2022 Duotone Spirit Surf Foil 75 cm

2022 Duotone Spirit Surf Foil 75 cm

The Spirit SLS is a true inspiration in the SLS (strong light superior) segment, offering an ultra light carbon mast with a glued top plate and a carbon fuselage form fit connection system. A guarantee for speed and control.

Key Features

Duotone Spirit SLS Carve

Lighter and faster

Due to a 30%/500g weight reduction, the Spirit SLS is now lighter and faster!

High Maneuverability and great stability in higher speeds

Even at highest speeds, the Spirit SLS is still very lively and easy to control due to its incredible stability.

Precise feedback

Due to the increased torsional stiffness, the feedback to the pilot is very precise.

Prepreg carbon construction

A very light yet durable carbon construction.

Best load transmission & distribution

Due to an improved mast connection the load transmission and distribution is simply perfect, a must for high top speed and control.

Drag optimized shape and design

Due to improved aquadynamic of the shape, drag could be optimized.

Span Cord Length Area
Front Wing 700 555 MM 158 MM 700 SQCM
Front Wing 950 646 MM 185 MM 950 SQCM
Carbon Back Wing 358 MM 74 MM 216 SQCM


Duotone Spirit SLS GT

The Spirit SLS shows incredible maneuverability and also offers surprising stability at high speeds, making it a fast and fun toy for freeriding and around the racecourse. Its excellent pitch stability gives you the freedom to focus on tactics and how to beat your opponents. Due to the increased torsional stiffness, the feedback of the Spirit SLS is even more direct and predictable than at other foils. This Spirit SLS even offers the possibility to use it additionally for wake surfing and foil winging. The prepreg carbon construction is the latest in foil engineering, making it strong yet super light. A lightweight mast with a geometry focused on stiffness comes on top of this amazing package. The layup of course is also fully committed to lightweight, the weight of the top plate was also reduced in weight. Every single part of the Spirit SLS was constructed to achieve the lightest combination possible, to reach highest speeds with the maximum of control. The Spirit SLS comes as a one-piece mast and plate. The mast connection is built for the best load transmission and force distribution, guaranteeing a fast, stable, drag optimized shape and design. In numbers: a 13% higher bending stiffness was achieved. A fourth front wing insert was added to be able to use even bigger front wings safely. Every single part of the Spirit SLS was constructed to achieve the lightest combination possible, to reach highest speeds with the maximum of control.

Tech Features

Duotone Spirit SLS GT

Mast connection plate with new pocket

The new pocket of the mast connection is a deeper pocket, causing a bigger connection surface between mast and plate and therefor a 40% higher tear resistance



The fuselage back wing connection now has redesigned screw positions compared to last season, avoiding twisting of the back wing a supporting a firm hold without any deformation. Wedges can be used to adjust the back wing to your personal preference.



A completely new aluminium fuselage with pocket for the best and easiest mast connection.


The mast is connected to an aluminium fuselage through a clean pocket connection, improving steering impulse transmission a lot. Special screws are the guarantee for a bomb proof connection and stainless steel helicoil thread inserts make sure it´s a connection made to last.

Fuselage Wing connection (up from size 950)

The new fuselage wing connection is now integrated, causing less drag.

In combination with the smooth trailing edge transition to the fuselage, stunning hydrodynamics are achieved.
