Now hear this, all you sailors or rowers of Greencastle Yawls, Dublin Bay Water Wags, Foyle Punts, International 12s, Shannon One Designs, Castlehaven Ettes, Strangford Lough Clippers, Coastal Hobbler Rowing Skiffs, Dublin Bay Mermaids, Mayfly-Fishing Lakeboats, IDRA 14s, Ballyholme Insects, Classic Ramelton Folkboats and any other boats constructed in what our American cousins would more elegantly describe as the lapstrake method, but we know rather prosaically as clinker-built.

That may sound to the totally uninitiated as something you’d put together from the leftovers in the ashtray of that old heroically-polluting kitchen coke stove upon which the Granny was accustomed to burn the Christmas sprouts long before charred vegetables became – for some inscrutable reason – a favoured item of gourmet dining.

Thus the alternative “clench-built” may be a more accurately descriptive if less-used term to describe this boat-building technique. But either way, the news is that those of you who go afloat in craft built in this way are no longer just going for a race or a sail or a bit of leisurely rowing. On the contrary, you will be engaged in Curating an Item of World Heritage.

This is serious stuff, and Ireland is very much involved in it both through our Dublin Viking boat-building links, and through the Greencastle yawls of the north coast, which were based in the “Drontheim Boats” which were built in Trondheim in Norway – it was the furthest-north Norwegian port with ready access to forest timber - and exported to many northwest Europe ports.

She is named in honour of the renowned Portrush boatbuilder James Kelly, who built many traditional clinker yawls in addition to yachts for the Howth 17 and Dublin Bay 21 classes. Photo: W M Nixon

According to the Press Release from our friends in the Viking Ship Museum of Roskilde in Denmark who led the UNESCO campaign, the official story is that:

“The clinker-built boats of the North – and the traditions associated with them – have now been officially acknowledged by UNESCO as living cultural heritage, which must be safeguarded and preserved for future generations”

So far, so good. But if we go further into the Danish release, that all-embracing term “clinker-built boats of the north” very quickly becomes slightly but significantly re-shaped as “Nordic clinker boats”. It’s true enough up to a point. But the reason we’re so familiar with the Viking Ship Museum at Roskilde is because it was they who achieved the re-creation of one of the largest clinker-built boats ever built, the 100ft Viking ship Sea Stallion, which voyaged from Scandinavia for a year-long visit to Dublin in 2007, and picked up awards for our “Sailors of the Month” while they were at it, but that’s another story.

The fact is the original Sea Stallion was actually built in Dublin around 1042, using timber sourced in Glendalough in County Wicklow, which suggests a very real Irish input. Since then, the clinker-built inheritance has been maintained on our north and northwest coasts, where it goes about as far south as Milk Harbour in County Sligo on the West Coast. Meanwhile, on the East and South Coasts, it continued as the preferred method of construction for smaller fishing craft and – in due course – for leisure dinghies and small yachts.

Back where she belongs……the 30 metre Viking ship Sea Stallion on display in Collins Barracks in Dubin in 2007.

You only have to look at the beautifully-traditional clinker construction of craft like the McDonald of Greencastle-built yawl James Kelly of Portrush, or a Jimmy Furey of Lough Ree-built Shannon One Design, or a West Cork-built Rui Ferreira of Ballydehob Water Wag, to realise that today, some of the best classic clinker-built construction is happening in Ireland.

We may not have invented clinker boat-building, for no one would argue other than that the classic Viking ship is one of mankind’s most remarkable creations. But we can reasonably claim that in awarding global Heritage Recognition to clinker construction, UNESCO is simply catching up with a state of affairs that has existed in Ireland for very many years. Welcome aboard.
