Channel Islands Gudauskas Surfboard Fin Set

This configuration offers the loose, fast feel of a twin-fin while adding a small center trailer fin for extra stability and control. It is ideal if you want the speed of a twin but find your board feels a bit too slippery or unpredictable in critical turns.

These fins use a standard 2+1 configuration. As long as your surfboard has a three-fin box setup, they will fit, though they are specifically designed to enhance the performance of twin-fin boards that have a center box for a trailer.

The narrower base reduces drag and allows for quicker, more fluid transitions from rail to rail. It helps the board feel more responsive and 'pivoty' rather than locked in, which is great for tighter turns in the pocket.

While these are primarily performance fins for everyday conditions, the added trailer fin provides enough hold to handle moderate surf with confidence. If you are surfing heavy, overhead waves, you might prefer a dedicated thruster set for maximum grip, but for most conditions, this setup offers a great balance.

This template is built for a skate-inspired, high-performance approach. It encourages you to draw tighter, more vertical lines and allows for quick, snappy maneuvers that a traditional twin-fin might struggle to maintain control through.
