Built by Fairfields at Govan in 1891, Tynwald was the first Isle of Man Steam Packet Company vessel fitted with a triple-expansion engine.

Cojeen,[6] she had a number of close encounters with floating mines but was never hit; the minesweepers worked day and night to keep the approaches to Liverpool open.

[6] On 9 April 1917, a German submarine had penetrated to within a few miles of Liverpool and succeeded in torpedoing the American liner SS City of New York.

The damage to the SS City of New York was in the fore part of the vessel, and, as the bulkhead abaft where she was struck remained intact, the ship was able to float, although the forward compartments were full of water.

Tynwald then sailed again the next morning at 09:00, and upon arrival at Liverpool, having completed three trips and taken in coal, she was told to return to the Landing Stage with all speed.

[6] Enemy submarines were very busy at that time in the Irish Sea, but the Tynwald landed her men safely at Kingstown the following morning.

[6] On another occasion, having arrived at Liverpool Landing Stage, Tynwald was ordered, after discharging mails and passengers, to take coal as speedily as possible.

Upon completion of coaling, she embarked divers and other workmen of the Mersey Docks and Harbour Board along with their equipment, and made passage straight back to the Island.

News had come through that the White Star steamer RMS Celtic had been torpedoed, with the loss of many lives, off the Calf of Man, and was then anchored off Peel, carefully guarded by Destroyers.

On one such occasion, when the Tynwald arrived at the Bar (about 18:45), she had to dodge about with her passengers aboard all that night, and until 19:00hrs the next day, with the constant danger of striking a mine, or of encountering a submarine.

These trips usually took in calls at Morecambe, Douglas and Llandudno On Friday 13 November 1925, the Tynwald fouled the anchor chain of another vessel as she prepared to berth alongside the Prince’s Landing Stage.

[7] Eastern Isles was returned to her owner in 1947 who was faced with an unviable bill for £100,000 (equivalent to £4,942,020 in 2023) in order to put her back into service.
