Callout 736

Lifeboats paged at 8.50am. Coastguard had received a call from a concerned member of the public that had seen a submerged speed boat with potential casualties in the water in Castor Bay.
Lifeboats quickly made way to the area and located the vessel which was close to the shore but had taken on water. On initial search no casualties appeared to be in the water.
Crew moored the lifeboat at a nearby fishing quay and searched the shoreline where they found parts of the boat with a few other items including life jackets.
Further information came from coastguard that the occupants of the boat had run aground last night and notified the PSNI but didn’t contact coastguard.
Lifeboats towed the speed boat into the local fishing quay and made way back to base.
(If you are out on the water and something like this happens and you don’t require emergency assistance make sure and notify the Coastguard).
