Full carbon Harmann surf foil with 2 US Mount. It also has a deep tuttle adaptor if needed. Mast is 80 cm , front wing wing is 1360 cm2. I bought it new about 18 months ago and had a few attempts, but it looks like it doesn't match the board I have. It has been sitting in the garage for months and I think I will stick to my conventional windsurfing.
