Philip is right. Having X dollars split amongst 2-3 boats means they are all slow usually. Unless X is a large number and you can afford to pay others to do maintenance. Keeping more than 1 race boat in inventory is very $$ for all but the pros, not their dollars.

F18 is a great class right now because buying new parts adds appreciation to your boat. See that N20 listed for dirt cheap with a $4K set of sails? Yeah glad I sold mine when I did, even though it's still one of the best boats ever built.

That's the thing, I can't afford to keep the F18 fed AND X foiler fed. So I'll be the last to switch unless I win the lottery.
