A4-1 Asymmetric


The A4-1 is a true all-around performer. It delivers enough power for light air VMG sailing, while still offering excellent control for high speed, heavy air planing. North’s powerful V-Series Asymmetrics are the evolutionary descendants of our dominant America’s Cup and Volvo Ocean Race designs. They have been developed using the University of Auckland Twisted Flow Wind Tunnel and the North Sails Virtual Wind Tunnel™ downwind flow simulation software. The result is a stable asymmetric spinnaker that delivers increased drive and reduced drag over a broader wind spectrum, which is especially important for today’s generation of lighter, faster-accelerating boats.
