Re: I've never sailed in my life... talk me into it.
The best advice so far is to look into clubs, lessons, and shares. You'll get experience, make sailing connections, get to sail on different boats, and figure out what you do/don't like. Then you're already sailing, the pressure to "buy now" is off, and you can wait for the right deal at the right time.
As far as talk you into to... I can't do that. The wind either calls you, or it doesn't. If it doesn't no amount of cajoling will talk you into it. And if it does ... nothing can talk you out of it.
