Touring SUP Flow

flatwaterlongboardsurf

Overview
Classic shape meets modern construction. The FLOW BAMBOO features an outline inspired by Malibu longboards, engineered as a precision instrument. Its wider, rounded nose enables effortless, early entry into waves and delivers excellent forward glide on flat water. The generous volume through the mid‑section keeps the board stable and predictable underfoot, while the refined tail outline supports smooth, extended carves and pivot turns. The board rewards beginners and intermediate paddlers and remains engaging for advanced riders seeking steeper surf. This board is designed for fluid, unhurried riding — trimming along the line, stepping toward the nose, leaning into long carves and enjoying time on the water.

Construction
The FLOW BAMBOO is built using Duotone’s FULL CUSTOM BAMBOO construction — a composite bamboo‑PVC sandwich combined with a lightweight, CNC‑precision‑shaped EPS core. This build is stiff, direct and highly responsive: every paddle stroke and weight shift transfers instantly into the water with no delay. The bamboo sandwich reduces weight while providing durability for frequent use across a wide range of conditions.

Riding Character
Designed to grow with the rider: the natural stability of the Malibu‑inspired longboard outline helps newcomers find balance quickly. Responsive rails and tuned bottom contours give experienced paddlers feedback to draw cleaner lines and surf with more precision. Versatile across conditions: from flatwater paddles to small‑wave surf sessions and coastal explorations. Recommended for lake cruising, river touring, Atlantic beach breaks and Mediterranean point breaks.
