#unchartedrocks – The survey ships of the INFOMAR project – the Marine Institute's Celtic Voyager and the Geological Survey's Keary, Geo and Cosantoir Bradan – have been busy recently, and a lot of previously uncharted rocks have now been surveyed and notified to the UK Hydrographic Office for inclusion on the charts writes Norman Kean of the Irish Cruising Club. A couple of known rocks have also had their depths revised shallower, and would now be recognised as a significant hazard to small craft.

The most important new discoveries are these (Admiralty Notices to Mariners numbers in brackets):

• Rock with 2m, 2 cables off Rush Bay (1381/2014)
• Rock with 1.2m, 2 cables east of Loughshinny pier (1381/2014)
• Rock charted at 3.4m, north-east of the Fastnet, re-surveyed at 2.2m (0496/2014)
• Rock with 0.8m, halfway between Colleen Og Rock and the shore, at Dingle
• Numerous rocks around Inishskinny and south of Inishbofin (2672/2014)
• Rock with 1.5m, 2 cables south-east of Knife Rock, at Benwee Head in Mayo (3994/2014)
• Ballyhiernan Rock, west of Fanad Head, resurveyed from 3.4m to 1.7m (2620/2014)

The leisure sailing community has also made its contribution. A rock with 0.1m was discovered in Crookhaven Harbour in July by the crew of the yacht Eleanda (3645/2014). Fortunately she didn't hit it, but when they looked over the stern at low water on their anchorage, there it was, lurking a metre down. And very, very solid.

Not every change has been for the shallower – Limeburner Rock, off north Donegal, has had its depth revised from 2m to 3.5m.

It may be true that the rocks don't move, but the ever-increasing accuracy of the charts means that our knowledge of their existence, position and depth is constantly improving. Don't assume that your chartplotter package will pick this up automatically – it's best to check. The relevant Notices to Mariners can be found on www.ukho.gov.uk.

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.
