I have two boats
Hobie 14, it was cheap and is a blast to sail in heavy wind.
Nacra 5.2, My baby right now, she makes a great single hand boat with the ability to take a few people out on it. Also it is fast and pretty competetive for how old it is.
I am planning an upgrade in the next few years to another single hand boat that can carry two. The FX-1 looks cool but I also like the Inter 17, and alot of the F-16's.
