Wave Sailing • 3Di Construction • Ultra-Low Swing Weight • Responsive Power
An exceptionally light, dedicated wave sail built for precise turns, fast transitions, aerial maneuvers, and confident control in demanding conditions.
The North Wave 3Di Windsurf Sail GEN1 introduced North’s molded sail technology to performance wave windsurfing. Its one-piece 3Di Dyneema Aramid construction creates an unusually light sail with low swing weight, stable power, and a direct connection between rider input and sail response. It delivers useful drive through lulls, stays controlled when the wind builds, and becomes light and neutral when repositioned through bottom turns, cutbacks, jumps, and transitions.
With published weights starting at only 1.70 kg, the Wave GEN1 feels remarkably light in the hands. Reduced swing weight makes it easier to redirect the sail rapidly during turns, jumps, loops, and aerial maneuvers.
The sail develops a useful, stable profile when sheeted in, providing drive through bottom turns and enough low-end support to accelerate onto a plane or maintain flow through softer sections.
When depowered and repositioned, the sail’s light structure allows it to transition quickly from driving to neutral. This helps riders stay over the board and focus on rail pressure, positioning, and the wave.
The load-oriented fiber structure helps stabilize the sail’s profile despite the reduced batten count. Power remains smooth through lulls and controlled through gusts, making the sail usable across changing wave conditions.
North’s three-dimensional molding process creates the sail body as one continuous structure instead of assembling it from conventional broad panels. This allows precise control over shape, fiber orientation, and material thickness.
Load-oriented Dyneema Aramid fibers produce a light, flexible, and responsive structure. The material layout helps translate wind pressure into forward drive while supporting reliable profile control.
Sizes 3.3–4.7 use three battens for maximum lightness and maneuverability. Sizes 5.3 and 5.8 use four battens to add the stability needed for their larger, more powerful profiles.
Additional fibers are positioned in high-load and impact-prone areas without adding heavy reinforcement across the entire sail. This supports durability while maintaining the sail’s light, lively character.
Batten pockets are incorporated into the molded sail structure for a clean finish and efficient load transfer. This reduces unnecessary construction weight while supporting profile stability.
The clear window provides essential visibility on the wave, helping riders monitor approaching sections, water movement, and other sailors while setting up turns and transitions.
A lightweight composite sleeve complements the molded sail body and helps maintain a direct, responsive connection between the mast, sail profile, and rider input.
The Rock-It Batten Tensioner, EZ Clew, and EZ Downhaul Wave simplify beach setup and adjustment, helping riders achieve consistent trim without unnecessary rigging complexity.
Choose your sail size based on rider weight, board size, wind strength, wave power, and whether you prefer more drive or a smaller, more neutral handling feel.
