It depends on the vessel and how it is rigged
In my years of Sailboating in the Waters of the Florida Coast I have found that the best sail to use would be a circular sail painted blue with pink polka dots
No one can say who, where or when the first sail was made. Consequently its shape is not know either.
diamond
the shape dose effect it.
"Asymmetrical" is a description of the shape of the perimeter (outline) of the sail. It just means that it is not symmetrical.
The name pretty much specifies itself, a sail in the shape of a triangle. lol.

The best location to sail in Second Life is the lake area in front of Caddo.
Yes, It depends on the speed but it slows it down.
the difference is the shape
It depends on what class of boat, what mast and boom you have and what amount of wind you sail in.
