Reading the Drawings by Mike O'Brien

/h an attempt to represent three-dimensional boats on two-dimensional pieces of paper, designers resort to four basic drawings: the sail plan (or profile), accommodations (or arrangement), hull lines, and construction. Inexperienced eyes seem to view hull lines as being the least accessible of these presentations. In truth, reading the drawings isn't difficult. Once you learn the tricks, the lines will float from these pages as fully formed hulls.

Boat design used to, and sometimes still does, begin with a wooden model of a hull. Imagine, if you will, taking such a model and slicing it as a loaf of bread (see Figure 1). Working to a common centerline and baseline, trace the outline of these slices or sections on a piece of paper. The resulting drawing (inset, Figure 4) gives a picture of the hull's shape as seen from the bow or stern. Usually, the designer shows only half: of each section — relying on the builder's inherent sense of symmetry to produce a reliable mirror image. All of the half-sections are presented in a single drawing, the body plan. Most often, the right side shows the hull as if it were coming at you. The left side represents the view looking forward from the boat's wake.

In your mind's eye, reassemble the wooden model. Slice it again, but this time cut the hull horizontally into layers (Figure 2). Trace the shapes of these slices (waterlines) on paper about a common centerline. This drawing shows the hull as seen from below (Figure 5). You should look at it much as you would study a = contour map.

Once again, put the model together with imaginary ; glue. Run your make-believe saw vertically and Ion-gitudinally through the hull (Figure 3). The shapes revealed by these cuts are buttock lines, and they can be traced as were the other lines (Figure 4).

Reading the Drawings

All of the lines described above appear in their own drawings as curves. They also show up in the other drawings, but they are seen there as straight lines. That is to say, the sections display their shape in the body plan, and appear as straight lines in the elevation (profile) and waterlines (half-breadth) drawings. The shapes of the other lines in various views should yield to study of Figures 4 and 5.

Although the three sets of lines we've discussed define the shape of a hull, designers almost always include a fourth set. Diagonals emanate from the centerline in the body plan as straight lines that intersect the curved section lines at more or less right angles. And therein lies the key to the diagonals' value. Nearly perpendicular crossings provide the greatest accuracy for fairing a set of lines, whether on the drawing table or, at full scale, on the loft floor.

Blue Moon

Designed by Thomas C. Gillmer

In these specially labeled drawings of Blue Moon's hull lines, the sections are marked with Arabic numerals in all views. Note how they take on shape in the sections drawing or body plan. In the other views, the sections appear as straight lines. Similar reasoning can be applied to the waterlines (upper-case letters) and the buttock lines (Roman numerals). Lower-case letters mark the diagonals in the body plan.

How To Have A Perfect Boating Experience

How To Have A Perfect Boating Experience

Lets start by identifying what exactly certain boats are. Sometimes the terminology can get lost on beginners, so well look at some of the most common boats and what theyre called. These boats are exactly what the name implies. They are meant to be used for fishing. Most fishing boats are powered by outboard motors, and many also have a trolling motor mounted on the bow. Bass boats can be made of aluminium or fibreglass.
