The Cosmic (4) D/LAB is Duotone's World Cup wave board for advanced to expert riders chasing ground swell and windy Euro waves from Maui to Cape Town, Brittany to Mauritius. Built as a quad fin wave board in FULL CUSTOM Production technology, it is Made-To-Order with custom-fins included, in sizes 53 to 106 liters.FULL CUSTOM Production is the foundation. Every prototype is made in the factory under identical material conditions. What the team rides is exactly what you get: consistent, reproducible, with full control over weight and layup at every stage.The SYNCED CURVES CONCEPT is the architectural core. Using Duotone's AI_BOARD_3D software, rocker, outline, and rail curvature are synchronized across three zones. Around the mast track, more curvature draws you into the bottom turn. Behind the back strap, the curves tighten again for an explosive top turn. The Cosmic (4) D/LAB transitions between bottom- and top turns without hesitation.The 3-STAGE ROCKER divides this wave board into three zones. A flat mid section gives a stable platform when switching between bottom- and top turn. The nose rocker engages the rail on front-foot drive. The KICKSTARTER TAIL delivers a progressive tail-kick for precise water release, back-foot acceleration, and tight top turns. The STABLE YET RADICAL CONCEPT adds 1–2 cm of width and more outline curvature. With that the Cosmic (4) D/LAB floats through white water like a board 5 liters bigger and carves like one 5 liters smaller.For 2027, every detail is refined. New asymmetric side fins deliver even more drive and grip. A refined layup brings the board weight down by another 100 to 200 g depending on board length. More nose rocker helps you cross even gnarly white water. The refined tail outline sharpens turn-ability and grip. The refined tuck line in the mid-front section improves acceleration and control from entry to exit.Quad setup: ideal for side and side-off conditions and strong current. Not for onshore conditions.Target rider: advanced to expert wave-rider Best for: ground swell to windy Euro waves, side and side-off conditionsKey features:> New asymmetric side fins for even more drive and grip> Refined layup reduces weight by 100–200 g depending on board length> More nose rocker for clean crossings even through gnarly white water> Refined tail outline for sharper turn-ability and grip> Refined tuck line in the mid-front section for improved acceleration and controlQUAD GRIP WITH TOP-TURN SNAP.
