A concerned member of the public phoned the coastguard to report that there was a small fishing boat about half a mile off Warren Point that appeared to have no navigation lights and wasn't moving. Dart B-825 was tasked to go and check the situation. Once on scene they found that the solo fisherman was not wearing a lifejacket and had no VHF radio, although he did have a mobile phone. He was at anchor fishing. As no further assistance was required, the Lifeboat returned to base.
