All sail have their drawbacks the thing is sails aren't wings as Bertrand has shown the perfect sail shape is a D the problem then is swapping the shape from one side to the other as you tac, Bertrand came up with a battened Junk sail that folds in the middle, the mast in each hull works better as it's like stacking foil kites, the problem is you're going for height in your sail not width the most powerful sail is the spiniker not because it's any taller than the others but because it's wider.

Swapping a large sail over doesn't work either, the solution was solved by the Vikings, they sailed all over and were able to fight when they got there; how by having double ended boats and a wide sail on one side see;Ship Theory, how did they tac ? See;harryproa/ Shunting Diagram
