and buoyant hulls. This catamaran is an outstanding choice for people looking for a spirited daysailer and safe passage maker.

Wood Spars

When we were very young, and wished to give wings and magic to our skiffs, we'd go deep into a spruce swamp to find a tree that had died standing. Trim off the small dead limbs, smooth it with a drawknife, keep the taper that came naturally, maybe fi t a sheave at the top for a halyard, step it in a hole in the forward thwart, fit it with some kind of sail (made from a discarded bedsheet or a painter's drop cloth) and the winds of Heaven were our companions in a glorious voyage to the Happy-Isles. These were four miles (and half the World away) downwind. If the tide didn't favor, we might have to row a spell on the return voyage. It was worth it. That little spar was the ultimate key to romance and adventure.

Sailing a catamaran

Catamaran Sailing Techniques

If the wind is strong enough to lift the windward hull, a catamaran will always sail on the apparent wind meaning that speed forward through the water tightens the angle of the wind so that it always appears to be blowing from ahead, irrespective of the course sailed. The principal requirement of catamaran sailing is to build up apparent wind. When beating upwind, do not try to sail as close to the wind as possible, as with a conventional dinghy. Instead, bear off a few degrees to power up the rig's forward drive. Increased speed will more than compensate for lack of pointing. Like any boat, a catamaran is at its fastest on a reach. On a run, with airflow over one side of the sails only, and both hulls down in the water, a catamaran is slow. To compensate, catamaran sailors Sailing downwind on a three-sail reach, the mainsail is sheeted almost on the centerline due to the apparent wind angle and the speed of the catamaran.

Dinghy Sailing

Materials and displacement transformed dinghy design too. Plywood sped up building time, which generated a post-World War II dinghy boom. Flat panels and the simple curvature allowed by just four pieces of plywood were simple to construct. This particularly appealed to the do-it-yourself builder, the best example being the 11-ft (3.3-m) Mirror dinghy, designed by Jack Holt. Another development has been that of planing hulls. Planing means that the boat is able to rise above the theoretical limitation of its displacement and sail at much higher speeds. In the 1990s, big sail plans especially large Van de Stadt was an innovator in GRP production boats. Small sloops like the Pionier were mass produced and therefore affordable they dominated the cruiser racer market in the 1970s. asymmetric spinnakers, enabled even higher top speeds. Keelboats mirrored this trend with lighter, better mannered hulls able to handle much greater power from their rigs. No dinghy has made a bigger impact than...

Types of dinghy

Twin Hulls Racing Boat

There is a huge range of different dinghy designs and classes from which to select the boat that will best suit you, each offering a particular sailing experience for varying ages and abilities. The first decision to make is whether to sail single-handed or with a crew. Double-handers are sailed by a helmsman and one crew, who have both a mainsail and jib to drive the boat, with the option of a spinnaker for use downwind. It is rewarding to work as part of a team in which the crew plays an important role, and you may be glad of the company while you sail. Larger dinghies used for recreational sailing may have sufficient space and buoyancy to carry four or five people, making them ideal for family sailing (see Types of keelboat, pp. 96-97). Popular single-handers, such as the Laser, Pico, Topper, and Open Bic, are extremely simple dinghies with just one sail and an unstayed rig. This makes them cheap to own and maintain, quick to assemble, and easy to store When sailing a...

Catamaran Jib Camber

Cut Away Photo Catamaran

The main driving power of the working sail plan of a multihull is derived from its mainsail. Typically they are fully battened and loose-footed to permit maximum camber adjustment. Due to the higher speeds of multihulls, sails are frequently cut much flatter and, generally, are also of heavier construction than those on a monohull. mainsails can have up to 60 more surface area than a conventional 18 roach as seen on the typical monohull main. The additional area can be applied either to making the boat go faster, or to reducing the rig height and the overall Center of Gravity (CG). But the efficiency of the sail plan increases with its aspect ratio, and the taller the luff is, relative to the length of the foot, the more power the rig will generate. However, care must be taken that the Center of Effort (CE) is not moved too high as that will affect stability, and might even induce pitching, which compromises airflow over the sails. Interestingly, the phenomenon of weather- and...

Hull Speed

Bow Wave Physics

Hull speed is a phenomenon of displacement boats, and not of planing boats. Most sailing boats and all ships displace water move it aside as they plow through it. Planing craft, such as most motor boats, glide over the top like a surfboard. It takes more energy to push water aside than it does to slide over the top of it, and so displacement boats move at a more sedate pace than their lighter planing cousins. Some small sailing boats can be made to plane, but the general rule is that sailing boats are of the displacement type. Hull speed is usually an upper limit to the speed of displacement boats.* It is unsurprising that such a limit exists we have seen how drag increases with speed, and so sooner or later drag will balance out the drive force and a sailboat will not be able to go faster. Yet there is a surprise in store for those of you who are not familiar with sailing the hull speed of a given boat depends on its hull length at the waterline. It is not obvious from a simple...

In this chapter we describe the theories behind the hydrodynamic design of the hull. We start by introducing the various forces acting on a sailing yacht, and explain how the forces are created by the flow around the hull. Formulae will be given for the force components, and the trade-offs in the hull design process will be dealt with at some length. Finally, there is a section on hull statistics, which may be used as a guide for selecting the main dimensions of a new design.

Kids and Dinghies

Boat Selfreliance

We can tell you from firsthand experience (as kids, parents, and grandparents) that there is no greater thrill for the younger generation than having command of a dinghy. It is such a feeling of power and freedom that unless you have experienced it yourself, as a child, it is difficult to comprehend. Getting kids out on their own in the dink teaches them self-reliance, and brings them closer to understanding and enjoying the operation of the mother vessel. The key is to let them stretch their wings in a safe manner.

Boat Handling

Boat handling drills are the key to any successful campaign. You need to be able to get your boat around the race course before you start to race. When you first start high performance sailing you need to sort out your boat handling in under 15 knots before you go out in 25 Until your boat handling is sorted it will often be more productive (in terms of your long-term development) to work on boat handling than to go racing. You cannot race effectively if your boat handling is not up to scratch it will impact on your race tactics and strategy. Undoubtedly the best way to improve all aspects of boat handling is that old clich 'time on the water'. However, the more specific and demanding you make the exercises, the greater the potential gains. It is also good to change exercises to add variety and keep motivation to train high. Once good boat handling has been achieved, you can rediscover key skills very quickly after a reasonable break. Boat handling routines can also be a good way of...

Dinghy Safety

Life Jacket With Crotch Straps

Wearing a buoyancy aid is strongly recommended for dinghy sailing. As its name suggests, it helps flotation in the water should the crew capsize. Buoyancy aids are recommended only for use by swimmers in sheltered waters when help is close to hand. Unlike lifejackets, they are not guaranteed to turn a person from a face-down position in the water. Flotation is measured in Newtons (N) 10N 2.2 lb (1 kg) flotation. You should always get professional advice when fitting a buoyancy aid, but as a rule of thumb 50N is suitable for sailors Pull-on buoyancy aids with side-entry zippers are favored by dinghy racers. The sailor's upper body and arms are unrestricted, with elasticated sides, shoulders, and hem for a snug fit. The buoyancy aid is worn over the trapeze harness with the hem pulled in tight All dinghy crew should carry a purpose-designed safety knife, which must be accessible during a capsize. This is to cut through rope or cord if a crew member gets trapped under the boat or sail.

Hull Construction

Bounty's draught shows a total of eleven station lines expressed as frame lines on the body plan. These are the Dead Flat, A to D forward and 1 to 6 aft. These lines were probably determined by the Deptford Yard surveyor, by taking internal measurements (to the outside of frames) and while they give enough information for a draughtsman to describe the ship's hull shape on paper, there are not enough of them for a shipwright to build a vessel. I arrived at Bounty's framing plan by laying out the given station lines, from the draught, and assigning further lines at 4-foot intervals these are the Dead Flat, (A) to O forward, and (3) to 24 aft, (The bracketed frame numbers occur amidships where all frames are identical to the frame at the Dead Flat), This system works perfectly if one allows that the surveyor took some measurements on the fore face of the frames and some measurements on the aft face, and that it was not essential that the frames he chose coincided with the original...

Dinghy maintenance

A sailing dinghy operates in a harsh environment that can combine corrosive salt water, abrasive sand, and extreme stress from wind and waves. A little care, repair, and occasional replacement are necessary to ensure that you continue to enjoy good, trouble-free sailing. To minimize the need for repairs to sails, fittings, and hull, be sure to take particular care when storing and transporting your boat (see pp.164 165 and pp.166-167). Regularly check the tightness of screws, bolts, and fittings, particularly at the transom, and inspect the rope and wires. There are times when it is impossible to avoid impact damage to the hull and deck of a dinghy. Rotomolded plastic should withstand hard knocks and only sustain minor scratches. More serious damage requires professional repair. Fiberglass construction is far more susceptible to minor damage to the gelcoat finish. Any damage must be repaired as soon as possible to prevent water from seeping into the laminate. Dinghy specialists sell a...


Gravity Sign Hull

The catamaran is the first application of torques because its geometry makes estimates relatively simple. A typical catamaran sailboat has two narrow canoe-like hulls that are separated by about half a boat length. The mast is centered in a structure rigidly connecting the two hulls. Over the ages, variations of the catamaran have been invented many times and in many places. The word catamaran kattumaran tied logs comes from the Indian Tamil language. Polynesians colonized much of the Pacific in catamaran-like doubled canoes. 4.4.1 Catamaran Roll and Capsize Normally, catamarans don't tip much, unless they tip over. The forces jeopardizing a catamaran on the edge of stability for roll are shown in Figure 4.2. For the boat in (a), the left hull is about to leave the water. Any increase in sail force produces the tipping shown in (b). The second torque T2 is produced by the equal and opposite horizontal force of the water on the catamaran hull that keeps it from sliding sideways. (For...

Menorca Sailing Monohull

Ar are sight on the world's waters 20 years ago, catamarans are now ubiquitous. At boat shows, they elbow aside monohulls, clamoring for attention. And they get it. Their mere presence demands it. They' re big and brash, they offer bountiful creature comforts, and they revel Catamarans have evolved over the past three decades, and the public perception of the cruising cat has gone from oddball and dubious to mature and proven. Viewed more clearly through the lens of experience, the spectacular flips of some early racing models are accepted now as the inevitable outcome of experimentation and the price of progress. Modern cats have benefited from the oops moments of these pioneers, and they're now considered at least as safe as monohulls. The first question out of the mouths of visitors aboard catamarans isn't 'Will it tip over ' says Hugh Murray, president of The Catamaran Company, which handles cats in every capacity, from new-boat dealer to used-boat broker to charter broker.

Keen on Kayaks

Kayaks were the invention of the Inuit peoples (formerly called Eskimos ) of the Arctic. They were hunting boats frames made of wood or bone with animal skins stretched over them. They were light and tough but not so light and tough as modern composite plastic and Kevlar versions. Kayaks differ from canoes primarily in that the top is closed over in most, helping to keep water out. Consequently, bow and stern do not have to be upswept as in a canoe, and wind resistance is lessened as a result. Most kayaks are designed for one person only, although a few, such as the Pamlico series from Wilderness Systems, can handle two people. Kayaks are narrower than canoes, usually designed for only one person, and feature a closed deck rather than an open hull. They're designed to be paddled with a two-bladed paddle. Kayaks tend to be narrower in the beam than canoes and are designed for double-bladed paddles that dip on both sides, rather than the single-blade used on one side as in the canoe....

Using Your Dinghy

Wooden Sunfish Plans

Figure 17-2 shows an idyllic cruising scene. A key component to that fun is the dinghy tied behind the cruising boat. Because your dinghy is often your ticket to freedom on a cruise, you want to make sure that it doesn't float away. The following tips can make life afloat with a dinghy more enjoyable 1 Bring a paddle. An outboard engine may power your dinghy, but make sure that you have some alternate means of propulsion just in case 1 Stop that banging. Assuming your dinghy is a rubber inflatable, you can tie it so the engine can't hit the hull of your sailboat. But kayaks and other water toys have a habit of banging against the hull as the wind shifts in the anchorage at 3 a.m., so you may want to pull them up on the dinghy at night. 1 Tie your dinghy securely. Whether you're towing your dinghy behind the boat or leaving it high and dry on an idyllic beach while you do some exploring, make sure that you tie it up well. Use a bowline knot, or tie your dinghy around a horn cleat, as...

Boat Preparation

Always carry either a standard hard dinghy or an inflatable with wooden floor boards to give its bottom rigidity. An outboard motor is essential because in many anchorages tidal currents, rough water, and long distances to shore, make rowing impossible. What is more ludicrous or frustrating than having a small inflatable without a bottom stiffener and a tiny outboard hanging on the stem, with its carburetor dipping in the sea as you try to make two knots into a twenty knot head wind Always carry oars, a small anchor and rode, life jackets, and a flashlight on board. Drifting helplessly out to sea is a frustrating fate.


Dinghy hulls are flat at the stern with a narrower, V-shaped bow to promote upwind performance and slice through waves. Dinghies do not have fixed keels but moveable daggerboards or centerboards. Unencumbered by the drag of a heavy fixed keel, the typical lightweight dinghy hull is able to start DINGHY HULL SHAPES Dinghy design has evolved towards wider, flatter hulls, which are more stable. Many hulls have a bottom considerably narrower than the deck to increase performance by reducing wetted surface area, but at the cost of stability.

Righting catamarans

Catamaran capsizes are often spectacular because of the speed at which the boat is travelling when the capsize occurs. Ironically, however, a catamaran can capsize just as easily when it is moving slowly if the sails are over-sheeted. This results in the crew being unable to get the boat to respond quickly enough if a wind shift occurs and the boat then capsizes to leeward. By far the most spectacular, but rather less common, form of capsize happens when the bows dig into a wave and the boat somersaults forward, stern-over-bow. This normally only happens in rough conditions when the boat is travelling at very high speed. When it does happen, the first priority is to make sure the crew is released from the trapeze. Catamarans invert easily and therefore your capsize drill needs to be rapid and well rehearsed. The method for righting a small catamaran differs from that for a bigger one. The smaller types, like the Dart for example, can be righted by immersing the bows or sterns until...

Launching your boat

Help prevent the spread of animals and plants that cause a nuisance in California waters. Aquatic plants and animals that are transported to a place where they're not native can cause problems for native organisms and upset the natural ecosystem. Remove all aquatic plants and drain water from your boat and trailer when you pull your boat out of the water. Aquatic nuisance species in California include water hyacinth, hydrilla, Egeria densa, Amur River clam, Chinese mitten crab, European green crab, and the New Zealand Sea Slug.

Who Needs a Rowboat

You do, if you want to take a family of four or five for a trip via muscle power. Canoes and kayaks don't have space for this many people, but rowboats usually have at least three bench seats where a number of passengers can sit in comfort. Be sure to check the capacity plate so that you don't overload, though. It's mounted on the console or transom by the manufacturer and lists the safe load capacity for the boat. Although rowboats are larger and heavier than canoes and kayaks, many Rowboats are also a favorite of anglers because of their great stability they allow you to stand up to cast and to survey the water for fish, something that's pretty tricky in most canoes and kayaks. Rowboats are also better suited for motors than other boats that are regularly moved by muscle power. Most can handle kickers of 5 to 10 horses, and many can even plane with adequate power, giving a fast ride home when you're done rowing around to sneak up on the fish or photograph the wildlife. Rowboats made...

Swedish Lightships

Swedish lightships may exhibit the following signals if a vessel is observed standing into danger. A gun may be fired, the Morse letter U may be made by siren or flashing light, or the International Code flag U is displayed. Lightships out of position discontinue their characteristic lights and fog signals. If possible, they will lower their day-marks and make the following signals

Refueling Your Boat

Gasoline is very dangerous in boats because the bowl shape of the hull interior traps any spilled or leaking fuel. The closed decks and compartments hold in leaking vapors, creating a fuel-air bomb that is only lacking a spark to turn your boat into a Roman candle. 1. Make sure your boat is properly tied to the fuel dock. Nothing is more distracting than having the boat begin to leave the docks with the fuel hose in the filler Incompetent clearing can make it happen, so if you let Uncle George handle the lines, make sure he knows how to make things stay put. All of this is not to say that your boat is likely to explode at any moment. Fuel fires afloat are extremely rare. But they do happen, and the results can be catastrophic. You can't simply run out in the street and wait for the fire department.

Getting to Your Ship

I've already touched on the subject of transfers from the airport to your ship. It's easy if the cruise line will be providing the transfers (that is, you book through their air program). Otherwise, the best bet in most places is to take a taxi, which can cost a considerable amount. Public transportation between the airport and cruise ship terminal in all of the gateway cities for Mexican Riviera and Baja cruises is-to put it mildly-very limited and can't be considered as a practical solution. In other words, do you really want to lug around four pieces of luggage on a train or bus


The best dinghy is one that can be safely stowed away at sea, is accessible in an emergency, is capable of rowing out to set an anchor and is light enough to help keep the payload down. There is plenty of deck storage area on a multihull although there are some traps. Multihull Seamanship Rule Do not store a dinghy on trampoline netting This is especially true of forward trampoline netting. A decent wave, either over the top or from under the netting may take both trampoline and dinghy with it. The force behind a dinghy full of water travelling at speed is very high. Few trampolines will survive. Towing a dinghy needs care. There is a wind tunnel effect on catamarans that flip lighter model dinghies. The wave pattern of both trimarans and catamarans also has an effect on the way a towed dinghy will ride. The dinghy painter needs to be long enough to adjust the tow length to place the dinghy in the best position in the wave pattern. Better still pull the dinghy aboard. There is no...

Multihull Seamanship

Sailing is an Art and there are no defining right or wrong ways to perform maneuvers on a boat. Polynesian seafarers who plowed across the Pacific already knew this thousands of years ago. Their knowledge of navigation and seamanship was handed down by the leaders to their heirs and treated like a closely guarded mystic treasure of knowledge. Their expertise in navigation and sailing giant oceangoing multihulls was responsible for the successful colonization of distant islands. Polynesian mariners did not have the advantage of today's hightech materials, electronics and sailhandling systems. All they could rely upon was their ability to handle their multihulls in any weather. So let's remember, however well designed, constructed and equipped your cat is, the one thing that will ensure its safety are experience, understanding and above all good seamanship. It is my firm belief that every sailor should be able to singlehand his multihull unless the boat is set up as a fully crewed...

Selecting a dinghy

Dinghies are usually smaller than keelboats (shorter than 20 feet, or 6 meters) and have a lightweight, retractable fin instead of a heavy lead keel, and therefore are less stable and can flip over. In our experience, the scariest parts about dinghy sailing for small children are the sudden changes in heel the tipping motion and the fear of capsizing (tipping over). But if you're taking the kids out in a dinghy, here are tips to make the day a success, starting with tips before you leave the shore Although dinghies offer the thrill of being close to the water, they have less room, and often each crew member has a specific job. That makes caring for the comfort, entertainment, and safety of a small child difficult, no matter how good a sailor you are.

Dinghy Or Yacht

A dinghy is a small, open boat that is in very close contact with wind and water. it may tip right over, but it provides an intimate experience of sailing every movement can have an impact on the boat's performance. A yacht is much larger and can provide very comfortable accommodation for several people on board, with the advantage that it cannot tip over completely, thanks to a heavy keel underneath. But if you have never sailed before, there are many advantages to learning to sail in a dinghy, whatever your long-term ambitions may be. Handling a dinghy provides basic sailing expertise, and you will make quick progress if you move on to sail a yacht, which works on the same principles on a larger scale. Owning a yacht is likely to require a much greater commitment than a dinghy in cost and time.

Kayak Handling

Kayaks are paddled about like free-style swimmers swim left-right-left-right. This keeps you going straight as long as there's no wind or current to push you sideways, and as long as you put the same force and depth into strokes on each side. The kayak paddle can also be used as a rudder to turn or straighten the boat once it's underway. This is done by dipping the paddle deep into the water on the side toward which you want to turn, and then levering it outward slightly. Keep the pressure on as long as you want to continue the turn, and then go back to the standard alternating strokes. f- Its possibl e to pull most kayaks sideways (tougher with the longer sea-touring models). You do this by leaning to one side, tilting the paddle overhead to that side, and reaching out with the bottom blade as far as possible to draw the boat in that direction. It's handy for getting close to a dock or getting away from an overhanging bank.

Catamaran handling

The techniques for catamaran handling vary to some extent from one design to another. Whether you choose to sail a two-man boat or a single-hander, you will need to be Ht. Don't let the apparent lateral stability of the twin-hulled design lull you into a false sense of security ability to concentrate and quick reactions are essential to cope with the higher speeds and most catamarans are unsuitable for beginners. You also need to be quite strong although steering a catamaran normally only takes minor adjustments of the tiller, pushing or pulling the tiller over to tack or gybe the boat requires considerable effort. To sail a catamaran well you need to have a very clear understanding of the difference between true and apparent wind (see Aerodynamics section) as the speed at which the catamaran sails exaggerates the difference between them, and the sails must be trimmed accordingly otherwise the boat will slow down or stall. Correct crew position is important in order to keep the boat...
