A SEARCH for two men in their 30s feared drowned off the Waterford coast resumed at first light today.
A coastguard lifeboat restarted the operation at 4.40am after hopes faded last night of finding the men alive.
A helicopter and a team of naval divers were to join the search later in the morning.
The alarm was raised at about 5.20pm yesterday when a fisherman reported seeing a man calling for help 300m off Helvick Head.
The local man had earlier noticed two men standing in a dinghy, but by the time he got to where he had seen the man in the water, there was no sign of the man or his companion.
It is believed the two men had driven from their home in south Tipperary to Helvick on the Ring peninsula to go fishing.
Superintendent Tom O'Grady of Dungarvan Garda station said there were no reports of anyone failing to return home.
Officers were trying to establish if there was a link with an unattended camper van found near Helvick Head.
In the early hours of this morning, police divers recovered the body of a man from Lough Erne in Co Fermanagh.
It followed reports that a 19-year-old had gone missing while swimming with friends near Castle Archdale Caravan Park.
A man also died in a boating accident on Saturday.
It is thought Martin Mulloy (58) got a foot caught in a rope aboard a small boat he owns at Mulranny pier in west Mayo.
