Duotone Grip 4 SLS 2025

A windsurf board in FULL CUSTOM construction deserves a little extra care to last for many seasons. Rinse the board with fresh water after every saltwater session, especially the fins, fin boxes, mast track, and screws, where salt crystals quickly build up and can cause metal parts to seize. Wipe the board with a soft cloth and let it dry completely before putting it away.

Avoid leaving the board in direct sunlight for long periods, as UV rays gradually degrade the laminate, footpads, and graphics. Store it in a cool, dry, flat place, preferably in a padded board bag, and avoid placing heavy objects on top of it. Always use the correct tools when installing or adjusting fins, and don't overtighten them. Regularly check the fins, screws, and PLAN mode for damage, and repair minor chips promptly to prevent water from getting into the core. During transport, secure the board firmly to the roof rack and use pads to prevent the deck from getting scratched.

What is the Duotone Grip 4 SLS 2025?

It’s a dedicated quad-fin waveboard from Duotone’s World Cup series, built using FULL CUSTOM SLS technology and developed in collaboration with PWA riders such as Victor Fernandez. It’s made for wave riders who want maximum grip and drive in their turns.

What sizes is the board available in?

The Duotone Grip 4 SLS 2025 is available in seven sizes from 69 to 107 liters (69, 76, 81, 87, 93, 99 and 107), so there’s a model to suit a wide range of weights and skill levels.

What do SLS and FULL CUSTOM technology mean?

SLS stands for Strong-Light-Superior, and the 2025 model is built using full custom construction, making the board about 200 g lighter and significantly stronger than boards with standard semi-construction.

What’s the difference between the Grip 4 and Grip 3?

The Grip 4 has a quad-fin setup for maximum drive and grip through rail-to-rail turns, even in big waves. The Grip 3 has a thruster setup for slightly better acceleration and earlier tail release for tighter, sharper turns - even in less-than-perfect waves.

Is the board easy to set up?

Yes, it’s specifically built for plug & play: The side fins are set in fixed mini boxes with no adjustments, and all fin tuning is done using only the center fin(s), so you’ll be on the water in no time.

Why does the board have a mini mast track?

The mini mast track saves weight in the nose and also reduces the risk of placing your mast foot incorrectly, while still giving you enough adjustment range for all sail styles and sizes.

How do I choose the right size?

Choose the volume based on your body weight, skill level and the wave conditions you typically sail in - the lower the volume, the more demanding the board. If you’re unsure, it’s a good idea to contact us so we can find the right size for you.

How do I best care for the board?

Rinse it with fresh water after use in salt water, let it dry before putting it away, and store it in a cool, shaded place in a board bag. Avoid prolonged direct sunlight, and check the fins and screws regularly.
