H1 Racing G10
This a cooperation project between Kai Hopf, Duotone windsurfing Sails designer, and Pio Marasco. Both Pio and Kai have been designing fins for more than twenty years, and together they have developed the fastest racing fin ever. Made from CNC shaped G10 with a very thin new profile and custom flex that provides early planning and lots of speed. This new profile applied was designed to avoid cavitation at very high speeds. A new colouring material for pigmentation of the G10 that is absorbed by the resin has been used creating a very smooth surface that helps increases speed.
