Program

A perfectly balanced all-round fin designed to deliver a smooth blend of speed, control, and maneuverability in all conditions.

Presentation

The Leap is a versatile fin designed to provide a natural balance of speed, control, maneuverability, and flow. It is built for surfers looking for a fin capable of doing everything, without over-specialization, while adapting easily to a wide variety of conditions and boards.

Its neutral template makes it both accessible and high-performing. It allows surfers to link rail-to-rail transitions effortlessly while maintaining enough drive to generate speed through open sections. The board remains stable without ever feeling stiff.

The Leap stands out for its natural and fluid surfing feel. It follows the rider’s movements without restriction, delivering progressive turns and smooth acceleration out of turns. Forgiving yet precise, it works equally well for progression and committed surfing.

It performs well on both shortboards and mid-lengths, across a wide range of conditions. It is the ideal choice for balanced, fluid, and versatile surfing.

Template

Neutral template with moderate rake, combining pivot and projection for a natural and fluid surf feel. It allows linked transitions and progressive arcs while maintaining a perfect balance between maneuverability and control.

Base

Slightly refined base to reduce drag and ease transitions, while maintaining enough width to preserve drive and stability through turns.

Depth

Intermediate depth, offering an ideal balance between hold and freedom. It keeps the board stable while maintaining a smooth and flowing feel in all wave sections.

Surface area

Moderate and well-balanced surface area, promoting a smooth and consistent surfing feel. Transitions remain fluid, with reliable control without excess stiffness, suited for surfers seeking versatility and comfort.

Setup

The thruster setup is a reference for surfers seeking a balance between control, speed, and maneuverability. The center fin provides line hold and stability through turns, while the side fins enhance drive and engagement during direction changes. This setup delivers reliable and versatile performance, suited both to committed maneuvers and more technical sections, across a wide range of conditions.

Technologie

Nos dérives sont fabriquées à partir de plaques de fibre de verre pleine masse, ce qui garantit une excellente solidité et une grande fiabilité. L’usinage dans la masse permet d’obtenir des formes très précises, fidèles au design initial, pour un comportement sain et constant dans toutes les conditions. Cela permet aussi de développer facilement différents templates et d’ajuster les performances selon les besoins.

La même construction est utilisée sur toute la gamme, assurant une cohérence de flex et de sensations entre les modèles. Ce procédé, largement éprouvé, offre une très bonne résistance aux appuis puissants et une excellente durabilité.

Résistantes à la torsion, aux impacts, ainsi qu’à l’eau salée et aux UV, ces dérives conservent leurs performances dans le temps tout en restant simples à entretenir et réparer si besoin.

Buying guide

Who is it for?

The Leap is designed for surfers looking for a versatile and accessible fin. It suits all levels. It is ideal for those who want to progress or keep a simple and efficient setup. It works in all conditions with a well-balanced overall feel. It is predictable and easy to surf. It is a perfect all-round fin for everyday use.

What is it for?

The Leap thruster is an all-round fin that easily adapts to most boards. It works well on both shortboards and modern mid-lengths. Its behavior is balanced, smooth, and accessible, with a good ability to generate speed while remaining maneuverable. It allows effortless transitions and a clean, natural surfing feel. It is an excellent option for versatile and progressive surfing.

What size?

Fin size mainly depends on the following factors:

body weight
surfer’s 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 maneuverable.

Surf style also plays an important role. A surfer who prioritizes quick turns and short transitions may choose slightly smaller fins for more responsiveness. A surfer who drives hard through turns or rides powerful waves will benefit from larger fins for stability and projection.

In general:

Larger = more grip and control
Smaller = more speed and maneuverability

The more voluminous the board, the more fin surface is needed to control it.

Finally, conditions also influence the choice. In small or soft waves, slightly smaller fins help generate more speed.

Whereas 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 maneuverability depending on the surfer, the board, and the waves.

Equipments

The set includes two side fins (right and left) and one center fin.

It comes with a fin key for installation.
