Duotone Grip 4 SLS
A World Cup Wave Quad - A full custom windsurfing board to ensure the best possible weight to strength ratio, with a proven and tested shape from the brand with the longest experience in windsurfing board design.
Duotone 2025 Wave and Freestyle boards are made in a full custom technology, making them 200g lighter, yet much stronger than boards made in the usual semi custom construction.
The GRIP SLS Windsurfing boards are constantly evolving designs and constructions to ensure Duotone are continuously at the forefront of development yet with over 40 years of experience. They call them World Cup Wave boards as they are engineered to satisfy the best of the best on all kind of spots around the globe, from jumping-oriented side-on conditions like Pozo to down-the-line groundswell conditions like Hookipa.
During development, the major inputs came from 3-time PWA Wave World Champion Victor Fernandez and our next gen heroes Alexia and Carlos Kiefer and Tobias Bjornaa. Duotone have selected these guys as they all have a very contest oriented riding style. Therefore instead of demanding super specialised and extreme shapes they always aim for:
- Boards that are super balanced and easy to control in all kind of conditions without taking on a life of their own, to score maximum turns and jumps
- Boards that are super versatile to sail and allow front- and back foot riding to get the most out of each wave even when the conditions are changing
- Boards offering a maximum wind range to avoid being forced to switch boards during the heat
Well isn’t that exactly what we all expect from our wave board? And that’s why Victor, Alexia, Carlos and Tobias are Duotone's most important assets in the development process. In fact, all Duotone GRIP SLS production boards are exact replicas of their best boards from the PWA tour.
An important question - Which fin configuration best suits your personal riding style:
- The GRIP 4 with its Quad fin configuration gives you maximum drive and grip for committed rail to rail turns, even in XXL waves
- The GRIP 3 has a slightly better acceleration due an efficient rocker with a lower-drag entry, which is especially helpful in jumping conditions. The Thruster fin configuration allows for earlier tail release for tighter/slashier turns, even in non ideal waves
More on the 2025 GRIP SLS lineup:
- No 5 multi-setup fin-boxes: this just adds unnecessary weight and drag and is always a compromise since every fin configuration requires a different board shape (bottom and rail shape, outline, scoop-rocker line) to exploit its full potential. It also prevents the board from becoming tail-heavy/sticky. Plus finding a good working setup with 5 boxes is just the opposite of plug & play.
- The mini mast track reduces the weight in the critical nose area. It also reduces the risk to misplace your mast base while still providing just the right amount of length adjustment for all riding styles and sail sizes.
- The mini side fin boxes no longer offer any adjustment to prevent misplacing your fins. Now all adjustability for different riding styles and sail sizes is done through the center fin(s) only - simple and lightweight!
- Our exclusive FULL CUSTOM layup based on over 40 years of experience got refined by DUOTONE chief board construction and QR manager Vasin Siritho.
- Even the artwork got weight optimised by switching from heavy PVC to ultralight water-transfer stickers.
