Practical Knowledge for Life Under Sail
Recognizing an approaching squall is a core seamanship skill that combines visual observation, weather data interpretation, and an understanding of local conditions. This guide explains the key indicators, practical steps, and common mistakes to avoid when a squall is bearing down on your boat.
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.
