The Performer Twin + Stabiliser is one of the most versatile fin setups in the range. Designed to bridge the gap between a twin fin and a thruster, this configuration delivers the freedom and speed of a twin with the added control and predictability of a thruster.
Think of the Performer Twin as 2/3 Twin and 1/3 Thruster. The smaller side fins generate speed and looseness, while the oversized stabiliser provides the control needed to hold your line when pushing harder through turns.
Adaptable across modern twin, hybrid, and performance shapes, this setup offers a unique balance of flow, release, and stability.
The Performer Twin combines the playful speed and freedom of a twin fin with the stability surfers expect from a thruster setup.
The smaller Performer-style side fins feature a neutral sweep and streamlined outline that encourages quick acceleration and smooth rail-to-rail transitions. Meanwhile, the larger Carver-style stabiliser increases the overall surface area of the set, delivering added control when driving through turns or navigating steeper sections.
The result is a setup that feels fast and loose when you want it, yet predictable and controlled when you need it.
