OK, so I'm going to give a step by step, I'm sure I'll forget somethign or oversimplyfiy, oh and I'm omitting line placment, because everyone is different, and you can get an idea from pictures from hobie like the previous poster said.(I just use a simple line the wraps around mast base, then tossed over top hull, its tied to dolphin striker, which you might not have)

1. be quick, must not let boat turtle(you should be fine if your mast doesn't leak)
2. stand on hull in water, move weight to bow until bows points into wind
3.Uncleat sails
4. lean back on righting line, as mast rises wind will help push it up by getting underneath the uncleated sail
5. As boat comes down grab eigther dolphn striker or front beam
6 boat should be headed dead into wind with you hanging on front beam in between hulls
7.climb on and away you go


if your new to cats but know some about sailing, then I do suggest Rick White's book Catamaran racing for the 90's Its not just for racing and this technique, along with several other useful techniques are described there.

Also this is not a stupid question, I think this is one of the most important skills in sailing. Its a saftey issue, you might try practicing this in shallow water untill you know you have it down.

Happy sailing on your new cat!
