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:
“a highly respectable gondolier,
Who promised the Royal babe to rear
And teach him the trade of a timoneer
With his own beloved brattling.”
