There are a lot of great racing boats. One thing that is important to that decision is what class are you going to race (PHRYF, MORC, etc.). That will have an impact on which boat is better. Another factor is the area that you are racing and the "normal" conditions of that area. Some boats favor heavier winds while others are fun in light winds.Crew size is very important. A good crew is a must for a competitive boat. If you are unable to raise a descent size crew, maybe it would be easier to go with a smaller boat (Trip 26, Melgius, J, etc.). Being short handed can be a big hassle.Another aspect is expense. Buying a race boat is expensive....Maintaining it is very expensive. I crewed on an Express 37 for a while and the owner of the boat bought $20,000 in sails every other year. That is a huge expense along with the odds and ends (things that break during a race and new gadgets that are helpful).The main thing is figure out your budget, figure out the fleet you are racing in, and then go shopping for a boat that matches those needs.
