Sweetheart, don't listen to the haters. I've owned over a dozen boats and currently own three. The largest being just a tad over 50'.
If you dream of a sailboat don't wait, buy a little 25 footer with a nice head, galley, and cabin (a Catalina 25 or 27 would be perfect). You can pick up a boat like this for 5 to 10K. You can easily put an a/c on the forward hatch and keep it cool all summer long.
Rent a slip in the nearest marina and tell the local sailing dudes you want to take it out but need a little help. You should have fights breaking out for the privilege of teaching you. It'll be more fun than you can imagine.
