Duotone Crush SLS 2025

Maintenance of your Duotone foilboard

Rinse the board with fresh water after every session in salt water - especially the foil tracks, screws, and box inserts, where salt quickly builds up. Let the board dry in the shade, and avoid leaving it in direct sunlight for long periods, as UV rays can damage both the surface and sealants.

Store the board in a dry, cool place, horizontally or standing on its edge, preferably in a board bag or storage case. Avoid leaving it in a hot car or on a sun-heated car roof. Regularly check the foil tracks and screws for wear or corrosion, and tighten them with the correct tools as needed. Clean stains with mild soapy water - avoid harsh chemicals, solvents, and pressure washing near seams. Check the board for dents or cracks after touchdowns, and repair any damage quickly to keep the core dry.

What is the Duotone Crush SLS designed for?

The Crush SLS is a dedicated prone surf foilboard, built for paddling out into waves and foiling on them. Its flat rocker, raised nose, and wide outline make it ideal for small to medium-sized waves.

What sizes does the Crush SLS come in?

The board comes in two sizes: 4'6" with 30 liters and 4'10" with 40 liters. The smaller version is best for lighter riders, while the larger one offers more volume and paddling power for heavier riders.

Is the Crush SLS also a wing foilboard?

No, the board is developed specifically for prone foiling. Its shape, rocker, and outline are fine-tuned for paddling speed and forgiving touchdowns rather than wing starts.

Can I use my existing foil on the board?

Yes, if your foil uses standard US track mounting. The board is equipped with two US foil tracks that fit most modern foils.

How much does the board weigh, and why is that important?

The SLS construction makes the board extra light, offering easy handling, better maneuverability, and more responsiveness on the water. Its low weight also makes it much easier to transport to and from the beach.

Does the board have footstrap inserts?

No, the Crush SLS comes without footstrap inserts. This deliberate choice keeps the board clean and light, just as it should be for prone foiling.

How big do I need to be to use the 4'6" or 4'10" size?

As a rule of thumb, choose 4'6" (30 L) if you're light and want maximum maneuverability, and 4'10" (40 L) if you're heavier or want easier paddling and earlier wave entry.

How do I best take care of the board?

Rinse it with fresh water after use, let it dry in the shade, and store it somewhere cool and protected - preferably in a board bag. Regularly check the tracks and screws for salt and wear.
