How Outhaul Tension Changes Sail Shape

The outhaul is a primary mainsail control that adjusts tension along the foot, directly altering draft depth and lower-sail shape. Increasing tension flattens the lower third of the sail, reducing power and drag; easing it deepens the draft for more low-end power. Understanding this relationship is essential for safe, efficient sail trim across wind strengths and points of sail.

How to Reduce Sail Power in Strong Wind

Reducing sail power in strong wind is a core seamanship skill that keeps a boat balanced, manageable, and safe. Key techniques include reefing the mainsail, furling or changing the headsail, and adjusting sail shape and trim. Done early and systematically, it prevents excessive heeling, weather helm, gear failure, and crew exhaustion.
