Only in rare occasions such physically different windsurfers became so intensively involved in the development of a single sail as was the case with Björn Dunkerbeck, Gollito, and André Paskowski. After all, no other sail can cover the entire range from wave to flatwater Freestyle as perfectly as the new Duke.

The requirements for a Power Wave and a Freestyle sail are very similar: great planning potential combined with maximum handling and good controllability. The Duke was therefore designed as a powerful wave sail according to Björn’s specifications. Since it possesses the greatest trimming versatility of all North wave sails, it can also be easily controlled by medium-weight sailors. The use of stable X.PLY 725 in the centre panel of the small Duke increases durability, leaves room for reserves, and underscores the suitability of the small Duke for waves.

For sizes 5.9 and above, Kai Hopf improved the new Duke strictly according to the specifications of our Freestyle World Champion Jose “Gollito” Perez and EFPT Champion André Paskowsky. All Duke models are made to suit SDM masts, which ideally fit this type of a more direct sail.
