Power Quad Fins Set - ST Box
Program
An ultra responsive pivot quad fin, designed for tight turns and fast, vertical surfing.
Overview
The Power is the most pivot-oriented fin in the quad range, designed to deliver maximum responsiveness and precision under the back foot. Its highly upright template, combined with a solid base and stiff construction, creates a direct anchor point that allows the surfer to redirect the board instantly. Where some quad setups can feel overly directional, the Power breaks that inertia and makes the board far more lively and reactive.
It allows for quick rail-to-rail transitions, tighter turns, and a more vertical approach through critical sections. Despite its pivot-focused design, it still maintains a solid level of control thanks to its base and well-balanced surface distribution. It performs especially well in fast and technical waves, where the ability to adjust lines quickly is essential.
It is the ideal fin for surfers looking to push a quad setup in a modern and dynamic direction, keeping the natural speed of a quad while gaining maneuverability.
Template
Very upright template with low rake. This promotes tight turns, with strong redirection capability.

Base
The base is relatively wide, allowing it to maintain control and efficiently transfer the surfer’s power through turns.

Depth

Surface area
The surface is concentrated toward the base and quickly tapers into refined tips. This allows a combination of stability in the turn and release on exit.

Setup
The quad setup is a configuration oriented toward speed, grip and projection. The absence of a center fin reduces drag, allowing the board to generate and maintain more speed, especially in fast or hollow sections. The rear fins provide control and hold, while the side fins ensure direction and drive.
This setup delivers fast, fluid and highly grippy surfing, with strong ability to hold the line at high speed. It is particularly suited to powerful waves, long sections, and conditions where speed and control are essential.

Buying guide
Who is it for?
The Power is aimed at intermediate to advanced surfers who like surfing in an active and radical way. It suits riders who prioritize fast manoeuvres, snaps and quick direction changes in the pocket. It requires precision and committed surfing. Ideal for surfers who want a nervous and reactive quad.
What is it for?
The Power is designed for fast shortboards, modern fish or hybrid boards used in fast and technical waves. It is particularly suited to beach breaks and short sections where reactivity is essential. It allows you to energize a quad setup and make it more manoeuvrable without losing speed.
What size?

Fin sizing mainly depends on the following factors:
- rider weight
- surfing style
- board volume
- surf conditions
A heavier or more powerful surfer will need larger fins to maintain enough surface in the water for grip and control.
A lighter surfer can use smaller fins to reduce drag and make the board more manoeuvrable.
Surfing style also plays an important role. A surfer who prioritizes quick turns and short transitions may choose slightly smaller fins for more reactivity. A surfer who pushes hard through turns or surfs powerful waves will benefit from larger fins for more stability and drive.
In general:
- Larger = more grip and control
- Smaller = more speed and manoeuvrability
The more volume a board has, the more fin area is needed to control it.
Finally, conditions also influence the choice. In small or soft waves, slightly smaller fins help generate more speed.
In fast or hollow waves, larger fins provide more grip and security in critical sections.
In summary, the right size is the one that balances speed, control and manoeuvrability, depending on the surfer, the board and the waves being surfed.
Equipments
The quad set consists of two front side fins (right and left) and two rear fins specifically designed for a quad setup.
