C-Series Roller-Furling Gennakers™
Roller furling Gennakers for racing and cruising boats

North’s new C-Series Gennakers combine superior close-winded reaching power with the convenience and easy handling of roller furling. Descended from tight reaching asymmetrics used by Volvo Ocean Race and Open 60 competitors, C-Series Gennakers are a more user-friendly version designed specifically for cruisers without the restrictions of handicap or racing rules. They have been refined using the University of Auckland Twisted Flow Wind Tunnel and North’s remarkable Virtual Wind Tunnel™ downwind flow simulation software. The result is an easy-flying Gennaker series that will boost your reaching performance when apparent wind is forward of the beam.

C-Series asymmetrics feature North TrueRadial™ construction, which shapes spinnaker panels on two axes for a smoother profile both vertically and horizontally.

Your North Sails representative will assist you in selecting the roller furling system best suited for your boat, budget and sailing style.
