I was thinking of learning on a boat, mono or cat, not to exceed 17 feet. I've been told by everyone that learning on a small boat is the best way to go, but everyone has been implying a monohull dinghy. I suspect that using a small cat has not even crossed their minds. Perhaps the folk I have read and spoken to have been biased more towards monos - I just don't know.
I have a Mutineers, Optimists and 420's available to me for free through the club. I can also get my hands on a Hobbie 16 or a Beach Cat 17 anytime for the asking as well. Of course, the number one thing to do is GET OUT ON THE WATER!
Just looking for the BEST way maximize my time.
