My Sidecut Design has been developed over the last 20 odd years or so and allows you to follow the natural arc of the turn with added bite and hold. This happens by having more rail in the water as the sidecut engages, allowing the outline to fully slice through the turn and feel resistance free. The concept is the same as a snowboard arc-simple yet effective. The sidecut can be adopted into my fish outlines as well as my rounded square or squash tail outlines. Fin setup on these is either my low profile long based keels, my specialised quads or my thruster mini keels by True Ames.
