That's one of the problems with the H17. You'll do it easily with roll tacking. Get Rick White's video on tacking and you'll see how easy it is to keep the boat speed up through the turn. Couple of tricks: Keep weight to rear as you turn the rudders (do not jam them); When the boat is directly in the middle of the turn, loosen the mainsheet about a foot; when the boat is on the new tack, get your weight to the windward side and up towards the front crossbar. Slowly, trim the main again.
