The lifeboat, under the command of coxswain Nick Keogh with a volunteer crew, proceeded north to the fisherman’s last known position.
Weather conditions in the area at the time were described as moderate seas with a south-easterly Force 4 wind.
Twelve minutes after launching, the lifeboat crew located the man in his small boat near Kiloughter beach, in what Keogh described as “choppy” seas.
A quick assessment found he was unable to get back to Wicklow Harbour due to mechanical problems with the outboard engine.
The boat was taken in tow back to the garbour, where the fisherman was landed safely ashore just before midday.
“We were happy to assist him,” Keogh added.
