High-performance boats (like America's Cup foiling yachts) go so fast they create their own gale-force winds, allowing them to sail much faster than the actual true wind speed. 4. The Center of Effort vs. Center of Lateral Resistance
If the sail’s force is too far back, the boat will naturally want to turn the wind (weather helm). Physics of Sailing
As a boat speeds up, the wind "shifts" toward the front of the boat. Physics of Sailing
The boat "squeezes" between the wind’s push and the water’s resistance, converting that sideways energy into forward motion—much like a wet bar of soap shooting out of your hand when you squeeze it. 3. Apparent Wind Physics of Sailing
