These plans are for a small sail boat called the Biloxi Dinghy. Former builders claim it's a great design.
From the plans:
Here's just what prospective builders of small sailboats have been looking for, as you will see from a glance at the facsimiles, which reproduce excerpts from letters written by enthusiastic owners.
And, the Biloxi Dinghy is not only seaworthy, as they say, but it's easy to build. Look over Figs. 1 and 2, which detail the frames and stern board, or transom. There are several points to keep in mind before you begin cutting the parts: The lower cross members of all frames are cut to the same radius; the top crosspieces are a given distance above the lowest point of the curved member, and the frame uprights are joined to the curved members with an angle joint housed in gusset plates, as in Fig. 2. With the frames, stern board and building board made, the work on the hull is well along. You start assembling the boat by placing the building board on two sawhorses as in Fig. 3. The lines marked on the building board, Fig. 4, indicate where to place the frames. These are placed upside down and the center line of the building board must match up with that on the frames.
After all three frames have been attached to the board, the next step is to fasten the sides to the stem, Fig. 6. This can be done before mounting the stem on the building board although it is shown mounted wtih the frames in Fig. 3. If the sides are built up of several pieces, you simply screw the two lower planks to the stem, but should the sides be made up of narrow planks, the first plank on the lower side should be at least 8 in. wide. When building up the sides you can use shiplap construction which will eliminate battens...
