US Box Fins originated in the surfing world where they are widely trusted to do a great job. A number of Red Paddle Co boards boast them, including all of the Race Family as well as the WindSUP and WindSURF boards. We use several different types of fin depending on the board. These fins are inserted after inflation and simply attached using a simple nut and bolt system. The fins are specially engineered to slice through the water and the Race fins have a 45% rake on them to ensure no weeds get caught which could slow you down.
