The Summer vibes Quad Keel 4-Fin Set – FuturCompatible (FG Carbon) is built for surfers who want serious speed, bite and hold, without losing that smooth, flowing keel feel. Designed as a quad keel setup, it blends the drive of a twin keel with extra control and grip from the rear trailers – perfect for fish, hybrid and modern quad surfboards in everyday Aussie conditions.

Featuring a fibreglass + carbon construction, these fins deliver a crisp, responsive flex pattern with plenty of stiffness for power through turns. The carbon reinforcement adds extra snap and drive off the bottom, while the fibreglass base keeps things predictable, stable and locked-in when you’re on rail.

This FuturCompatible base is made to slot cleanly into Future-style fin boxes, giving a rock-solid fit and excellent energy transfer under your back foot. The template and sizing make this an epic upgrade for Summer vibes Fish surfboards and other performance quads like the Seaside where speed, drive and control matter.
