It must be Phill's boat! <img src="http://www.catsailor.com/forums/images/graemlins/blush.gif" alt="" />

If the wind is up around 20-30, you will want to pull the boards up a bit going upwind to keep the hull from flying up too high, drop the traveler a little too, de-rotate the mast for less power, max downhaul, etc.

Going downwind in 20, pull the boards way up, and drive it deep. I have found when I try to go downwind on one hull in that much wind I usually stuff it to the mast and flip, so now I drive deep on two hulls and ease the spinny when the big gusts come. Try to keep your weight as far back as possible and keep the bows up.

I have found swimming to be slower than a flogging spin in a big gust. It's going to be fun in a gybe in that kind of wind! Just let the spin go and worry about it after you have got the main across. Staying upright is more important than a clean spin gybe. Good luck!
