Program

The benchmark for classic noseriding, designed to maximize tail hold and stability in the pocket.

Overview

The Royal is a classic hatchet-style fin, directly inspired by historic traditional longboard templates. Its goal is clear: deliver maximum stability on the nose by deeply anchoring the tail in the wave. Thanks to its very straight outline, deep depth, and generous surface area, it acts as a true pivot point, slowing down glide and keeping the board firmly set in the pocket.

The Royal radically transforms longboard behavior. The board becomes more stable, more predictable, and especially much easier to control when moving toward the nose. It allows long, controlled hang fives and hang tens, even in weaker waves, by creating hydrodynamic resistance that keeps the tail engaged in the water. This ability to “hold” the board is essential for extending noserides and maximizing time in the critical section of the wave.

Template

Classic hatchet template. The rake is very low, and this vertical orientation promotes pivot around a fixed point rather than drawn-out arcs. The board turns around the fin and stays locked in the pocket.

Base

The base is relatively short compared to its overall surface, which preserves pivot despite the fin’s volume. It offers a good balance between control and tight turning off the nose.

Depth

The depth is significant, increasing leverage under the board. This strongly reinforces grip and helps keep the tail engaged when the surfer moves forward.

Surface area

The surface is generous and largely concentrated toward the upper part of the fin. This distribution maintains grip even when the base partially exits the water on the trim line, which is crucial for noseriding.

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 Royal is designed for surfers who want to secure their noseride and gain stability. It suits all levels, but especially surfers progressing on a retro longboard. It is ideal for those who want to feel confident on the nose. It promotes a smooth, controlled and composed style of surfing. This fin is perfect for learning or refining a classic style.

It is aimed at surfers who prioritize comfort and stability, who value classic style, flow and noseriding, and who are looking above all for a fin that secures their positioning rather than freeing up the board.

What is it for?

It is particularly suited to bulky retro longboards, shapes with a wide tail, 50/50 rails, as well as boards with a centered or forward wide point.

It excels in small to medium, soft conditions where stability and control matter more than raw speed. Designed to maximize hold, the Royal helps lock the tail into the wave and secure movement toward the nose. Ideal in small conditions where control is essential. A reliable choice for traditional and stylish 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.

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.
