The convex side of the sail or the leeward side directs the air
over a longer path. This longer path for the air lowers the pressure
because said air must move faster to cover the increased cord.
Shouldn't that be "chord"?
Yea man!
The chord is a straight line, not the curved part that the air moves faster
over.
