A missing electronic beacon found off the Llyn Peninsula triggered a major search operation.
Two RNLI lifeboats from Porthdinllaen and Trearddur Bay were called out at around 8.45pm last Saturday night, along with the coastguard helicopter from Caernarfon, following reports of an EPIRB being activated 20 miles north of Porthdinllaen.
Both lifeboats and the helicopter carried out extensive searches around the area, but there were no signs of any people or vessels in distress.
After enquiries from Holyhead Coastguard were carried out regarding any overdue vessels, it emerged a fishing boat had lost its EPIRB beacon during heavy rolling seas several days earlier.
The helicopter found a device matching the description and the search operation was stood down.
Dylan Thomas from RNLI Porthdinllaen said: "As always, we were happy to assist in the search...and our thanks go to our colleagues at Treaddur Bay lifeboat station and the coastguard helicopter crew."
