Mondo Knows Facts
Sailboats cannot sail straight into the wind
A yacht heading upwind must tack, turning through the wind in a zigzag A sail works like an aircraft wing, generating lift from air passing over its curved surface, and it cannot do this inside a narrow dead zone directly upwind. The crew sail as close as about 45 degrees to the wind and then turn through it to the other side. Each tack costs speed, so choosing when to turn is a tactical decision. It sits in Mondo's sports collection, one of 200 facts that each trace back to the reference below.
