Description

Program

A lively and technical single fin focused on pivot and glide for precise, committed surfing.

Overview

The Amalgam is a single fin with a strong character, designed for surfers seeking maneuverability, precision, and pure feeling. Its very upright template, inspired by tuna fins, clearly sets it apart from more traditional dolphin or pivot-style fins. It prioritizes freedom, speed, and responsiveness rather than heavy control or locked-in noseriding.

With limited surface area and a relatively narrow base, the Amalgam fully frees up the board. It enables fast rail-to-rail transitions, tight turns, and highly dynamic surfing. The glide is smooth, fast, and direct, with very little drag. In return, it requires good positioning and precise footwork to be fully exploited. This is not a fin that corrects mistakes, but one that rewards precision.

Template

Upright tuna fin-style template. The rake is low, with a very vertical outline. This promotes pivot and fast directional changes, making the fin highly responsive.

Base

The base is narrow, which reduces drag and significantly frees up the board. This increases manoeuvrability but requires more precision in turns.

Depth

The depth must be adapted to the board to maintain control. Proper depth compensates for low surface area and helps maintain grip.

Surface area

The surface is reduced and evenly distributed. This favors speed, glide and a light feel under the back foot.

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 Amalgam is ideal for technical surfers who value precision and want a lively, responsive board capable of carving clean, committed lines.

It suits an advanced level, as it requires good positioning and precise footwork. A perfect fin for surfers who want a reactive and highly maneuverable board.

What is it for?

It is particularly suited to performance-oriented mid-lengths, high-performance eggs, and modern single fin boards, but can also be used as a center fin in a very loose 2+1 setup.

It excels in clean waves with face and defined sections to work. A perfect fin for modern, agile surfing.

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.
