Re: Thinking of buying a new boat
I've no experience buying used boats, but i do know about getting into sailing with no experience.
Take a boating class, so you learn the 'rules of the road'.
Think about writing a brief document that explains how the boat buying partners would unwind.
I'd suggest buying the newest, best maintained 30'+ boat you can afford.
You've crewed. That's good. Buy a sailing book. Something like: Sailing for Dummies.
Hire a captain to accompany you from where it is, to where you'll keep it. Hopefully an overnight trip away. Get him to show you how to operate the boat's systems and offer sailing advice.
Regarding marinas....my advice is to find an inexpensive yacht club that has reciprocity with others. Picking up a mooring ball and visiting other clubs is tons of fun.
Sailing is fantastic on Long Island Sound. Have fun.
