Unifibre Weed Slasher G10 (black) 28cm / 30cm / 32cm / 34cm / 36cm / 38cm/ 40cm - Tuttle Box New The Unifiber Weed Slasher G10 is a fin that is specifically made for windsurfers who windsurf in waters with loads of weed in it. The Weed Slasher has its shape to the rear but the fin more to the front compared to the box. By doing this, Unifiber has succeeded in delivering the performance of a 'normal' fin and still making it an weed fin. Thanks to its profile, the Weed Slasher provides control and comfort while sailing. https://www.youtube.com/watch?v=wUu70whH34E
