Fin Selection Tips

Longer fins provide more lift and upwind capability, making them ideal for heavier riders or underpowered conditions. Shorter fins offer quicker release and are better for maneuvers. A general rule: add 1cm per 10kg above 70kg body weight.

G10 (fiberglass epoxy) is durable, affordable, and forgiving - great for recreational use. Carbon is lighter and stiffer, providing better response for racing and advanced riders. Carbon fins are more fragile but offer superior performance.

Anti-weed fins are designed for spots with seaweed, grass, or floating debris. They feature a special leading edge that sheds weeds while maintaining performance. Essential for shallow water spots or areas prone to vegetation.

Check your board - Deep Tuttle (65mm) is common on freeride/slalom boards, standard Tuttle (43mm) on smaller boards, Powerbox on entry-level boards, and US Box on wave boards. The box depth affects stiffness and performance.
