I wish my HS had a sailing team! But I agree with what Rolf said. Perhaps the mono sailors are not interested in catamaran sailing because it involves the more technical aspect of the sport. I know that when I learned to sail on a mono, it was always an easy to transport, easy to rig, easy to sail boat. (sunfish) This is probably why this boat is one of the most popular in the world. For this reason, I fully support all the work that the F12 guys are putting into developing that boat. Without simplicity, you lose 80% of your sailing crowd. People who are used to hopping on a boat and going are not going to want to learn all the skills and techniques involved with cat sailing. Perhaps I am wrong, but I support developing a simple cat, and once you get kids hooked on that, move them up to an A, or F16, F18, Tornado. ISAF will see that the catamaran community is sincerely putting forth an effort to change the decision by taking action, and this could sway them to change the decision.
