Please note that the side fins only work well for Witchcraft boards or boards with the side fin boxes placed under a 2° toe-in angle to provide the least drag and best turning behaviour. The correct toe-in angle is essential for fins to work properly. With a 2° angle there should be 6mm difference in distance between the Minituttle side fin boxes, measured between the fronts and the backs of the boxes.

SR Fins

For boards from other brands which still have the boxes paralel or less than 1° toe-in angle we offer our pre-twisted fins as SR fins. These fins have less drag and turn better so you can choose bigger side fins and a smaller centre fin. It is recommended to combine them with Witchcraft center fins. For example for a 86 to 96L trifin wave board, you can use 13.5 side fins and 14.0 centre fin. Everything will become loads better: Better turning, more speed, more control and better up wind. For a Quad between 86 and 96L you can use for example side fins of 11.5 or 12.5 and 12.5 or 14cm trailing fins.
