I heard a rumor this morning that it could be a mechanical system that will control the angle of the aero-fairings on the rear beam so they can be used like ailerons on an airplane to increase or decrease righting moment! Before you laugh yourself out of your chair, remember that these boats are capable of (at least) 40 knots of speed over water in 15 knots of wind. That’s nearly 55 knots of wind across the deck of the boat. It is possible to reap some lift off a set of 6’ “ailerons”.
