The MV Royal Iris is a twin screw, diesel-electric, former Mersey Ferry. The vessel was built by William Denny & Brothers of Dumbarton (Yard No. 1448) and launched in December 1950, costing £256,000.

Her engines were produced by Ruston & Hornsby Metropolitan-Vickers. Propulsion: 4 oil 4SA, each six cylinders driving four generators, each 300 kW/300v DC-connected to two electric motors, each 730shp and 2 shafts. Her maximum speed is 12 knots. Her weight is 1,234 gross tonnes. She is 159 feet long and 48 feet wide, with a draught of 9 feet. At least during the first decade of her life, the ship's diesel-electric propulsion made her more economical to run than the other vessels in the fleet.

Famous quotes containing the word royal:

    Are you there, Africa with the bulging chest and oblong thigh? Sulking Africa, wrought of iron, in the fire, Africa of the millions of royal slaves, deported Africa, drifting continent, are you there? Slowly you vanish, you withdraw into the past, into the tales of castaways, colonial museums, the works of scholars.
    Jean Genet (1910–1986)
