Those Castro boats are good looking by any standard. And they sail well. What's not to like?
Hey.. don't get me wrong.. I feel extremely fortunate to have such a great boat. She's not perfect, but she sure is fine...
Back to the subject, sort of...
I think few people will deny (well, I can think of one) that the development of GRP boats has created a revolution in the world of sailing, with ordinary folks became able to afford to own and maintain sailboats, to a level that wasn't generally possible before.
In the mid-sixties, my father, a machinist at General Motors, was able to buy, maintain, and sail a boat (Shark 24) large enough to take my mother and us 4 kids for weekend sails in Michigan.
It was something he could afford to do, and maintain the boat without special skills!
We are all lucky to live in such a time.
