At 08:30 local time on Thursday 18th July, Guernsey Coastguard received an Emergency Position Indicating Radio Beacon (EPIRB) alert from French Maritime Rescue Coordination Centre Jobourg. The initial position received placed the vessel in distress 2.5 miles North West of Rousse Pier, North West coast of Guernsey.
The crew of the RNLI's St Peter Port All Weather Lifeboat "Spirit of Guernsey" was immediately paged in order investigate and a "Mayday Relay" message was broadcast to all vessels in the area.
At 08:45 local time, Guernsey Coastguard received a revised position indicating that the vessel in distress was less than 400 yards from Rousse Pier.
Further information was received from Falmouth Coastguard indicating that the EPIRB belonged to local fishing vessel "O.C.A".
The RNLB 'Spirit of Guernsey' launched at 0850 however, contact was quickly made with O.C.A. and it was determined that she was safe and well and that the beacon was defective.
The lifeboat was stood down shortly thereafter.
