Distance racing did it for me. I was ground crew for Team SanDiego in the 03 Tybee and got a chance to know the boat a little more with working on it so much.
I had a 21SE at the time and tried to do some distance racing with it (04 GT300) but the LeMans starts are a bitch with a 700 lb boat. I ended up "pimpin' it out" enough to sell it and get a N20. First sail on it (late 05 or early 06) was my first time on a N20 and I almost fell off because it steered so quickly (used to a real heavy helm on the Hobie and balanced myself with it more than I realized).
Aside from updating the sails, I wouldn't change a thing about it.
