Donaghadee RNLI was requested to launch at 17.50pm last Sunday evening by Belfast Coastguard to go to the aid of a survey vessel which had suffered engine failure.
The 12 metre vessel with two people on board had suffered engine failure north east of Skulmartin, Ballywalter. On arriving on the scene the lifeboat quickly got a tow line onto the stricken vessel which was then taken under tow safely to Bangor marina.
The lifeboat returned to Donaghadee shortly after 8.45pm.
