The "Royal Daffodil II" was constructed by James Lamont and Co. at Greenock and entered service in 1957. She was larger than the Dartmouth pair as she had three decks and was designed for the dual role of ferry and cruise service. The gross tonnage of "Royal Daffodil II" was 609. A gross error was the size of her engines, developing 1,360 bhp a piece she was underpowered and often struggled in strong tides. Aside from the engine order telegraphs, she also had helms in the side boxes meaning that the ship could be steered from them if required. The Roman II was added to her name because of a Thames estuary cruise ship also called Royal Daffodil which existed from 1939 until 1967 (see MV Royal Daffodil (1939)).
