Racing Asymmetric Spinnakers

North’s powerful Racing 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. North Racing Asymmetrics are offered in six different wind range models, each with a targeted selection of high performance downwind materials to precisely match your boat and type of racing.

  • Some colors may not be available at the time of order
  • Please select the material type based upon your sail quote or sales order information
  • Three colors only – to avoid dissimilar material properties
  • North Sails is not responsible for sail shape or smoothness issues related to color combination

Color Schemes

  • Available Color Schemes are based on size. Please choose from a pre-existing scheme based on your boats I or ISP dimension (Spinnaker Halyard elevation from deck) .

Color Variation

  • Spinnaker materials vary in color between styles, lots and cloth weights. Your sail may have two or more cloth weights which will be noticeable in the finished sail.
