St Thomas Sailing Center Director Dave Franzel managed to capture team Bergquist, one of the top-ranked women’s match race teams in the world, demonstrating roll jibes and roll tacks. Notice how letting the boat heel after the tack stops the boat from turning without requiring any rudder and how flattening the boat after it stops turning helps the boat accelerate. Notice too how rolling the boat to windward prior to a jibe turns the boat towards a jibe, again, without requiring any rudder. Flattening after the jibe stops the turn.
