The Duotone Ultra Grip Quad SLS 2026 is a windsurfing board built for surfers who want maximum control, stability and an aggressive response in powerful ground-swell waves and European wind conditions. Its shape and construction are based on FULL CUSTOM SLS TECHNOLOGY, meaning precise CNC milling and an optimized material layup, which makes the board strong, light and durable under intensive use. This technology delivers a great weight-to-strength ratio, while still keeping an attractive price point compared to pure D/LAB constructions.
The Ultra Grip stands out with a revolutionary shape concept that offers the stability of a board roughly 5 l bigger while sailing, and balances it with the maneuverability of a board roughly 5 l smaller. This lets the model handle both faster bottom-turn-to-top-turn transitions and hard re-entries and steep wave sections. Additionally, the "Synced Curves Concept" synchronizes the outline, rocker and rail through 3D analysis, improving turn initiation, the smoothness of transitions and overall riding dynamics.
The Quad fin setup in this version provides maximum grip in turns and in strong current, which is especially useful at side-side-off spots and in heavier conditions, where standard setups can lose their hold on the water. This makes it a board designed not only for fast top turns but also for confidently holding your line in intense surf conditions.
The deck construction with a flat area under the feet gives a solid platform for control and confident planing, and the refined outline, rocker and rail - the result of work in our proprietary AI_BOARD_3D software - make the board respond instantly and precisely to changes in trim and body weight.
In summary, the Duotone Ultra Grip Quad SLS 2026 is a high-performance wave board that combines stability and comfort with extreme control and an aggressive, predictable character in demanding ground-swell and windy wave conditions.
