Recondition Batteries at Home
For lakes and inshore areas, you can't beat a cellular phone. It's immediate, easy to use, dependable, and something that most families already own. Just be sure to put the phone in a waterproof container, and keep the battery charged a connector to the 12-volt system is a great plus. However, most cell phones won't work when they get too far from the nearest tower many won't function more than 25 miles offshore.
Much has been written about marine DC-charging systems, and with good reason When they fail, they can leave the average cruising sailor without battery power for the lights or engine just when it'd be appreciated the most. This month, however, I'll try to clarify some of the maintenance-related mysteries behind the machinery that keeps your batteries charged up and full of life.
However, they put out only 5 watts, versus the 25 watts of a fixed system, and the antennas are only about six inches long, so the range is limited to about five miles. Also, they can't be left on continuously because their batteries soon run down, so they're not the best first radio for your boat. However, most have rechargeable batteries just plug them into a charger attached to an AC outlet, and they're back to full power overnight. Rechargeable batteries in handheld VHF radios tend to lose a lot of reliability as they age, especially battery types that have a memory and must be fully depleted before being fully recharged. Rechargeable also have poor shelf life when away from the charger. For these reasons, many boaters who don't have an on-board charging system for their VHF have a strong preference for disposable batteries instead of rechargeable. That way, all you have to do is carry a spare set of alkalines, and you'll always have radio power in an emergency. Also keep in mind...
Radio Direction Finding. (ed. note No GPS in those days ) You are unlikely to need R.D.F. while cruising by dinghy. If you were crossing one of the Great Lakes, and got blown off course by a storm, and if it were night or poor visibility by the time things had settled down and you were ready to start sailing, you would be glad to have it. For most cruises, I would regard it as an unnecessary luxury. The Space-Age Pocket R.D.F. from England measures six by three by one-and-a-half inches, with a luminous compass, and is a good one ( 180). Avoid radios with rechargeable batteries (like the Sea-Spot 2 R.D.F.) for dinghy cruising or you are likely to be stuck with a flat battery, and they will not take dry cell spares.
An electric winch that draws on the power of your tow-vehicle battery takes the work out of loading a heavy boat, although it may cost about 10 times as much as a manual winch 300 for a model that can handle up to 10,000 pounds. A nice feature is that you can turn the power winch on remotely by pulling on a cord, which allows you to push your boat into position and at the same time activate the winch very handy if you have to load your boat yourself.

Siren is a good design for an overnight cruiser for two adults and two small children Versus her comps, she has the lowest SA D, making for relatively good stability, but at the expense of light-air performance. And she has the lowest draft, meaning relatively easy launching and retreiving from a trailer. Best features Below she has foam flotation, a molded-in icebox, space for a stove and a toilet. Space is allocated in the cockpit for a gas tank and storage battery though its aft location may not be optimal for proper hull trim. Construction and finish are above average. Worst features Among her comps, she has the lowest Space Index, although for any 17-footer space is going to be tight. A steel centerboard, even though galvanized, may cause maintenance problems, particularly in salt water. Her outboard well doesn't permit an engine to be tilted, causing drag unless engine is removed and stowed a good reason to choose a small, lightweight engine.
Battery life (for the MDWD) is an issue two hours or less. Extra batteries and a charging unit onboard are essential extras with this unit. Keep in mind that the Toughbook MDWD is only moisture and dust resistant. A more durable remote screen is the Bootronik M12Race, which is waterproof. The M12Race isn't wireless, and isn't a touch screen, but comes with an integral mouse and a long, waterproof power and data cable.
Time is of essence From the point at which you begin to open up the engine, through this step you can't stop. Once the wet surfaces are exposed to air they start to rust, so you have to keep going until you get each cylinder oiled. Keep an eye on battery voltage level. There's a lot of cranking to be done, and you need to have some juice left over for starting the engine when you're finished.
Chlorine is generated by running an electrical current through salt water. Fortunately copper (the main component of marine electrical wiring) and stainless steel do not generate chlorine at 12 volts. The copper quickly forms an insoluble coating and becomes non-reactive and stainless steel simply loses its passivity and dissolves slowly under the influence of a potential. The one metal that shows a tendency to produce chlorine is lead. The battery terminals are the main culprit. The average marine battery with exposed terminals produces 4 ppm chlorine gas cubic metre of air minute. Chlorine is produced mainly by battery terminals therefore avoid them coming in contact with sea water. This may be done by simply greasing the terminals regularly after the connections have been made or spraying them with a marine moisture repellent.
Powerboats can be propelled by outboard, inboard, stern-drive (also known as inboard outboard) or jet drive motors. An outboard motor clamps directly to the transom or can be mounted using special brackets. Outboard motors range in size from 2 to 275 horse-power. Outboard engines run on either gasoline or battery power.
Before each ocean passage, I pack the radio in a waterproof pouch inside our abandon ship bag, along with an optional battery pack filled with alkaline AA batteries (CM12-G battery pack for M-ll, BP-80 for M-7 radio). ACR now builds a SOLAS waterproof survival VHF ( 722 399) with 5 yr. sealed lithium battery, ideal for packing inside a liferaft, but not as versatile as the ICOMs.

The question we are most frequently asked is, How much does it cost to cruise Our response It takes as much as you have We had 600 a month to spend our first year cruising, after outfitting. We sailed to remote anchorages, had no break downs or haul-out charges and stayed within this budget. Our second year out we had 1,000 a month to spend - guess how much we spent Right, a little over 1,000 a month including a haul-out, replacing two deep-cycle batteries and some touring and nights in hotels. Interior woodwork, cushion cleaning, new battery and chain boxes 800.00 Deep cycle batteries 198.00
Charging of batteries will produce sufficient hydrogen gas which, if trapped and ignited, will produce an explosion. This applies particularly to boats having their batteries under the seats of the after part of the boat. If the battery is charged (other than from the boat engine generator) while in the boat, hydrogen may collect under the seats and, if not removed, may be ignited by a spark from the battery caused by a loose terminal or when charging wires are disconnected. Batteries should either be charged on deck or removed to an open space in the boat until the operation is completed. The battery box should be well ventilated.
When you're sailing in blue water, keeping your radar antenna spinning all the time really drains a lot of battery power. Now there's a radar tool that helps you to avoid this the Timed Transmit feature, which puts the radar into a standby mode. On your command, it springs to life, scans the horizon, then returns to standby. On Raymarine's C-series, you can select standby periods ranging from three to 15 minutes when the radar is active, you can set i t to make from 10 to 30 scans before returning to standby. This not only conser ves battery power but also keeps the radar's magnetron powered up, so that each time the unit is turned on, it doesn't have to warm up, a process that usually takes 60 seconds. In the Timed Transmit mode, the radar instantly becomes active once the scanner starts rotating.
If your batteries are over two years old or are at all questionable, replace them with new gel batteries. Battery problems resulting from low voltage or fluid levels commonly plague cruising boats. From our experience with Prevailer Gel batteries aboard Mahina Tiare, I do believe the marketing claims that gel batteries will accept a 10-15 higher charge rate so that they can can be charged at a faster rate without overheating or damaging the plates. A significantly lower self-discharge rate means that if left for several months they won't go flat. Another real advantage over traditional deep-cycle marine batteries is that they are totally sealed, and won't leak acid even if your boat takes a severe knockdown. If you seriously enjoy tinkering and playing with electricity, you may choose to go the Surrette or Rolls deep-cycle battery route with a sophisticated charging system that will equalize the batteries once a month. Having gone that route on our last boat, 1 am more happy with the...
We are completely sold on solar power and often go for over a week at anchor relying solely on one panel to run our cabin lights, radio, 12 volt fan, vacuum and sewing machine. Since we've added an inverter, word processor, camcorder and t.v., we've had to run the main engine to charge batteries some times, so it's time for us to think about adding a second panel We have a small Arco (Siemens) M-5 panel which we leave hooked directly to our batteries when we leave our boat unattended. I prefer this to leaving a battery charger plugged in, since there's less chance of overcharging or shorting our with the 5 watt panel. For larger, multi-panel systems, the Sunselector Charge Controller ( 74 64 at West Marine) will prevent overcharging.
