Brittany Ferries to launch all-electric seagliders | News

Brittany Ferries is exploring the potential for a new high-speed, sustainable and more efficient form of ferry travel called a seaglider.

The concept, an all-electric, wing-in-ground effect vehicle (WIG), is under development in the United States through Boston-based start-up Regent (Regional Electric Ground Effect Nautical Transport).

Brittany Ferries has signed a letter of intent which could see seagliders with a 50-150 passenger capacity sailing between the UK and France by 2028.

Regent expects the first commercial passengers to travel on smaller electric craft by 2025.

Seagliders combine the convenience of passenger ferries with the comfort of hydrofoils, the aerodynamic efficiency of hovercraft and the speed of aircraft.

With the potential to connect existing ferry ports, the craft are expected to fly at speeds of up to 180 mph – six times faster than conventional ferries – with a battery-powered range of 180 miles.

The voyage from Portsmouth to Cherbourg, for example, could be covered in as little as 40 minutes.

They work by harnessing a concept well-known to pilots – ground effect.

This is the cushion created by high-pressure air trapped between wings and the ground or water while flying at low altitude.

Seagliders are therefore akin to a hovercraft with wings, rather than a skirt.

Following departure from port, the craft rises on foils insulating passengers from wave discomfort.

In open waters, it takes off, riding the air cushion all the way to its destination.

Wing-mounted propellors provide the thrust to take to the air at low speeds,  while electric motors regulate air flow over wings while riding the air cushion.

“Seaglider is an attractive and exciting concept, and we look forward to working with Regent in the months and years to come,” said Frédéric Pouget, ports and operations director for Brittany Ferries.

“We are particularly pleased to contribute now because it means we can bring real-world challenges and potential applications into the company’s thinking at an early stage.

“We hope this may help bring commercial success in the years that follow. Who knows; this could be the birth of ferries that fly across the Channel.”
