The main shipbuilders were the Kidneys, Risbills, Thompsons and O'Mahoneys. In 1848 Michael O'Mahoney built one of the largest shops - "The Jamestown". Many were employed in associated trades such as sailmaking, blockmaking, shipwrights, ship chandlers.
Edmund Keohan wrote in 1924: ' Dungarvan turned out many vessels which were constructed above where the bridge now spans the river and a century ago ship carpenters were almost always employed in this industry....gradually the trade fell away and the men where employed in repairing vessels. Now the tradesman are gone and it is but seldom that the graving bank (on the causeway, an area for the repair of boats) is occupied with a vessel needing repairs'.
