A modern, stable and versatile dolphin fin designed to combine control and maneuverability.

Overview

The Clinch belongs to the dolphin fin family, with a more modern and stable orientation than slimmer or more elongated templates. It is based on an all-round fin concept, but with added surface area and hold, allowing it to maintain control as speed increases.

The balance between base, rake, and surface makes it a very accessible fin, capable of adapting to a wide range of boards and surfing styles. It maintains smooth glide along the trim line while providing enough grip to engage more committed turns. Its behavior remains clean and predictable, making it particularly comfortable in varied conditions, from small beach breaks to more solid waves.

Template

Versatile dolphin template. The rake is moderate, providing a good balance between projection and manoeuvrability. It promotes smooth arcs without locking the board into overly long trajectories.

Base

The base is wide enough to provide control and drive. It maintains good hold in turns while remaining progressive.

Depth

The depth is intermediate to significant, offering good stability and effective hold in fast or powerful sections.

Surface area

The surface is slightly larger than a classic dolphin fin, increasing control and hold without sacrificing glide. It is evenly distributed across the fin.

Setup

The single setup is a configuration based on a single center fin. It prioritizes stability, line reading and smooth trajectories. The fin acts as the main anchor point, guiding the board with precision and continuity.

The feeling is stable and linear: the board holds its line, glides easily and favors long, drawn-out curves rather than quick directional changes. Surfing is built over time, with progressive engagement in each turn.

This is an ideal setup for smooth and controlled surfing, focused on trim, long lines and a natural connection with the wave.

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 Clinch is designed for surfers looking for a versatile solution that can evolve with their surfing and adapt to different wave types without requiring complex adjustments.

It provides easy, efficient surfing and inspires confidence in turns. It suits beginners as well as more advanced surfers and is ideal for modern longboards.

What is it for?

The Clinch is a versatile fin that works both as a single fin and in a 2+1 setup. On a modern longboard, it allows easy switching between noseriding and rail surfing. On a mid-length, it offers an excellent balance between stability and maneuverability. It performs in a wide range of conditions. A reliable all-round option.

What size?

For large retro logs and noseriders, sizes 9” to 11.5” are the most appropriate. The more you prioritize nose riding, hold, and stability, the larger you should go.

As always:

larger = more stability, more hold, more control
smaller = more glide, more freedom, more maneuverability

The right choice depends on the board, the surfer’s weight, wave speed, and surfing style.

Minimum size favors: glide, speed, maneuverability

Maximum size favors: stability, control, noseriding

Example for a 9'2 longboard

9” → more speed and maneuverability
9.5” → more stability
10” → more noseriding

Light surfer → slightly smaller size.

Heavy surfer → slightly larger size.

A simple rule is to choose a fin roughly one inch longer than the board length. This works especially well for classic longboards and noseriders. For more modern or shorter boards, you can slightly reduce size to improve maneuverability and speed.

How to choose between two close sizes?

Within the same fin range, the difference between two sizes (for example 10” and 10.5”) may seem small, but it noticeably affects board behavior.

Example: choosing between 10” and 10.5” on a 9’ longboard

With 10”:

the board feels more lively
turns are easier to initiate
slightly faster glide

With 10.5”:

the board is more stable
the tail stays more anchored in the water
easier noseriding

The 10” suits a more versatile longboard or a surfer who likes to turn. The 10.5” is better suited for a noseriding-focused log.

You can also adjust based on surfer weight, on a 9’6 longboard with the same fin:

a 65 kg surfer may prefer a 10” for more maneuverability
a 85 kg surfer may prefer a 10.5” for more control and hold

Weight directly affects pressure on the fin, and therefore the surface needed for stability.

Adjust based on waves

In slow, soft waves, a slightly larger fin helps slow the board down and stay in the pocket.

In fast or hollow waves, a slightly smaller fin makes transitions easier and increases freedom in turns.

Adjust based on surfing style

noseriding and classic trim → choose the larger size
more turns and freedom → choose the smaller size

When in doubt between two sizes, ask yourself: “Do I want more stability or more maneuverability?”

Larger → stability, noseriding, drawn lines

Smaller → glide, speed, freedom.
