A lone fisherman had to be rescued after his mackerel boat capsized off the coast of Peterhead.
He was picked up by another fishing boat, Darcie Girl, and his vessel, Alert, was towed into the harbour by the Aberdeenshire town's RNLI all-weather lifeboat.
The fisherman had to stand on his upturned boat until help arrived.
The emergency call was made at about 2115 BST on Tuesday.
Coastguards said the fisherman had the right safety gear and was wearing a life jacket, and did exactly the right thing by calling for assistance as soon as he got into difficulty.
Peter Duncan, the RNLI's deputy second coxswain for Peterhead's all-weather lifeboat, praised the rescue effort.
He said: 'The Peterhead lifeboat coxswain and crew wish to pass on their thanks and appreciation to the skipper of the Darcie Girl, whose swift and efficient action in responding to the emergency made sure that it did not end up as a major tragedy."
The Alert was towed back to Peterhead and lifted out of the water.
