The volunteer lifeboat crew were tasked on Friday afternoon (29 May) after reports of the incident off Grey Point.
Arriving at the scene, they found the 13-year-old boy had been retrieved from the water by a motorboat that has seen him in difficulty, and he was safety returned to the beach at Helen’s Bay.
Bangor RNLI emphasises that the boy had no lifejacket on, and that without the help of others “this could easily have turned into a tragedy”.
Now the lifeboat unit is appealing to contact the boy and his family to invite them to visit the lifeboat station when regulations allow, to find out more about what they do.
“We are also interested to find out from him how he felt when he realised things were going wrong, in the hope that this might prevent others getting into difficulty.”
