Incredible James Bond-style electric catamaran that silently 'flies' above the surface of the water
- Quadrofoil uses four C-shaped hydrofoils to lift the craft out of the water
- It has a top speed of 25mph (40km/h) and is quiet and eco-friendly
- The catamaran costs £17,586 ($28,144) and is powered by an electric motor
- Battery gives the craft a range of 62 miles (100km) on a single charge
- The first 100 boats have now been sold and will be delivered early next year
A state-of-the-art James Bond-style craft that lifts above the water could make speedboats a thing of the past.
The Quadrofoil Q2S is a two-seater hydrofoil craft powered by an electric outboard motor.
Because the aluminium alloy vessel sits above the surface of the water, it suffers little resistance and can reach a top speed of 25mph (40km/h).

A state-of-the-art James Bond-style craft that lifts above the water could make speedboats a thing of the past
The shape of the four foils creates lift, to haul the vessel above the surface of the water and travel with minimal water resistance and in turn very little noise.
While the boat has been in development for several years, the first 100 limited-edition boats have now been sold, expected for delivery globally early next year.
The craft costs £17,586 ($28,144) and is powered by an electric motor and will cost less than 80p ($1.30) an hour to run.
The battery gives the craft a range of 62 miles (100km) on a single charge.
A four-seater version of the boat is currently in development.
Marine engineers from Slovenia, who invented the craft, describe it as: 'A thrilling yet quiet and eco-friendly watercraft'.
'Its silent motor and zero emissions enable it to ride on lakes, rivers, seas & eco-zones where most motor boats and PWCs are not allowed,' they say.
According to its creators, the Quadrofoil is easy to operate and the steering wheel has an integrated touch screen display to show a user how much battery power the boat has left, as well as its range and speed.
The wheel will act as a detachable key, so that no one else can start the engine when it is removed.
The boat has an integrated steering system, which is designed to keep the craft stable, prevents drifting and makes the craft responsive.

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 for 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.
While the boat has been in development for several years, the first 100 limited-edition boats have now been sold, expected for delivery early next year
It is made to stay horizontal at all times because of the foil design, which places the centre of gravity eight metres (26 ft) above the vessel.
The lightweight hull is built from composite materials and weighs just 100kg (220lbs).
Despite claiming the Quadrofoil is unsinkable and super stable, the craft will come with two life jackets, a paddle and safety whistle.
