Pump Foil

Pump Foil is a discipline where you ride a hydrofoil board on flat water without any external power. You do not rely on wind, waves, or a motor. The rider generates all the speed and lift through physical movement alone.

The session typically begins with a "dock start." The rider runs along a dock, a boat, or a rock and jumps onto the board. The goal is to land smoothly and immediately start the pumping motion to prevent the board from sinking.

To keep moving, you must "pump" the board using your legs. This rhythmic up-and-down motion drives the foil underwater, creating forward thrust. It allows you to glide across the water for as long as your energy lasts.

The equipment is designed for maximum efficiency. The boards are very small, short, and lightweight. The foil wings are usually large with a high aspect ratio (long and thin), which helps them glide further with less effort.

This is an excellent workout and a technical challenge. It can be practiced anywhere there is water, such as lakes, rivers, or harbors. Learning to pump effectively improves your skills for all other foil sports, especially Prone Foil.
