All-Purpose

The North Viper 640 spinnaker reflects the knowledge we've gained by designing winning sails for a variety of sport boats. Our sail is sized to be class maximum and twists and rotates well, so you can sail lower angles while going the same speed or faster. For additional colors, please contact your local North Sails loft or agent.
