Ayrodynamics of Sailing
It''s a snap.
1. Point the boat where you want to go.
2. Let out the sail(s) until they flap a little.
3. Pull in until they just stop flapping. Don''t pull in any more.
4. When you change direction, repeat 1-3.
You won''t win any regattas like that, but it''s good enough for now. Sailing is a simple thing.
