S4 SPINNAKER

North’s powerful Racing Symmetrics are for racing boats equipped with spinnaker poles. They have been developed and refined using the University of Auckland Twisted Flow Wind Tunnel and the North Sails Virtual Wind Tunnel™ downwind flow simulation software. The result is a versatile symmetric spinnaker that delivers maximum power and minimum drag. North Racing Symmetrics are available in six different wind range models with select, high performance downwind materials to precisely match your boat and type of racing.

North Sails offers a wide variety of downwind symmetric and asymmetric sail types made using the NPC DOWNWIND sailcloth range. Each of our sail types is designed for a specific range of wind speeds and angles. Every North spinnaker is custom designed to suit each customer’s needs and maximize VMG/VMC in the broadest range of wind and sea conditions. NPC DOWNWIND sails provide higher boatspeeds, deeper angles, and faster acceleration with consistent and predictable trimming characteristics.
