High-speed, sustainable sea glider
Brittany Ferries is exploring the potential for a new high-speed, sustainable, and more efficient form of ferry travel called a sea glider. 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 that could see sea gliders 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.
About the sea glider
Aerodynamic efficiency of hovercraft
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 is expected to fly at speeds of up to 180 mph – six times faster than conventional ferries – with a battery-powered range of 180 miles.
Voyage duration
The voyage from Portsmouth to Cherbourg, for example, could be covered in as little as 40 minutes.
The ground effect
They work by harnessing a concept well-known to pilots – the ground effect. This is the cushion created by high-pressure air trapped between wings and the ground or water while flying at a low altitude. Seagliders are therefore akin to a hovercraft with wings, rather than a skirt.
How does the sea glider work?
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 airflow over wings while riding the air cushion.
Efficient mode of transport
It’s a highly efficient mode of transport, capable of moving significant loads over long distances at high speed. Power will come from batteries rather than fossil fuels. Flight safety comes courtesy of redundant propulsion and flight control systems, with next-generation sensor suites detecting and automatically avoiding traffic at sea.
Priority for energy transition
The energy transition is a priority for forward-looking companies like Brittany Ferries and is key to its recovery post-Covid. Based in Roscoff France, the company has already invested in the delivery of two new LNG (liquefied natural gas) ships for delivery in 2022 and 2023 called Salamanca and Santoña.
Its partnership with REGENT goes one step further. It is a visionary project which offers an exciting glimpse into the future, the kind of vehicle never before seen in Franco-British waters. Brittany Ferries is contributing to development discussions, as the company has a track record in operating fast ferries such as Normandie Express (currently chartered to Condor Ferries).
“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.”
Billy Thalheimer, co-founder, and CEO of REGENT, added “REGENT is excited to partner with Brittany Ferries to bring the future of maritime transportation to market. Brittany Ferries offers a world-class operational experience which will help REGENT ensure that our seagliders will be the most convenient and comfortable form of cross-Channel travel.”
