Rick claims you can roll tack a cat, and I don't dispute that. I sometimes intentionally fly a hull a little high when initiating a tack. That increases weather helm and helps bring the bows up to head-to-wind quicker. In kinetics terms, I am rolling the boat (exaggerating heel by moving my body) to facilitate a tack. Does that count? I suppose, if conditions were right, I could fly a hull coming out of the tack and then hike out to pull the boat back down. That would accelerate the boat out of the tack (the second half of a roll-tack).
