Should you decide to make a model of your own boat, perhaps my experience will inspire and instruct.
To begin, I purchased plans for my Nonsuch 260 from the designer. I had planned to use a 1:12 scale, and fortunately, the plans were drawn to this scale. I decided to make the hull from fiberglass laid over a foam mold. I copied the station lines, one for each station, on to card stock, which I then carefully cut out with scissors. These were then glued to blocks of urethane foam the exact thickness of the distance between stations, the bottom edge of each station exactly in line with the bottom of each block of foam. I glued the blocks of foam together in sequence on a flat piece of plywood, but not to the plywood, then shaped the foam by sanding until the sandpaper just touched the card-stock stations and the surface between stations was fair. Over the foam, I applied six layers of 6-ounce fiberglass cloth using epoxy resin, which, when cured, I sanded smooth. Imperfections were filled with epoxy putty, then sanded again. WEST System literature provided complete guidance about the epoxy and fiberglass I used.
