FCS II Skindog Longboard Fin

The FCS II Skindog Single Fin, developed in collaboration with UK longboard champion Ben Skinner, offers a powerful, stable and high-speed setup for versatile longboarding.

Overview

The Skindog Single Fin is designed to deliver a powerful yet fluid feel, perfect for harnessing speed and control in bigger surf. Paired with the Skindog Side Bytes, it creates a 2 + 1 setup that enhances drive, stability and manoeuvrability. The side bytes add speed and control, allowing surfers to handle critical sections and maintain stability through sweeping turns.

The fin features Performance Core (PC) construction with AirCore technology: a pressed polyurethane foam core that mimics the geometric foil of the fin, reducing the amount of fibreglass needed in the resin transfer moulding (RTM) process. The result is a significantly lighter fin with precise flex characteristics, enhancing responsiveness and control while maintaining durability across a variety of wave conditions.

Ben Skinner's Signature Longboard Template

Complementing his highly technical Thunderbolt range, the template offers a balance of drive and hold, with enough pivot to execute tight turns and more radical manoeuvres. Recommended for single fins and mid-lengths. Combine with Skindog Side Bytes for added performance and control in powerful surf.
