Aim for a maximum draft position about 40–50% aft on the sail to allow for gradual, efficient curvature.
Achieving a "deep" sail shape is about maximizing the lift-to-drag ratio and harnessing kinetic energy from the wind. Aim for a maximum draft position about 40–50%
For maximum power when sailing deep, loosen the boom or sprit to create a deeper sail curve. Aim for a maximum draft position about 40–50%
A slightly "hooked" or curved leech can add lift but may cause the boat to struggle if over-tightened. Aim for a maximum draft position about 40–50%
