The alarm was raised earlier in the afternoon following a report from the crew of a 26ft yacht that they had lost all battery power.
At the time, the occupants were comfortable sailing the yacht towards Baltimore, so the lifeboat was put on standby until they were closer.
However, due to a confused sea in a strong tideway, the yacht was making very little progress towards land and required assistance to get to port.
The inshore lifeboat, helmed by Micheal Cottrell and with crew members Ryan O’Mahony and Colin Rochford on board, left station at 7.20pm and met the yacht three miles west of Cape Clear Island just before 8pm.
Weather conditions at the time were relatively good, with a Force 3 south-westerly wind and a one-metre sea swell.
One of the lifeboat crew went aboard the yacht to assist with rigging a tow and, once that was established at 8.05pm, a course was set for North Harbour in Cape Clear where the vessel was moored safely at 8.55pm.
Speaking following the callout, Cottrell said: “The sailors did the right thing in initially alerting people ashore to their predicament and then seeking the assistance of the lifeboat before darkness when their situation wasn’t improving.”
