The alarm was raised at 8.35pm when a member of the public contacted the coastguard after passing a small rigid inflatable boat with two men onboard who were fishing near Wicklow Head. Darkness had fallen and the member of the public was concerned for their safety.
The volunteer lifeboat crew conducted a search of the bay, an illumination flare was fired to light up the search area and night vision equipment was also used.
The crew located the small RIB near Wicklow Head using searchlights at 8.48pm but the two men on board said they did not require assistance, and the all-weather lifeboat was stood down shortly before 9pm.
The lifeboat crew on the call-out were coxswain Nick Keogh, mechanic Brendan Copeland and crew members Tom McAulay, Sean Doyle, Dean Mulvihill, Graham Fitzgerald and John Vize.
