Flow
SURF / ALL-AROUND
The wide, harmoniously rounded nose makes paddling in effortless and provides excellent drive on flat water. The generous volume in the center section ensures stability and predictable footing, while the finely tuned tail allows smooth, drawn-out carves and pivot turns — without requiring pro-level skills.
A board that delights beginners, helps intermediate riders progress, and offers experts enough performance to have real fun in steeper waves.
The FLOW stands for smooth, relaxed sessions: gliding with the wave, taking a risk with a nose walk, drawing out long carves, and simply enjoying the feeling of being one with the water.
CUSTOM CNC construction – Premium quality you can feel
The FLOW is manufactured using DUOTONE's high-quality CUSTOM CNC Composite construction. A precision-milled EPS core meets a robust composite wood sandwich and unfinished look — technology derived from DUOTONE's decades of experience in windsurf and foilboard construction.
The result is a balanced combination of low weight, efficient glide, and high comfort.
A shape that grows with you
Whether you are taking your first steps in surfing or refining your classic longboard style — the FLOW will accompany you for years. The natural stability of the Malibu longboard outline gives beginners immediate confidence, while the responsive rails and sophisticated bottom geometry provide experienced paddlers with the precise feedback they need for clean, powerful turns.
This is not a board for just one season — it is a long-term addition to any quiver.
Made for every session
From early mornings on glassy water and small waves to extended coastal tours — the FLOW feels at home everywhere. Its longboard shape glides confidently through chop and open water, while the fin setup provides excellent tracking and high maneuverability.
The ideal board for European conditions: lakes, river tours, Atlantic beach breaks, or Mediterranean point breaks — the FLOW feels at home everywhere.
