North’s powerful V-Series asymmetrics are 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 North’s remarkable Virtual Wind Tunnel™ downwind flow simulation software. The result is an 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.
North V-Series Asymmetrics are available in seven different “codes” designed to precisely match your boat and type of racing. North’s A2 and A4 runner molds, for instance, are larger and fuller than the A1, A3 and A5 reachers, and carry maximum girth higher up in the sail. This helps rotate the sail to windward, out from behind the mainsail for improved performance at the deeper wind angles commonly sailed in windward / leeward courses.
