PS Waverley is the last seagoing passenger-carrying paddle steamer in the world. Built in 1946, she sailed from Craigendoran on the Firth of Clyde to Arrochar on Loch Long until 1973. Bought by the Paddle Steamer Preservation Society (PSPS), she has been restored to her 1947 appearance and now operates passenger excursions around the British coast.

PS Waverley is named after Sir Walter Scott’s first novel. Waverley is powered by a three-crank diagonal triple-expansion marine steam engine built by Rankin & Blackmore, Engineers, Eagle Foundry, Greenock, Scotland. It is rated at 2,100 IHP and achieved a trial speed of 18.37 knots (34.02 km/h; 21.14 mph) at 57.8 rpm. Passengers can watch this engine from passageways on either side of the engine room. The main crank is solidly attached to both paddle wheels so they cannot turn independently.

Waverley has had several color schemes in her life. At launch the paddle boxes were painted black, in 1959 they were changed to white, then returned to black but with white edges in 1972, then to all-black in 1977. The two gold stripes along the hull were removed in 1954 but restored during the 2000 rebuild. Today, Waverley has the LNER 1947 livery of red, white, and black funnels, traditional brown-grained (or “scumbled”) superstructure, and black paddle-wheel boxes, decorated with gold lettering on each side.

Waverley makes passenger excursions from various British ports. She regularly sails from Glasgow and other towns on the Firth of Clyde, the Thames, the South Coast of England, and the Bristol Channel. She also undertakes private charters and has provided a period setting for television documentaries and movies, such as Sherlock Holmes: A Game of Shadows (2011).
