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.

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 fuel. Flight safety comes courtesy of redundant propulsion and flight control systems, with next-generation sensor suites detecting and automatically avoiding traffic at sea.

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 world-class operational experience which will help REGENT ensure that our seagliders will be the most convenient and comfortable form of cross-Channel travel.”

REGENT is working on several different sizes of passenger-carrying seagliders, all of which operate on the same principle. Operating a few meters above the water’s surface, they combine the high speed of an aeroplane with the low operating cost of a ship. It has the potential to serve routes of up to 180 miles with existing battery technology, and routes up to 500 miles with next-generation batteries.

Both Brittany Ferries and REGENT understand that many technological, practical and regulatory milestones lie ahead. However, both companies say that caution should not stand as an impediment to the development of a promising concept that already has a history in military applications and smaller leisure craft operating around the world. Both companies look forward to the promise of cross-channel services, reduced emissions, and seagliders becoming commonplace.

For like electric cars, seagliders automatically become greener as more source electricity is generated from renewable sources. And thanks to the inherent efficiency of travelling above water, speed need not be sacrificed to help lower emissions, slow-steaming being one of the solutions proposed for traditional sea-going vehicles to limit environmental footprint.

Dublin Bay

Dublin Bay on the east coast of Ireland stretches over seven kilometres, from Howth Head on its northern tip to Dalkey Island in the south. It's a place most Dubliners simply take for granted, and one of the capital's least visited places. But there's more going on out there than you'd imagine.

The biggest boating centre is at Dun Laoghaire Harbour on the Bay's south shore that is home to over 1,500 pleasure craft, four waterfront yacht clubs and Ireland's largest marina.

The bay is rather shallow with many sandbanks and rocky outcrops, and was notorious in the past for shipwrecks, especially when the wind was from the east. Until modern times, many ships and their passengers were lost along the treacherous coastline from Howth to Dun Laoghaire, less than a kilometre from shore.

The Bay is a C-shaped inlet of the Irish Sea and is about 10 kilometres wide along its north-south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sandbanks lie, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.

Dublin Bay FAQs

There are approximately ten beaches and bathing spots around Dublin Bay: Dollymount Strand; Forty Foot Bathing Place; Half Moon bathing spot; Merrion Strand; Bull Wall; Sandycove Beach; Sandymount Strand; Seapoint; Shelley Banks; Sutton, Burrow Beach

There are slipways on the north side of Dublin Bay at Clontarf, Sutton and on the southside at Dun Laoghaire Harbour, and in Dalkey at Coliemore and Bulloch Harbours.

Dublin Bay is administered by a number of Government Departments, three local authorities and several statutory agencies. Dublin Port Company is in charge of navigation on the Bay.

Dublin Bay is approximately 70 sq kilometres or 7,000 hectares. The Bay is about 10 kilometres wide along its north-south base, and seven km in length east-west to its peak at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south.

Dun Laoghaire Harbour on the southside of the Bay has an East and West Pier, each one kilometre long; this is one of the largest human-made harbours in the world. There also piers or walls at the entrance to the River Liffey at Dublin city known as the Great North and South Walls. Other harbours on the Bay include Bulloch Harbour and Coliemore Harbours both at Dalkey.

There are two marinas on Dublin Bay. Ireland's largest marina with over 800 berths is on the southern shore at Dun Laoghaire Harbour. The other is at Poolbeg Yacht and Boat Club on the River Liffey close to Dublin City.

Car and passenger Ferries operate from Dublin Port to the UK, Isle of Man and France. A passenger ferry operates from Dun Laoghaire Harbour to Howth as well as providing tourist voyages around the bay.

Dublin Bay has two Islands. Bull Island at Clontarf and Dalkey Island on the southern shore of the Bay.

The River Liffey flows through Dublin city and into the Bay. Its tributaries include the River Dodder, the River Poddle and the River Camac.

Dollymount, Burrow and Seapoint beaches

Approximately 1,500 boats from small dinghies to motorboats to ocean-going yachts. The vast majority, over 1,000, are moored at Dun Laoghaire Harbour which is Ireland's boating capital.

In 1981, UNESCO recognised the importance of Dublin Bay by designating North Bull Island as a Biosphere because of its rare and internationally important habitats and species of wildlife. To support sustainable development, UNESCO’s concept of a Biosphere has evolved to include not just areas of ecological value but also the areas around them and the communities that live and work within these areas. There have since been additional international and national designations, covering much of Dublin Bay, to ensure the protection of its water quality and biodiversity. To fulfil these broader management aims for the ecosystem, the Biosphere was expanded in 2015. The Biosphere now covers Dublin Bay, reflecting its significant environmental, economic, cultural and tourism importance, and extends to over 300km² to include the bay, the shore and nearby residential areas.

On the Southside at Dun Laoghaire, there is the National Yacht Club, Royal St. George Yacht Club, Royal Irish Yacht Club and Dun Laoghaire Motor Yacht Club as well as Dublin Bay Sailing Club. In the city centre, there is Poolbeg Yacht and Boat Club. On the Northside of Dublin, there is Clontarf Yacht and Boat Club and Sutton Dinghy Club. While not on Dublin Bay, Howth Yacht Club is the major north Dublin Sailing centre.
