Could someone please explain to me the finer points of sail trim--and the aerodynamics involved--of motorsailing? Am I correct in saying that motoring creates apparent wind which, as it flows past the main, establishes low pressure on the windward side of the sail so it is helping to pull you forward? If you have no wind other than apparent wind dead on the nose, how do you establish what is "windward," and how do you trim the sail?

thanks all
