Elvstrøm Sails 1A asym. spiler

Elvstrøm Sails 1A Gennaker

The A1 is a sail for lighter winds and for when you are sailing higher angles. Typically you are forced to heat the boat up and sail angles between 100-135° TWA in wind speeds between 4 and 9 knots. You may also be on a leg in an offshore race that gives you these true wind angles. In 4-10 knots of TWS you will benefit from the A1 with its narrow top angle and the reduced mid girth. The sail simply drives the boat forward better at those angles. Size factor: 78% of A2.
