Quadrofoil: the First all Electric Hydrofoiling Personal Watercraft

AlexTechnology





Quadrofoil is a thrilling, yet quiet and eco-friendy watercraft. It’s silent motor and zero emissions enable it to ride on lakes, rivers, seas & eco-zones where most motor boats and PWC’s are not allowed. No noise, no waves, no emissions.

Quadrofoil is an electric hydrofoiling personal watercraft, which provides the most economically efficient and completely environmentally friendly mode of recreational marine transportation. Due to hydrofoiling and patented steering technology, riding feels like flying onwater and provides an entirely new and thrilling water experience.

WHAT IS A HYDROFOIL? AND WHY DO THEY CREATE LIFT?

The Quadrofoil has four hydrofoils, which are wing-like lifting surfaces that operate in water.
They look like airfoils used by aeroplanes and are mounted on struts below the hull
When speed is gained, they lift the boat’s hull out of the water, decreasing drag and allowing greater speeds.
The foils are shaped to move smoothly through the water causing water flow to be deflected downward, which exerts an upward force on the foil.
This turning of the water causes higher pressure on the bottom and reduced pressure on the top of the foil.
This pressure difference is accompanied by a velocity difference, so the resulting flow about the foil has a higher average velocity on one side than the other.
When used as a lifting element on a hydrofoil boat, this upward force lifts the body of the vessel, decreasing drag and increasing speed.
