… from the (presumably artificially created) photograph in the Limerick Leader seems to be the Cailín Turána, formerly part of the Aran Islands Fast Ferries fleet at Doolin and seen here out of the water at Cork Dockyard in 2004. The vessel has not been on the Dept of Transport’s List of Certified Passenger Ships since 2007 (and may have come off the list before that: I have not kept copies of the lists earlier than 2007). It could of course have been used in Ireland for purposes other than carrying fare-paying passengers, or outside Ireland for any purpose, after 2004.
And it may be that the vessel shown in the photo is not that which is to be used in Limerick.
