North Downwind Sail Performance Guide

V-Series Asymmetrics
V-Series Symmetrics G-Series Gennakers
AWA = Apparent Wind Angle     TWS = True Wind Speed
Values presented in this sail performance guide are approximations intended for relative comparison. They are based on experience and observation and do not represent specific test data. Variables such as individual boat performance characteristics and sailcloth selection will have an effect on apparent wind range and apparent wind angle. V-Series styles are available in woven Nylon or Polyester fabrics. Specialized reaching sails are also available Polyester and Aramid laminates or Cuben Fiber. 3D thermo-molded construction may suit some specialized applications. G-Series Gennakers are not legal under many handicap racing rules. A variety of Roller-furling systems are available for most V-Series Asymmetrics and G-Series Gennakers.
All North spinnakers have been developed using Virtual Wind Tunnel flow simulation software
