sail trim

Sail trim involves adjusting a sail’s position and shape to maximize efficiency and control of a boat’s movement. By changing the angle of the sail relative to the wind (called “sheeting in” or “out”), and using controls like the boom vang or outhaul, sailors optimize how wind flows over the sail. Proper trim helps increase speed, maintain course, and improve handling. Factors like wind strength and direction influence trimming decisions. Well-trimmed sails generate more lift from the wind, propelling the boat smoothly and effectively.
