V-Series Symmetric Downwind

North V-Series™ spinnakers have won more races than any spinnaker design in history, not only because they are fast, but they are easy to fly. V-Series spinnaker panels are computer molded, both horizontally and vertically, creating a profile that is exceptionally smooth.

The result is a shape that creates a smoother and more stable wind flow over a broader wind range, which is especially important for today's generation of lighter, faster-accelerating boats. It is also beneficial to boats racing under IMS and many offshore one design class rules which limit spinnaker inventories.
