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.
