Asymmetrical Sail

For an Asymmetrical Sail, there are 4 measurements required when applying for a certificate.

Asymmetrical Max Girth (AMG): is measured Mid Luff to Mid Leach under moderate tension.

Luff Length (SL or LL): is the distance from the projected intersection of the luff and foot with the luff line under moderate tension.

Leach Length (LE): is the distance from the projected intersection of the leach and foot with the leach under moderate tension.

Foot:  is the distance from the tack to the clew measured in the shortest path on the surface of the sail.
