Code Zero

A large, light-air reaching sail with an asymmetric shape, typically set on a furler ahead of the forestay.

A Code Zero bridges some of the performance gap between a genoa and an asymmetric spinnaker. Its cut, luff tension and permitted dimensions vary between cruising designs and rating-rule definitions.

It is not always a close-reaching sail and may be designed for broader angles. Tack loads can be high, so the bowsprit or attachment, halyard, furler and rig must be approved for the sail.

Beam Reach

The wind is coming across the side of the boat. This is usually quick, stable, and easy to feel.
