For the style of sailing you wish to do I would look into a Maine Cat 22. I'm not sure if they are being made anymore, but they would be perfect for the sailing you want to do. However, the size may not fit your garage, and the price may not be very low. It is trailerable (hinges in the middle). Also look for old Cougars, they came in wood and fiberglass, obviously you'd probably want the glass one. Not too common, but you might be able to scare one up.
