Re: Another America’s Cup entry destroyed

Where did this concept that wing sails can't be de-powered come from? A sail generates lift (gets its power from the curvature of the outer surface) a wing sail has the ability to be flattened more than a traditional sail. Thats how they get a semi solid surface to function on both tacks. They have the ability to bend the wing in an indefinite number of positions adding more or less power, on each tack. that also gives them the ability to leave the wing virtually flat on both sides and effectively powerless.
