Kirawa was a ferry on Sydney Harbour. She was a near identical sister vessel with Kanangra both of which were launched in 1912 during the early-twentieth pre-Sydney Harbour Bridge boom years of Sydney Ferries Limited.
They were the first of four steel-hulled "K-class" ferries (the majority of the type were timber-hulled).[1] At 45 metres in length and with passenger capacity of almost 1,000, and they were among the largest of the Sydney Ferries Ltd fleet. At launch, the press noted Kirawa was built for the then new Cremorne service,[2] which was then run separately to the Mosman route. She would, however, soon also work the Mosman route with sister Kanangra.
Kirawa was decommissioned in 1953. Sister Kanangra, however, was in passenger service until 1985 and is now part of the Sydney Heritage Fleet and is moored at Rozelle Bay undergoing restoration.
Sydney Ferries Limited generally choose Australian Aboriginal names for the early twentieth "K-class" steamers. "Kirawa" is thought to mean "looking for them".
Kirawa was built for Sydney Ferries Limited during the early twentieth century boom in cross-Harbour travel prior to the 1932 opening of the Sydney Harbour Bridge. At the time, the company ran one of the largest ferry fleets in the world. Both her and sister, Kanangra, were part of broader type of around 25 double-ended timber screw ferries - the Sydney K-class ferries - that the company commissioned between the 1890s and early 1920s to meet the booming demand.
The two ferries followed the Sydney Ferries Limited convention of naming their vessels after Australian Aboriginal words starting with "K". "Kirawa" is thought to me "looking for you".
As with all the K-class and Manly ferries built at the time, she was double ended ferries with wheelhouses, propellers and rudders at both ends.
Unlike the previous K-class ferries that were timber-hulled, Kirawa (and Kanangra) were riveted steel hull vessels, although like the rest of the K-class, their decks and superstructures were timber. Both ferries had five watertight bulkheads. The two were built by Mort's Dock at their Woolwich yard for Sydney Ferries Limited for a cost of £17,873 each.[3] [4]
She had triple expansion coal-fired steam engines, with cylinders of 14-inch, 22 1/2 inch, and 37 inch. diameters respectively and a stroke of 21 inch. Steam was supplied by two navy type boilers, fitted with corrugated furnaces, and having a working pressure of I80 lb. The auxiliaries included an independent centrifugal circulating pump, automatic feed pump, feed heater, and filter, etc. The engines produced 68 hp and pushed her to 13 knots.[3]
Kirawa was launched on 2 July 1912 and christened by Miss Goddard, daughter of W C Goddard, director of Sydney Ferries Limited.[3] Her official trials were held on 29 October 1912 where she averaged 13 knots.[5]
Kirawa, Kanangra and the three similarly sized "Kirrule-type" ferries were built for the booming Cremorne and Mosman routes, with each vessel having an approximate capacity of 1,000 passengers. Demand for ferry services across the harbour were booming in the early 20th century, and in 1911, Sydney Ferries Limited had begun services to the new Cremorne Wharf with new tram connection.
Following the 1932 opening of the Sydney Harbour Bridge, Kirawa was kept in service, while 18, most older ferries, were decommissioned due to the drop in demand. Prior to the bridge opening, Sydney Ferries Limited had transported 40 million passengers a year, which dropped to 15 million after the opening. The drop in demand for the remaining ferry fleet was somewhat mitigated as many could not afford their own transport in the Great Depression of the 1930s and rationing of fuel during World War 2 made the coal required for the steam ferries relatively cheap.[6]
In 1951, as the demand for ferry services dropped further to 9 million following the end of the war, 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. A number of the smaller coal burners were converted to diesel (including Kameruka and Kosciusko). In December 1952, Kirawa was reported as running a showboat excursion.[7]
Kirawa was laid up at the time in need of a new boiler. As there was no longer need for two large ferries, she was sold to be broken up in 1953. Hulked, she was renamed Demolisher and, along with the stripped-down Manly ferry Balgowlah, was used in the demolition and removal of the old Iron Cove Bridge.[6] [8]
Kanangra was converted to diesel power in 1959, and her tall smoke stack was replaced with a smaller exhaust funnel, and the boilers became the fuel tanks. One of the longest serving ferries on Sydney Harbour,[8] Kanangra was withdrawn from service in 1985 and moored adjacent to the Pyrmont Bridge in Darling Harbour. As of 2020, she is currently moored in Rozelle Bay under restoration.
