need to model the interior. Using the drawings I built a master with a wooded core and styrene keel and gunwales. Even though these boats required rudders I did not include them as they normally were stowed inside the boats when not in use. I did include the pintles and their straps. Photos 379 and 380 show the master without the pintles. T e imperfections of the prototype were not pronounced enough to include on the master. Nevertheless, I kept some slight imperfections in the texture of the master’s hull. A two-part mold was necessary. (Photos 381 and 382) T e sheer of the gunwales required the top of the mold to follow this curvature, so, when I poured the lower half of the mold, I had to fi ll the space above the sheer line with molding clay. I also fi lled the

corners of the mold wall to minimize the amount of mold rubber required. (Photo 383) Notice that the top of the mold has holes through which excess resin could escape when the top of the mold was forced into the bottom. Photo 384 shows the resultant copy and the cradles being prepared for attachment. T e copies were solid, which consumed a lot of the resin, but, in this case, my supply was aging and needed to be used up.

One of the diffi cult things to reproduce well is boat canvas covers. My solution, though not perfect, worked well. Photo 385 shows one of the lifeboats resting on its cradles and covered with Saran wrap. T e ridgepole supported the cover to prevent water
