Summer vibes Power Thruster 3-Fin Set Medium FCiiCompatible

The Summer vibes Power Thruster 3-Fin Set – Medium (FCiiCompatible) is built for surfers chasing fast, powerful, high-drive turns in everyday Aussie conditions. With a performance template that balances speed, control and release, this fin set is ideal for surfers who like to push hard off the bottom and hit the lip with confidence.

These fins sit at 4.5 inches in height and use premium honeycomb fibreglass construction, giving them a lightweight yet responsive feel that boosts acceleration, control and overall drive. With a medium size suited to surfers approximately 60-85 kg, this set offers the perfect blend of power and manoeuvrability for a wide range of riders.

The template combines plenty of base for speed with a mid-tip for sharp, snappy direction changes, delivering both power and precision in fun, punchy waves.

This set is FCiiCompatible, slotting straight into any Summer vibes softboard with two-tab fin boxes (all Summer vibes softboards are FCii compatible), as well as any surfboard that uses the FC 2-tab system. It’s a major performance upgrade from standard plastic fins, giving your board a more solid, responsive and high-performance feel under your feet.

The Summer vibes Power Thruster 3-Fin Set – Medium (4.5”) offers a drivey, powerful feel similar to popular high-performance fin templates used for fast, down-the-line surfing and heavy carves. Surfers searching for Mick Fanning MF FCS2 fins, MF performance thruster sets or medium honeycomb fibreglass templates will find a comparable level of projection, hold and responsiveness at a far better price point.

This fin set is ideal for surfers weighing approximately 60-85 kg, though riders up to 90 kg who prefer a looser, more responsive feel may also choose Medium over Large fins. The honeycomb fibreglass design offers stiffness through the base and flex through the tip, helping with fast bottom turns, strong rail engagement and confident top-turn release.

This fin set pairs perfectly with Summer vibes softboards thanks to its FCii compatibility, making it a strong upgrade for foamies, grovellers, performance softboards and everyday PU/epoxy boards. The result is a more responsive, lively and performance-driven ride in waist- to overhead-high surf.
