The SS Mona's Isle (1905) was a notable steam turbine passenger vessel built by William Denny and Brothers in Dumbarton, Scotland. Launched on 11 March 1905 and completed in April of the same year, she featured a steel hull with a length of 311.2 feet (94.9 meters), a beam of 40.1 feet (12.2 meters), and a depth of 15.8 feet (4.8 meters). Her tonnage was 1,671 GRT and 692 NRT. Powered by three steam turbines developing a total of 7,500 indicated horsepower, she achieved a service speed of approximately 22 knots, making her a swift ferry for her era. The vessel was crewed by 70 personnel and certified to carry up to 1,479 passengers. Initially serving as an English Channel ferry for the South Eastern and Chatham Railway (SE&CR), she operated primarily between Folkestone and Boulogne. Notably, she carried King Edward VII from Dover to Calais in 1905. Her early service was marked by a collision in 1908 with another SE&CR ferry, The Queen, which resulted in the death of her bow lookout man and prompted repairs at Dumbarton. She was also the first ferry to carry a motor car across the Channel. During World War I, Onward, as she was then known, transported British troops, including those of the British Expeditionary Force. On 24 September 1918, she caught fire in Folkestone Harbour and was scuttled to prevent the fire from spreading to the pier. Raised later in 1920, she was acquired by the Isle of Man Steam Packet Company (IoMSP), which renamed her Mona's Isle, becoming the fourth vessel of that name in their fleet. She then served mainly summer routes linking Douglas with Dublin and Belfast. Her wartime service resumed during World War II, when she was requisitioned in 1939. Notably, she participated in the Dunkirk evacuation in 1940, becoming the first ship to leave Dover for Dunkirk during Operation Dynamo. During her evacuation missions, she rescued a total of 2,634 troops, enduring enemy shellfire and strafing that caused casualties and damage, including a smashed rudder and near-misses with unexploded shells. Her commander and crew received military honors for their bravery. After the war, Mona's Isle continued to serve as a cross-channel transport until her withdrawal in 1948. She was scrapped in Milford Haven, Wales, on 12 October 1948. Her service history underscores her significance as a passenger vessel, wartime rescue ship, and symbol of maritime resilience during both world conflicts.
