When Kai Hopf, (North Sails designer) and Pio Marasco get together you know they are going to come up with something high performance! Both Pio and Kai have been designing windsurfing fins for more than twenty years, and together they have developed the fastest racing fin ever. The thin profile and custom flex pattern is possible with CNC shaped G10. This gives you early planning and lots of speed. Designed to avoid cavitation at very high speeds, you will have the confidence to push your gear to new PRs on your GPS. The black pigmentation of the G10 is absorbed by the resin to help create a very smooth surface that helps increases speed.
