The leeward side of a sail is the side that is convex as opposed
to the windward side which is the side that is concave.

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.
Faster flow equals lower pressure. This low pressure combined
with the normal or slightly increased pressure on the windward
side is what creates lift.

A very naive explanation of how a sail works, indeed!
Why igore what happens on the leeward side of the sail?


OK Cappy, you dropped the hint, now tell us what happens on the
leeward side of the sail....first you'd better explain which is the
leeward side!
