Michael.. I embedded your pics using the IMG code instead of the URL link.
Chartruese,, maybe downsize those pics a bit??
Took me awhile to dig these old pics up.. some 26 or more years back a friend and I decided to build our own dinghy, so we started out with making a female mold.. the first hull 'stuck' so it became the plug for a new all glass mold, after which hulls 2 and 3 were built ending the production run. All three boats are still around.
These projects cost more in sweat equity than anything, along with a steep learning curve but our boys learned to row and sail in them. My buddy still has his, we sold ours some time back. Hull #1, about 10 lbs heavier, is still around too. This was my own design, an attempt to split the difference between an Opti and a Sabot...
The first wouldn't have cost more than 400 in materials and we all got our money's worth by the time we were done. (btw this little guy turns 31 in a few weeks
