I was thinking of the same thing as Wouter. Go crew for a year or so, before you buy. You'll figure out what you like in a boat, and what you dont like. Owning a boat is a lot of work and picking the wrong boat is a painful experience.
Whats the old saying?
The only thing better than owning a boat is having a close friend who owns a boat.
Good crew is usually in short supply - at least thats been my experience.
If you learn how to crew and make a bunch of connections with people that need crew it will give you a chance to try out new boats before you buy one.
