The yacht had a fouled prop and was making slow headway into the wind. Without engine power, they were unable to make their way safely to the Belfast Lough marina.
The inshore lifeboat, led by helmsman Peter Semple, attended – and as they approached the yacht they were informed the fouled prop had freed itself.
The crew offered to escort the yacht to safety to avoid further risk, and this offer was gratefully received.
Once in the marina, the lifeboat ensured all was well and returned to station.
Semple said: "We are delighted to have helped this yacht into the safety of Bangor Marina. In the event, we were not needed to tow the vessel, but the crew were happy to see us.”
