Learn to sail first
Don't start with what boats are available: start with what you need, then find the boat that fits. There are plenty of boats out there, waiting to be bought.I'd suggest you begin by thinking back over those sails with friends: what you enjoyed most, what you enjoyed least. Maybe a slow forgiving boat is just what you need; maybe you'd prefer something fast and exciting. Maybe 23 feet is too small for you, maybe too big. (I think you'd learn a lot faster on a smaller boat.) If you don't yet know what you need:The best way to learn is to take a course at a good school. It gives you another way to think about boating: how it feels to be in charge of a boat, and what aspects of that appeal to you. It could also open up the option of renting boats for a while before buying. If it were me, I'd definitely take my lessons first, then start thinking about shopping.Dick
