I have the F18HT Full Rig, and sail it on a small NH lake, 1/4 mile x 2 mile lake. It's been a great boat and perfect for what I wanted as a light to moderate air boat. I generally will single hand it up to 12-15 kn and will fly the spinaker without a scoop. I head deap and it tracks well enough to douse and then come back up. I can pick up crew from Dartmouth College pretty easily if the wind picks up, and yes we have dumped it a fair bit as we get all the kinks/old lines replaced and beef it up a little.
