Sarah, If you are in Boston this Summer, do contact Barry! He is one of the best contacts you could have for cat sailing in New England! I don't know of any FX Ones in Massachusetts, but there are probably some Nacra 17s. If I have the time, I'd be glad to get you out on my Hobie 17 Sport conversion. It is a fast fun solo boat, but due to the mods can't be raced except in open class. It is a great old boat, and would probably serve you well if you don't have big waves/chop. Check out Team Goose under groups, in Catamaran Pictures at www.thebeachcats.com . Come on down to Gooseberry. Most folks have older Hobies, but sometimes there are some Nacras. Barry has been known to make an appearance for The Island Hop. Check out www.fleet448.org too! We love to welcome enthusiastic new sailors to the sport of cat sailing! I think you are in for a lot of fun no matter which of the boats you choose!
