The Prince of Wales visited the latest addition to the Caithness fishing fleet during a visit to Scrabster harbour.
Charles, known as the Duke of Rothesay in Scotland, carried out the engagement on Tuesday after beginning his annual visit to the nearby Castle of Mey earlier this week.
His first official duty of the day was to meet the crew of the Boy Andrew, a 27.5-metre seine netter costing £2.8 million and built by a Danish company.
Charles, sporting a Charles Edward Stuart kilt, was introduced to the boat's skippers and crew when he arrived at the quayside.
He was then escorted on board before being shown around the deck, engine room and wheelhouse.
The Boy Andrew and its sister vessel the Opportune are the only two white fishing vessels which operate from Caithness.
Skipper Andrew Bremner Senior said: "He was interested in cod, which is now Marine Stewardship Council-credited, meaning it is now safe to eat as stocks have made a remarkable recovery, and he was interested to find out why.
"He was also interested in the crew and in particular asked the young members about their views on the future of the fishing industry."
Charles then visited the Captain's Galley in Scrabster where he met owners Jim and Mary Cowie, who established the restaurant in 1999.
He was given a demonstration in the restaurant kitchen, where Mr Cowie and staff prepared a dish using cod, monkfish and saithe.
Tourists from the Pacific Princess cruise ship, which was docked at Scrabster, formed a throng outside the restaurant to get a photo of the royal visitor.
The Duke then went on to visit an art exhibition in Thurso and a micro-brewery in John O'Groats.
