In design, Eagle was not unlike the Belle Steamer fleet ships, with whom she was in competition. Her peace time career was spent on the London-Southend-Margate-Ramsgate-Deal and Dover service.
During the First World War, she saw service as a minesweeper, returning to the GSN Company Thames fleet in 1920.
Eagle's saloon windows were rectangular and of generous size although, as can be seen when compared to Golden Eagle, she had a rather narrow funnel. Originally, she was fitted with a main mast which was later removed. With Captain Knight as her master, she had her name on the bows, in gilt riband and she sported a gold line around her hull. Her paddle boxes were white with the Company's crest in the centre.
She was sold in 1929 to shipbreakers in Holland, where her hull was resold and converted into a landing stage on the River Maas.
