Program

A directional twin fin focused on drive, designed to draw long lines with control and high-speed stability.

Overview

The Echo is the most drive- and projection-oriented fin in the upright twin range. Its more raked template and significant surface area clearly position it as a directional twin, designed to use the length of the wave rather than pivot tightly. Where the Flash is about release and the Lunar about balance, the Echo is about drawing lines.

Its behavior is defined by a strong ability to maintain speed down the line. Once the board is engaged on rail, the fin generates continuous traction that stabilizes the trajectory and allows for long, committed arcs. Surfing becomes smoother and more grounded, with a strong feeling of control at high speed. It performs especially well in waves with long walls, where the goal is to link sections without losing momentum.

It allows for long trajectories, clean lines, and consistent speed even in fast sections. It is the ideal fin for smooth, down-the-line surfing.

Template

Raked twin upright directional template. The pronounced rake promotes projection and long lines. It stabilizes the board in its line and reduces tight pivoting.

Base

The base is wide, generating constant drive and excellent ability to maintain speed through long sections. It reinforces the directional character of the fin.

Depth

The depth is significant, providing a lot of grip and control, especially at high speed or in hollow waves.

Surface area

The surface is generous, increasing stability and hold on the wave face. It allows hard engagement without losing control.

Setup

The twin setup is a configuration that prioritizes speed, glide and freedom. With only two fins, the board generates very little drag, allowing it to accelerate easily and maintain a natural flow down the line.

The feeling is very loose and responsive: the tail remains mobile, rail-to-rail transitions are fast, and surfing is carried with a lot of fluidity. The board turns easily, with a “loose” feel that encourages fast lines and spontaneous maneuvers.

This is an ideal setup for fast, relaxed surfing, using the natural speed of the wave with maximum glide and freedom in line choice.

Technology

Our fins are manufactured from solid fiberglass panels, ensuring outstanding strength and long-term reliability. Precision CNC machining from solid material allows for highly accurate shapes that stay true to the original design, delivering smooth, consistent performance in all conditions. This process also makes it easy to develop different templates and fine-tune performance characteristics to suit specific needs.

The same construction method is used across the entire range, guaranteeing consistent flex patterns and feel between models. This proven manufacturing process provides excellent resistance to heavy loads and exceptional durability.

Highly resistant to torsion, impacts, salt water, and UV exposure, these fins maintain their performance over time while remaining easy to maintain and repair when needed.

Buying guide

Who is it for?

The Echo is aimed at surfers who prioritize long lines and flow. It suits intermediate to advanced riders. It is ideal for those who surf waves with a defined wall and want to draw lines without losing speed. It promotes a fluid and directional style of surfing rather than a radical one. It requires good wave reading. This is a fin for committed but elegant surfing.

What is it for?

The Echo is perfect for directional twins, powerful modern fish and performance twin setups designed for surfing more solid conditions.

It is ideal in point breaks as it favours long lines and offers strong control at high speed. It is a fin oriented toward flow and projection.

When combined with a trailer, it gains even more stability and precision, while still keeping a looser feel than a thruster.

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 drives hard through turns or surfs powerful waves will benefit from larger fins for more stability and projection.

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.
