Wave Windsurfing

Duotone Cosmic (4) SLS 2027 Windsurf Board

A dedicated ground-swell board for controlled turns in side-shore and side-offshore conditions.

The Cosmic (4) SLS is aimed at advanced and expert wave sailors riding powerful ground swell. It is designed around side-shore, side-offshore and offshore conditions, where control through a committed bottom turn and a responsive top turn matter.

FULL CUSTOM SLS construction uses S_GLASS+ reinforcement. Its three-stage rocker combines a stable area under your feet with a responsive tail, while coordinated rocker, outline and rail curves support controlled wave riding.

For 2027, the tail outline and tuck line are refined for turning and control, with extra nose rocker to help cross white water. This listing covers the Yellow C50 model in 76, 82, 88 and 94 litres, with fins included and Slot Box fittings.

Choose volume around your weight, experience, sail sizes and local conditions. This is a ground-swell-focused design; speak to the TKC team if your regular sessions are in onshore conditions.

Choosing your setup

Tell us your weight, current board volume, sail sizes and usual wave conditions. Volume alone does not determine suitability; your ability to handle the board in lulls and through white water also matters. Ask the TKC team about the right size before ordering.
