Steve definately has the ticket for a broach recovery but I emphasize after the broach, BLOW THE VANG, let the main sheet out, as the boat tries to come up, stand up a little, regain some helm, TURN IT DOWN and QUICKLY TRIM THE CHUTE, you're doing 8 or 9 knots again in seconds. Practice it and you'll be surprised how quick the recovery can actually take place.
To me this has always been one of the best charactersitics of our boat, full broach, your feet may not even get wet, you're off and running in a few seconds and may not even loose a boat.
