COSMIC
PERFORMANCE ALL-WAVE
This is the SUP wave hardboard that handles everything, and helps you push your surfing further.


OVERVIEW
Shape & Bottom Design
A round‑point nose provides stability and clean wave entry even at low paddle speed, while the pulled‑in moon tail keeps the board tight, reactive, and precise when the wave demands it.
The bottom contours define the ride: a forward mono‑concave delivers instant speed and keeps the board lively through weaker sections. It transitions into a double‑concave mid‑section for maximum balance and stability. Toward the tail, an opening V releases water efficiently, freeing the tail for quick pivots and that loose, flowing sensation at the end of every turn.
Accelerate. Drive. Release. Repeat.
2+1 Fin System — Most balanced setup
Two multi‑fin boxes paired with a central US box create a classic Thruster setup — the perfect balance of control, drive, and maneuverability from waist‑high waves to solid overhead surf. It’s the universal configuration: precise, predictable, and high‑performing in all wave-conditions.
CUSTOM CNC Construction
The COSMIC is built using DUOTONE’s CUSTOM CNC composite construction — a composite‑wood sandwich layup around a lightweight, CNC‑shaped EPS core with a clean, unfinished aesthetic. Developed and continuously refined through DUOTONE’s long heritage in premium windsurf and foil board manufacturing, this construction delivers an ideal blend of low weight, efficient glide, and exceptional comfort.
Who is the COSMIC for?
The COSMIC is designed for intermediate to advanced SUP surfers who take wave performance seriously.

FLAT SPOT DECK SHAPE
The center of the deck is completely flat. This feels like standing on a jetty providing a stable base for better balance and maximum control.
TECHNOLOGY

CUSTOM CNC TECHNOLOGY
Additional glass reinforcement patches around the critical impact zones ensure structural integrity. A durable outer skin improves the impact resistance. The unfinished look gives it an exclusive, custom-made appearance.

FLAT SPOT DECK SHAPE
The center of the deck is completely flat—right where you stand. Instead of standing on a round log, it feels more like standing on a jetty; this provides a stable base for better balance and maximum control.

GRAB HANDLE
Ensures a secure grip and comfort when carrying your board. The handle features a double-sided design, so you can hold it from either side.

DUO STRUCTURE PADS
The 4 mm thick EVA pads offer the best balance between cushioning/comfort and grip/control. The center section features our signature diamond pattern, which ensures symmetrical grip in all directions. The heat-pressed process protects the EVA against abrasion, ensuring maximum durability. The rear section features a longitudinal cord-groove pattern that provides maximum lateral grip for your back foot, even during the most radical turns. We exclusively select EVA colors that don’t look dirty even after use and won’t fade even after hours in the sun.

DUAL LEASH PLUG
Stay connected to your board at all times thanks to the integrated leash plug. Our custom designed plug features two attachment points to ensure maximum reliability and safety, so you can securely attach your leash and stay firmly connected to your board.

MOON TAIL DESIGN
The Moon Tail behaves very similar to a swallow tail which offers enough counter-pressure for sharp and most pivotal turns. But due to the inverted curve it offers even more grip/hold and control especially in higher waves.

OUTLINE
STABLE YET RADICAL CONCEPT
Our wave boards are approx. 1-2cm wider than most other boards.
The increased width results in a more stable platform. This makes our wave boards as stable as a 5 liter bigger board while drifting/floating and going over white water.

SURFING STYLE RAILS
Harder, pulled down rails towards the tail for maximum grip during the top turns.
Softer beveled rails towards the nose for smooth bottom turns.

BOTTOM SHAPE
Flat single-concave into flat double-concave into opening V (front to back).
In the front the flat single-concave improves the acceleration and take off on the wave.
Just before the front foot it transitions into a flat double-concave to ensure a stable riding position.
Towards the tail the V is gradually increasing which results in a disconnected rocker (flatter rocker line in the center with increased rocker along the rail). The flatter center rocker results in improved planing power while the increased rail rocker improves the water release and turn-ability.

2+1 THRUSTER BOX SYSTEM
This system consists of 2 multi fin boxes (future fin compatible) + 1 US fin box. Three surfboard-style fins of equal size create a true Thruster-fin setup that guarantees an excellent balance between maneuverability and grip on the wave. The asymmetrical side fins provide additional grip even during radical pivot turns.

3-STAGE ROCKER
Unlike the usual continuous rocker curve, our entire shape concept is based on a segmented rocker line. This accounts for the fact that the top- and bottom turn are two entirely different maneuvers. While you initiate the bottom turn more over your front foot (depending on the size of the wave) the top turn is only sailed over the back foot. This change in posture is the biggest challenge, especially when learning to wave ride – which becomes much easier with our 3-STAGE ROCKER.
1) The straight rocker section in-between the feet creates a super stable sailing stance/platform so that you’re in perfect sync with your board going out or on the wave when switching between bottom- and top turn.
2) The nose rocker starts just in front of the front straps which helps to engage the front part of the rail when leaning forward on the bottom turn.
3) KICKSTARTER TAIL: The tail rocker behind the back strap remains very moderate until the last 4-5cm from the tail where it transforms into a progressive tail-kick. This tail-kick generates a perfect water release and in combination with the flat rocker line results in a kickstarter-like acceleration as soon as you push a bit with your back-foot. Plus the tail-kick obviously allows for super tight top turns when snapping back the board with your back-foot.

My board made it ...
But no foot straps, fins, or vent plug?
