Changing the fins on a fish surfboard can dramatically change the feel and the performance of the board. The three most common types of fins for fish surfboards are twins, thrusters, and quads. Let's see which fin setup is best suited for your style and surfing requirements.
The fin, or fins, underneath your surfboard are there to help with the steering of your board. The fins will also assist with stopping the surfboard from sliding around on the wave. The further the fin goes down in the water, the more control you will have over the surfboard on the wave. The shorter the fin, the less resistance there will be on the water. The longer the distance of the fin where it is attached to the base of your surfboard, the faster you will be able to go.
