Mona's Queen was a notable passenger and mail steamer built in 1934 for the Isle of Man Steam Packet Company, representing one of the company's last twin-screw, turbine-driven vessels before World War II. Constructed by Cammell Laird at Birkenhead at a cost of approximately £30,000, she measured 347 feet in length overall (336 feet between perpendiculars), with a beam of 48 feet and a draft of 17 feet. Her registered tonnage was 2,756, and she was designed to carry 2,486 passengers with a crew of 83. The vessel featured five decks: the Boat, Promenade, Shelter, Main, and Lower decks, with elegant design elements including a straight-line hull and elliptical stern, complemented by extensive promenade space and finely appointed public rooms. Powered by twin Parsons steam turbines, Mona's Queen could reach a speed of 22 knots, a performance supported by three oil-fired water tube boilers operating at 230 lbf/in². Her propulsion system included bronze, three-bladed propellers designed in collaboration with the National Physical Laboratory. The ship’s hull was subdivided into ten watertight compartments, with five fitted with sliding doors for enhanced safety. She was equipped with two rudders, one forward and one astern, and a comprehensive array of navigation and communication gear, including Marconi wireless and submarine signal receiving devices. Passenger accommodations were luxurious for the era, with private and convertible cabins, and specialized public rooms decorated in high-quality woods such as sycamore, teak, walnut, and mahogany. The First Class facilities included a ladies’ lounge, smoking room, buffet, and a dining saloon for 90, with arrangements allowing sofas to be converted into sleeping berths. Third Class arrangements featured lounges and dining areas, with large promenade windows for passenger comfort. Mona's Queen served primarily on the Douglas-Liverpool route, also pioneering evening cruises to the Calf of Man. She was a Royal Mail Ship, carrying mail and cargo, including valuables and perishables. Her operational life was cut short during the Dunkirk evacuation in May 1940 when she struck a magnetic sea mine outside Dunkirk harbor and sank within two minutes. The ship’s sinking resulted in the loss of 24 crew members and designated her as a war grave. Her starboard anchor was raised in 2010 as a memorial, symbolizing her service and the sacrifices made during the war.
