....a flexible wedge of foam integrated into the top of the sail to give it thickness, like padded sails were. Then it would contribute no additional drag.
I don't get that. If you make the top of your sail fat and symmetrical, wouldn't you lose some drive out of it and also cause some drag?
I'm not sure I understand the "wedge" thing and which-a-way it is pointed or placed in relation to the sail.
I am just interested in all this stuff because I would like to see something invented that would be practical for people to use for safety reasons and at the same time be acceptable to the serious racers -- the bob snobs.
