GP Hammerhead

Some designs don’t follow trends — they redefine them.

Meet the F4 Hammerhead.

Inspired by the efficiency and precision of its namesake, the Hammerhead brings together extreme aspect ratio, refined hydrodynamics, and controlled maneuverability into a foil that feels fast, efficient, and incredibly composed on the water.

The Hammerhead sits among the highest aspect foils on the market, built with one clear objective — maximum glide with minimum drag.

Once up and flying, the foil carries speed effortlessly. It connects sections naturally, maintains momentum through lulls, and allows you to stay on foil longer with less input.

This isn’t just speed — it’s sustained, efficient glide that keeps building and carrying forward.

Controlled, Not Compromised

High aspect foils are often fast — but they can feel locked in.

The Hammerhead was designed differently.

Through careful refinement of span distribution, curvature, and foil sections, we created a wing that maintains its efficiency while still offering predictable, controlled turning.

It doesn’t feel loose or unstable — it feels precise, composed, and intentional, allowing you to carve clean lines without breaking flow.

Like the hammerhead shark itself — wide, efficient, and highly tuned — the foil delivers both directional stability and refined control.

Engineered for Flow

The Hammerhead isn’t just about numbers — it’s about how the foil moves through the water.

Ultra high aspect ratio for maximum glide and forward projection
Minimal chord profile to reduce drag and improve efficiency
Refined foil sections for smooth lift and low resistance
Balanced curvature for stability at speed and clean turning response

The result is a foil that feels clean through the water, with no wasted movement — just pure, efficient flow.
