Think breeze, if it doesn't blow you won't want to go out. A number of fast boats are also boats that are a lot to handle in a breeze over 15 knots. I have raced Melges and they are a handful for 2 in a fresh breeze, especially whhen you fly the A-sail. Most class (fast) boats have web pages with listings of local clubs. Why not see if some boats are in your area and go down to the club and crew on a boat that interests you.
good plan to "try before I buy" - what I'm having trouble with is coming up with the list of candidates, so that I can track down the local fleet.
