On Thursday 19 June 1884, Mona’s Isle suffered a mechanical failure; one of her cylinders and a piston rod being damaged.

[3] Departing Liverpool at 13:05hrs with approximately 250 passengers embarked,[3] Mona’s Isle cleared the Victoria Channel and set a course bound for Douglas.

[3] She passed the Tynwald, which was engaged in accompanying yachts racing in the Mersey, at 14:30hrs[3] which reported her to be making good speed.

Passage was slow, and it was not until 05:00hrs the following morning that the two vessels arrived in Douglas; where many people had stayed on the Victoria Pier all night, anxious to receive news.

On passage from Douglas to Liverpool damage was done to one of her paddle wheels and they were later strengthened, with a set of new composite floats fitted in 1886.

[citation needed] On 8 March 1887, the schooner Constance collided with Mona's Isle at Liverpool and sank without loss of life.

[4] In September 1892 she went aground at Scarlett Point, Castletown, while rounding the south of the Island, homeward bound from Dublin.

She was fast aground for two days, and was re-floated after assistance from Tynwald, her passengers having previously been landed onto the rocks by way of a rather precarious ladder from her bows.

At about quarter past nine the IOMSP Co. vessel, Tynwald, came steaming round Langness and dropped anchor about half a mile from the shore, in the vicinity of the Mona's Isle.

[citation needed] She was present on the south coast of England briefly in 1902, being on charter for the Fleet Review at Spithead for the coronation of King Edward VII.

Perhaps her most noteworthy mission was to the wreck of a Dutch steamer that had been torpedoed and sunk beyond the Cork lightship off the southern Irish coast.

Gold valued at £86,000 was recovered, after which the paddle steamer made fast getaway from an area where German submarines were particularly menacing.

The Mona's Isle had a number of varied missions; she patrolled the west coast of Ireland, she assisted in rescue work from a sinking warship and she searched for survivors from two British submarines that had been lost.
