The HS 2+1 fin is unique and versatile and has been specifically designed for use with the Haydenshapes Plunder model. The Plunder can be ridden with only the HS 2+1 center fin, which gives the fin a good flow and a lot of turning pleasure during the curves. To generate a little more speed, the fin can be used in the 2+1 setup, which gives the board a mixture of thruster feeling and classic single fin feeling.
