FCS Mid Carver Thruster Fins

These fins use the FCS II system, which is designed for tool-less installation. Please ensure your surfboard has FCS II fin boxes before purchasing.

These fins excel in open-face, down-the-line waves. Their design provides the drive and hold needed for point and reef breaks where you want to draw out your turns.

Performance Glass is stiffer than other materials, which gives you a more responsive feel and increased stability. It is an excellent choice for larger surfers or those who prefer a solid, predictable connection with the wave.

While they are optimized for the volume and rail line of mid-length boards, they can be used on other boards if you are looking for extra drive and hold. However, their template is specifically tuned to handle the characteristics of mid-length shapes, particularly those with deep concaves and moderate-to-extreme rocker.

The XL sizing indicates these fins have a larger surface area, which generates more drive and hold. This makes them ideal for larger surfers or anyone needing extra stability and projection through turns.
