He is more used to dodging waves in the North Sea while hunting for the catch of the day, as immortalised in the TV series Trawlermen.

But today, Scottish fisherman Jimmy Buchan guided his trawler boat and its small four-person crew, including two volunteers who bid for the pleasure to join his journey, up the River Thames and into St Katharine Docks.

There the Amity II will remain, in the shadow of Tower Bridge, until Sunday when Jimmy will cast off again for the return journey up the east coast of the British Isles to get back to Peterhead.

He said: “It’s a very exciting time for me.

“It’s quite unusual to get a Scottish trawler so far up the Thames so we’ve had a lot of people milling about to have a look.”

His 900-mile journey is intended to raise funds for the Fishermen’s Mission, a charity which provides emergency and welfare support to fishermen and their families in the UK.

He said: “I’ve achieved raising its profile and I’m proud to be able to that.”

Jimmy and his crew are hoping to promote the best of Scottish seafood and he will be cooking up langoustines on board on Friday.

His memoir, Trawlerman, about life doing one of Britain’s most dangerous jobs is also available from tomorrow.
