Duotone Cosmic (4) SLS (SB, incl. fin) 2027

Duotone Cosmic (4) SLS is a high-performance wave board from Duotone for advanced and expert windsurfers seeking maximum control in powerful ground swell. It is designed for side and side-off winds as well as offshore ground swell at renowned wave spots such as Maui, Cape Town, Brittany, and Cabo Verde. The board is built to hold its line and deliver sharp turns where other boards lose their grip.

The construction is FULL CUSTOM SLS with S_GLASS+ reinforcement, providing a lightweight and stiff build with direct power transfer. The shape system is based on SYNCED CURVES CONCEPT, developed with AI_BOARD_3D software, where the rocker, outline, and rail curve are synchronized for optimal performance. The 2027 update features a refined tail outline, an improved tuck line, and extra nose rocker for cleaner white-water crossings.

• 3-Stage Rocker: Flat midsection for a stable stance, nose rocker for front-foot-initiated bottom turns, and a kickstarter tail kick for sharp top turns.
• Slender outline: A narrower nose and tail than the GRIP model provide more control at high speed and in larger waves.
• V double concave: Transition from V in the front to flat double concave under the feet and mono concave towards the tail for stability.
• Full Custom SLS: A CNC-milled core and custom laminate ensure consistent weight and flex on every board.
• Slot Box fins: Includes fins, so the board is ready to use straight out of the bag.
• For advanced and expert riders: Designed for riders who want to get the most out of their performance in demanding waves.
