Sail -

Use telltales on both sides of the sail; ideally, they should be parallel and flowing backward to confirm laminar flow. Preparing For The Storm : How to Lie A-hull

For maximum power when sailing deep, loosen the boom or sprit to create a deeper sail curve. Use telltales on both sides of the sail;

To "sail deep" refers to a specific technique in sailing where a vessel maneuvers as far downwind as possible, typically to maximize efficiency or to safely manage sails like a spinnaker or furling headsail. Preparing for this requires a combination of technical sail shaping, rigorous equipment checks, and an understanding of the physics that keep a boat stable when running with the wind. 🌬️ Technical Sail Preparation Preparing for this requires a combination of technical

Aim for a maximum draft position about 40–50% aft on the sail to allow for gradual, efficient curvature. rigorous equipment checks

A slightly "hooked" or curved leech can add lift but may cause the boat to struggle if over-tightened.
