Here's some other things you may want to think about if you have never sailed a spinnaker cat. First, as soon as you add the spin. buy some good foot straps and put them behind the rear beam, check with others for exact locations but you will need to have something to anchor your self to the boat, steering with one hand and trimming the spin with the other. On windy days, some guys think to fly the spin is "too much" but I can tell you it actually helps keep from pitch-poling because it lifts the bows up, over the waves. Many the windy day I did not fly the spin and regularly stuffed the bows. Then after some more experience, I tried flying the spin on windy days, got my butt to the back, out on the wire, foot in the strap, and it did a wheelie over the waves instead of plowing through them.

I never pitchpoled with the spin up, I did go over but not in a pitch pole type crash but from going too high, to avoid the speed bumps (non-spin boats). You want to be sure to have plenty of room below to bear off when the big puffs hit.

Since you cannot play the traveler, steer and trim the spin all at the same time, set the main and forget about it, work the spin. sheet.

Never ease the mainsheet when it's blowing and the spin. is up, you could break your mast as the spin. will be pulling the tip forward, you need plenty of mainsail leech tension to keep it back.

The only hard part is getting it snuffed at C mark! If it's really blowing, give yourself lots of time and room, you will be busy snuffing, not steering, and do not snuff dead downwind if you have the toilet seat at the end of the pole, the sheets will fall over the front and wrap under the pole, you will never get it all the way in but have to raise it again to do it right.

Snuff on a reach if you can or even with wind ahead of the beam if in light/medium air, that will keep the spin from getting tangled up front.

It's a little scarry the first time in big wind but once you get used to it, you will never want to sail without one again! The speed is very addictive, which is why we are sailing cats in the first place, right?
