The Crossbreed 11’ inflatable SUP, which we have all come to love, now doubles as the perfect board to learn how to Wingsurf. The removable sUP WINDer keel fin, combined with the normal tail fin, will allow you to stay upwind while using a wing and propel you across the water. Of course, you can use it without a wing, too! This stand up paddle board from Slingshot is the perfect board to dip your toes into wingsurfing. The SUPwinder fin is detachable so on windless days, this 11ft paddle board performs with excellent rigidity, speed and durability.  Whether you are looking to upgrade from a single layer board for yourself or getting this as a family board - you won't be disappointed.
