Upwind Sail Trim

Learn the fundamental forces behind upwind sailing as well as nuances of trim to optimize upwind performance.

Sailing efficiently upwind - against the force that drives us - is a marvel of modern design. This North U Sail Trim course provides a fundamental understanding of the forces behind upwind sailing as well as nuances of trim to optimize upwind performance.

Upwind topics include mainsail and jib trim, helming, and a special Trim Solutions section to solve the most baffling problems in upwind performance. The Trim curriculum shows how angle of attack, depth, and twist combine to control upwind power, and how to change trim to improve performance.
