HMS St Albans is to be guard ship at the Dartmouth Regatta.
The Portsmouth-based frigate – which is being hosted by Britannia Royal Naval College – will arrive at the mouth of the Rover Dart on Thursday night.
On Friday evening, the ship will host a reception and capability demonstration for guests on board.
The next day, around 40 sailors will attend a reception at Bayard’s Cove in the town.
St Albans’ captain, Commander Andrew Block, said he and his ship’s company are delighted to be at the long-standing and popular event.
He said: ‘My ship’s company is proud to represent the Royal Navy as Guardship at the 190th Dartmouth Regatta.
‘The port of Dartmouth and the Royal Navy have a long history together.
‘This relationship is going to grow as Dartmouth becomes the focus for more and more training of the young men and women who will serve at sea, in the air and on land in the naval service, protecting our nation’s interests.’
