Along with the other great advice, get a book called "sailing the Farm" for sustainable grub while away. I started with a 27' Catalina
(1972 model) and after a fit of foot-itis got a 43' Bruce Roberts
. Lived for several years on both and realized more room = more crap you really don't need. The Catalina
was put under extreme stress many times and though I had my moments of doubt, the damned thing pulled me through. If I were single
again, I would look hard at a 27', but I don;t know about the construction of new boats. Very pretty at the shows does not count in 50+ knots with 25' seas, and less room in the salon
means shorter distances to fly through the air before hitting something hard.
Look long and reduce your cargo, then do it again. Then look hard again.
Best of luck,
