Stan,
Your post reminded me of our model yacht club in school, nice to know this sort of projects are still being accomplished. Here's my story;
I grew up in Detroit and the Detroit New sponsored a model yacht regatta at the end of every school year for many years. They also published plans for a 24" wooden sailboat built using the "lift method". basically 1" planks of wood glued on top of each other. We had a club after school in the shop and we built theses boats all fall, winter, and spring ready to race them. We made the spars, and you could fabricate the hardware out of brass, or purchase a hardware kit, and sails. These were self steering systems that you adjusted for the wind direction and speed, in relationship to the course, which was a straight course to the other side of the model yacht pond. The boats had 2 1/2 #'s of lead ballast, and we gathered tire weights from the local gas stations and we had a mold that held a U-bolt as we poured molten lead,(in school!!!), to make the keels. Tought us a bunch of skills, and sparked an interest in sailing that many of us still enjoy! I still have my model yacht displayed in our living room.
