From 1900, the Balmain New Ferry Company began a period of expansion to keep up and compete with the tram network expanding into what is now referred to as Sydney's Inner West. Older ferries were sold off including several series of "Lady-class" ferries were introduced.
Lady Ferguson was the last of five in the Balmain company's final series of "Lady-class" ferries, the others being
Ladies Chelmsford (1910),
Denman (1912),
Edeline (1913), and
Scott (1914). This series was introduced to replace the single-ended ferries on the Lane Cove River service. They also worked on the run from Balmain to Erskine Street wharf (at site of current
Barangaroo).
Lady Ferguson, and the rest of the Balmain fleet, were bought by
Sydney Ferries Limited as part of its take over of the Balmain company on 1 March 1918. However, after World War 2, the drop in demand for ferry services increased. In 1951, annual patronage dropped to 9 million and the NSW State Government took over Sydney Ferries Limited and its remaining fleet and assets. The
Port Jackson and Manly Steamship Company, which ran the Manly service, was paid to run the services. The services and fleet were quickly rationalised with most of the larger remaining timber K-class steamers being decommissioned. However, the five relatively small and economical "Lady-class" ferries were retained. Throughout the remainder of the 1950s and into the 1960s, they became the back-bone of Sydney Harbour's non-Manly ferry fleet, along with
Karingal and
Karrabee the smallest of the
K-class ferries. Their routes were expanded to all inner-harbour (ie, non-Manly) services including
Taronga Park Zoo,
Milsons Point,
Cremorne and
Hunters Hill. The five sister ferries (except
Lady Scott) were re-engined again in the late 1950s and early 1960s.
Lady Ferguson received a 4-cylinder 300 bhp
Crossley Brothers diesel that pushed her to 10 knots. In the 1960s the Board updated all their ferries' 1930s green and gold livery to a more muted cream and khaki scheme. ==Demise==
