I too have stumbled upon a 33 yawl for sale and am intrigued. The website link does not seem to have the pictures mentioned on one of the posts. Yawl of America, I have PM'ed you.
There certainly is not much info out there on these boats, if any of you can increase my learning curve, I'd love to hear it.
This boat's engine is accessable the traditional way down below and also the cockpit floor comes up. He says he has no leaking issues. He's also the original owner (1967) and has not sailed the boat in over 10 years. Repowered in the 70's and the engine has only 100 hours on her - so who knows how good the ole memory is.
I sail a Westsail 32 now and the cockpit floor comes up on these too, and ther are definitely leak issues for most Westsail owners.
Look forward to hearing all there is to hear - including ideas on the 'value' range.
