Duotone Flow

The Duotone Flow is a perfect blend of tradition and modern performance for Allround SUP and catching your first waves. Inspired by the classic lines of Malibu-style surfboards, this board is not retro just for aesthetics, but for pure functional precision—ideal for those looking for a fluid, unhurried glide with total control.

Its shape has been optimized using Duotone's exclusive 3D design software, guided by artificial intelligence, allowing for millimeter precision in the profile that guarantees efficient paddling in both flat water and beach breaks when surfing.

Thanks to the generous volume distribution in the center section and its natural stability, this board forgives beginners' mistakes and rewards the progression of intermediate riders. It allows everything from walking toward the nose (nose-riding) to drawing wide, smooth turns on the wave face without requiring expert technique.

Duotone Flow Features:

• Custom CNC Construction: Lightweight CNC-milled EPS core with a composite-wood sandwich layup. It offers an unbeatable balance between low weight, stiffness, and riding comfort with an exclusive, custom-made appearance.
• Malibu Longboard-Style Shape: A wide, rounded nose that facilitates early and effortless entry into waves, while also providing superior forward glide on flat water.
• All-Round Performance: Designed to perform across the full spectrum of conditions: flatwater cruising, coastal touring, and small to head-high waves.
• Bottom Design: Starts with a flat single-concave in the front to improve acceleration, transitions into a V double-concave underfoot for added stability, and increases the V towards the tail for cleaner water release and turning capability.
• 2+1 Tri Box Fin System: Consists of two side fin boxes (Future fin compatible) and one center US fin box. This three-fin setup guarantees excellent grip during turns and outstanding straight-line paddle stability.
• Duo Structure Pads: 4 mm thick heat-pressed EVA grip that offers the perfect balance between cushioning and control. It features a symmetrical diamond groove pattern in the center and longitudinal grooves on the rear kick-pad to prevent the foot from slipping during tight pivot turns.
• Squash Tail: An extremely versatile tail design with rounded corners that provides optimum grip similar to a pin-tail, but with additional lift to improve maneuverability at lower speeds.
• Flat Spot Deck: The center of the deck is completely flat right where you stand, providing a very solid and stable base that substantially improves balance compared to traditional curved decks.
• Dual Leash Plug: Custom-designed integrated leash plug with two attachment points to ensure maximum safety and reliability in the water.
