#ferries - Brittany Ferries Cork-Roscoff cruise-ferry Pont-Aven began today its first sailing in 2019 on the seasonal route and will save energy and reduce fuel consumption thanks to the installation of two innovative devices on the ship's propellers.

Wärtsilä‘s EnergoProfin system is a small sub-prop, which is attached to the main propeller helmet, helping improve propulsion in water. Two of these devices were installed during the ship’s dry dock in December 2018. As a consequence fuel consumption and emissions have been cut by around 2% on every crossing.

This project is a small – but significant – step and it comes as part of a range of studies initiated through Brittany Ferries’ Research and Development program. But, as Vincent Coquen, Head of R&D, Energy and Environment for the company, explains, it is not just a question of developing practical and technical solutions for today such as the propellers on Pont-Aven.

“Sustainable development means looking to the future and studying innovative projects and technologies that could be used in either the short or longer term,” he said.

For the past two years, Brittany Ferries has partnered with CEA Tech in France. Several projects are underway, including the development of a long-range broadband link that would use land-based transmitters to obviate the use of satellite-at-sea. A second study focuses on hybrid energy solutions for Cap Finistère, Brittany Ferries cruise-ferry that sails from the UK to Spain. The last is exploring the long-term implementation of fuel cells for powering certain of the ship's on-board systems.

Brittany Ferries is also looking at the potential for wind energy. Flettner rotors, traction wings, or modern sails are at different stages of development, but could significantly reduce ship fuel consumption and therefore emissions.

“Of course, we must be cautious, checking the feasibility of integrating these technologies on board our ships, in terms of safety, reliability and profitability,” added Vincent Coquen. “But I am convinced that they will have a significant role in the equation that ship-owners must solve to achieve the zero emissions ship.”

Ireland's Trading Ketch Ilen

The Ilen is the last of Ireland’s traditional wooden sailing ships.

Designed by Limerick man Conor O’Brien and built in Baltimore in 1926, she was delivered by Munster men to the Falkland Islands where she served valiantly for seventy years, enduring and enjoying the Roaring Forties, the Furious Fifties, and Screaming Sixties.

Returned now to Ireland and given a new breath of life, Ilen may be described as the last of Ireland’s timber-built ocean-going sailing ships, yet at a mere 56ft, it is capable of visiting most of the small harbours of Ireland.

Wooden Sailing Ship Ilen FAQs

The Ilen is the last of Ireland’s traditional wooden sailing ships.

The Ilen was designed by Conor O’Brien, the first Irish man to circumnavigate the world.

Ilen is named for the West Cork River which flows to the sea at Baltimore, her home port.

The Ilen was built by Baltimore Sea Fisheries School, West Cork in 1926. Tom Moynihan was foreman.

Ilen's wood construction is of oak ribs and planks of larch.

As-built initially, she is 56 feet in length overall with a beam of 14 feet and a displacement of 45 tonnes.

Conor O’Brien set sail in August 1926 with two Cadogan cousins from Cape Clear in West Cork, arriving at Port Stanley in January 1927 and handed it over to the new owners.

The Ilen was delivered to the Falkland Islands Company, in exchange for £1,500.

Ilen served for over 70 years as a cargo ship and a ferry in the Falkland Islands, enduring and enjoying the Roaring Forties, the Furious Fifties, and Screaming Sixties. She stayed in service until the early 1990s.

Limerick sailor Gary McMahon and his team located Ilen. MacMahon started looking for her in 1996 and went out to the Falklands and struck a deal with the owner to bring her back to Ireland.

After a lifetime of hard work in the Falklands, Ilen required a ground-up rebuild.

A Russian cargo ship transported her back on a 12,000-mile trip from the Southern Oceans to Dublin. The Ilen was discharged at the Port of Dublin 1997, after an absence from Ireland of 70 years.

It was a collaboration between the Ilen Project in Limerick and Hegarty’s Boatyard in Old Court, near Skibbereen. Much of the heavy lifting, of frames, planking, deadwood & backbone, knees, floors, shelves and stringers, deck beams, and carlins, was done in Hegarty’s. The generally lighter work of preparing sole, bulkheads, deck‐houses fixed furniture, fixtures & fittings, deck fittings, machinery, systems, tanks, spar making and rigging is being done at the Ilen boat building school in Limerick.

Ten years. The boat was much the worse for wear when it returned to West Cork in May 1998, and it remained dormant for ten years before the start of a decade-long restoration.

Ilen now serves as a community floating classroom and cargo vessel – visiting 23 ports in 2019 and making a transatlantic crossing to Greenland as part of a relationship-building project to link youth in Limerick City with youth in Nuuk, west Greenland.

At a mere 56ft, Ilen is capable of visiting most of the small harbours of Ireland.
