The casualty, a 26-year old man, had quickly got into difficulty and capsized after launching from the Belfast Lough beach in a strong offshore wind gusting up to 30 knots.
This was seen by a member of the public who called 999, and CGOC Belfast Coastguard requested Bangor RNLI to respond.
Arriving on scene within minutes, the crew were delighted to see that the man had stayed with his boat and not tried to make it to shore. They were also happy to report that he was wearing appropriate safety gear: a wetsuit with a buoyancy aid.
After taking the casualty on board and assessing that he was uninjured, they returned him and his boat to the beach where the coastguard were waiting to assist.
Bangor lifeboat helm James Gillespie said: “This man clearly made the wrong decision to attempt to sail in a new boat in such conditions, but by wearing appropriate wet weather gear and staying with his boat he made our rescue much easier.
“The body tires quickly is cold water and he made the right decision to stay with his boat, knowing that his plight had been seen from the shore.”
Bangor RNLI’s deputy launching authority, Bryan Lawther added: “We are delighted to have been to help this man and bring him to safety. He has been advised to further his sailing knowledge with the assistance of a yacht club where rescue services are always on hand for learners.
“After yesterday’s hoax calls, this rescue highlights the importance of our service and our willingness to attend any genuine call.”
