Description

Program

A retro keel inspired by Mini Simmons designs, built to generate maximum speed and glide in small waves.

Presentation

The Brown is the most retro and specific fin in the keel range. Directly inspired by fins used on Mini Simmons boards, it has been designed for very wide, low rocker boards with a clear program: early entry, immediate speed generation and effortless planing across the water surface.

Its design is based on a very specific combination: a wide base, large surface area and relatively reduced depth. This geometry creates highly efficient linear drive from the very first moments of glide. Unlike other fins that “bite” into the wave, the Brown delivers a planing sensation, almost as if the board is skimming over the surface.

The behavior is very smooth and very stable along the line, but with limited pivot. The Brown is not designed for tight turns or vertical surfing. It excels in a horizontal style of surfing, focused on glide, open lines and smooth transitions.

Template

Mini Simmons inspired template, wide and rounded. The rake is moderate to strong, favoring stability along the line and long trajectories. It limits pivot and reinforces directional behavior.

Base

The base is very wide, generating immediate drive and strong acceleration. It is essential for producing speed on very wide boards.

Depth

The depth is relatively low, which reduces drag and promotes planing. This frees the board and enhances the feeling of speed.

Surface area

The surface is significant and well distributed, providing stability and lift. It helps maintain speed even in soft sections.

Setup

The twin keel setup is a configuration oriented toward natural speed, projection and stability. Thanks to their very long base and large surface area, keels generate continuous drive that allows the board to accelerate effortlessly and maintain speed along the line.

The feeling is smooth and grounded: the board holds its line, glides naturally and favors long drawn out turns rather than quick direction changes. Surfing is built through continuity, with a consistent line that supports every turn.

This setup is ideal for drawing lines, maintaining speed and using the full length of the wave, with a style focused on flow, glide and wide open turns.

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

For whom?

The Brown is aimed at surfers riding wide boards such as Mini Simmons shapes. It suits an intermediate level. It is ideal for those looking to generate speed in small waves. It promotes a very fluid surfing style, based on glide and open lines. It is less suited to radical surfing. This is a fin for playful and accessible surfing in soft conditions.

What for?

It is ideal for Mini Simmons, very wide fish or voluminous retro boards used in small conditions. Speed comes early and is easily maintained, even in weak or unstructured waves. In this type of waves, it allows you to connect sections effortlessly, generate speed without pumping and surf with a very free and playful style. Perfect for a fun and fluid surfing experience. A very specific and highly effective fin.

What size?

The choice of keel size depends on several factors that work together:

the surfer’s weight
the tail width
the overall volume of the board
the type of waves surfed

A heavier or more powerful surfer will benefit from a larger surface area to maintain control and projection. Conversely, a lighter surfer can slightly reduce the surface area to gain manoeuvrability and freedom under the back foot.

The tail width is also a key factor. Fish boards often have wide tails that generate a lot of lift and natural speed. To stabilise this tail and fully harness that speed, larger keels generally work better. On a narrower fish or hybrid board, a slightly smaller keel will help maintain manoeuvrability.

The overall volume of the board also influences the choice. A voluminous or wide board will require more surface area to remain stable at speed. A more compact or lower-volume board can work with slightly smaller fins.

Finally, surf conditions also guide sizing. In small or weak waves, a larger surface area helps maintain speed and projection. In faster or more hollow waves, a slightly smaller keel can improve manoeuvrability and control through transitions.

In practice, it is about finding the balance between drive, stability and manoeuvrability, depending on the board and the desired surfing style. A large keel favours long lines and natural speed, while a slightly more compact keel delivers a looser and more responsive board.

Equipments

The set consists of two side fins (right and left).

It comes with a fin key for installation.
