A Coast Guard helicopter and lifeboat last night carried pumping equipment to an Irish fishing vessel which began taking in water.
The trawler, the Paul Stephen, with four people on board, was about 18 miles south-east of Cork Harbour when the alert was raised.
Weather conditions were rough, with force-eight winds and five-metre-high waves.
The chopper from Waterford was scrambled and a lifeboat from Ballycotton was launched.
The 17-metre trawler, out of Greencastle, was escorted to Ballycotton on her own steam as the crew used buckets to bail out water and the life boat volunteers kept a close watch.
The vessel arrived in Ballycotton at about 11pm and a salvage pump was put on board.
