When it's "pitchpole probable" conditions, I have my boards up a bit, the windier, the more up, and then I can brace myself from sliding forward by putting my front foot up against the back edge of the uprasied board (booties on of course!) and my rear foot is hooked under the hiking strap. I toss the tiller extension out back and use the tiller arm to steer, not the crossbar, bent too many already!

The best way to prevent the pitchpole however is to be constantly looking back for the next big gust and bear off -before- it hits, loads up the mainsail and starts the bow going under, because once that bow goes deep, you're toast, even faster if you slide foreward when you first stuff the bow. If you can stay at the back, bear off and ease the spin sheet, you might save it....or not. But I have found going lower/slower on two hulls vs. higher/faster on one to be the safer option in big wind.

I've been able to get it skipping on top of the waves by 'going ugly early' on two hulls when the big gusts hit, but you have to keep those bows up and your weight back.
