The sea terminology is accurate and unusual (allowing for landsmen's inventions). The placenames in Ireland generally circle around Waterford and the nearby resort of Tramore. Tramore is not the port for Waterford, which has its own docks. But Dunmore is a fishing port at the entrance to Waterford Harbour. I have a relative, by the way, who is descended from a family who owned ships that traded to the West Indies. In McColl's version the protagonist (Arthur Hollander) is apprenticed to a butcher in Wicklow, further up the east coast, and contains the wonderful line 'I wore the bloody apron there for three long years and more'.
