A ferry carrying more than 100 people started drifting off the Scottish coast after it suffered engine trouble on its way to Northern Ireland, the Coastguard said.
The Stena Navigator was travelling from Stranraer to Belfast when both engines suffered partial propulsion failures.
The boat, which had 70 passengers and 47 crew on board, was drifting around four nautical miles west of Corsewall Point lighthouse at the northern end of the Rhinns, Mull of Galloway.
Clyde Coastguard said it received a call from the vessel at 12.50am on Saturday. Two tugboats went to the area to tow the vessel to Belfast, but the Navigator managed to get one engine running and sailed on half power. Clyde Coastguard said the vessel arrived at around 4.30am and everybody on board was safe and well.
