Pat Sweeney, in Liffey Ships & Shipbuilding [Mercier Press, Cork 2010], tells us that in December 1960 Cork Harbour Commissioners got permission to raise a loan of £250,000 to build two diesel-powered tenders to carry passengers to and from transatlantic liners moored in Cobh. The tenders were built by the Liffey Dockyard in Dublin; the MV Blarna was launched in May 1961 and her sister MV Cill Airne in February 1962.
After a varied career, the MV Cill Airne is now back on the Liffey as a floating restaurant. Her website says that she and her sister were the last rivetted ships built in Europe; they were the third-last and second-last ships to be built at the Alexandra Basin, the last being the Shannon Navigation’s Coill-an-Eo.
MV Blarna spent much of her life in Bermuda as a party boat named Canimabut then spent ten years in Canada waiting vainly for restoration or conversion and coming to be regarded as an eyesore. That period is now over: the “Millbank eyesore“, the Canima, sank in December 2012 and “salvage may not be an option“.
