Montrose lifeboat launched to secure a rowing boat which had broken its moorings.
The inshore boat launched at 7.05pm on Friday after the alarm was raised by a member of the public who was concerned there may have been someone on board the vessel.
The boat was located between the road and rail bridges on the River South Esk, within Montrose Basin.
Upon arriving at the boat, the crew found there was no one on board and then tied the vessel to shore.
