The Cosmic (3) D/LAB is the thruster in Duotone's wave line — same World Cup shape family as the Cosmic (4), set up with three fins instead of four. It gets the same 2027 updates: more nose rocker, a refined tail outline, a reworked tuck line and another 100 to 200g out of the layup.
Made to order in Full Custom D/LAB with your own colour scheme and a unique serial number.

Why three fins instead of four
A thruster drives. Where a quad grips and turns tight, three fins give you a longer, more drawn-out arc and more speed through the turn — which is what you want when the wave has real size and a proper face to work with. It's the setup for Cape Town, Ireland, the good days in Cornwall, and anywhere the swell arrives organised rather than as wind chop with ambition.
The 2027 changes
Everything the quad gets. A touch more nose rocker for crossing white water, a refined tail outline that improves turn-ability and grip at the same time, and a refined tuck line in the mid-front section for acceleration and control. The layup has been refined again for another 100 to 200g depending on length.
Made to order
Full Custom D/LAB is CNC-shaped and hand-finished, so it is built for you rather than pulled off a shelf. That means your colour scheme and the lightest build Duotone offer — and a lead time to plan around. If you want a board for this winter, order now rather than in January.
💡 Sam's Tip
Honestly? For most people sailing the south coast, the quad Cosmic (4) is the better board — our waves usually want grip and a tight radius, not a long drawn-out arc. The (3) is the one to order if you travel for your waves, or if you're a heavier rider who wants the drive. Come and talk it through before committing; it's a made-to-order board and there's no swapping it afterwards.
