Kaikai (ferry)
Kaikai was a "K-class" ferry on Sydney Harbour. Commissioned in 1907, the timber-hulled steamer was built for Sydney Ferries Limited during the boom in cross-harbour ferry travel prior to the 1932 opening of the Sydney Harbour Bridge. At the time of launch, "Kaikai" was one of Sydney's largest wooden ferries, being the longest and second largest by tonnage. She was a typical example of the "K-class"; a group of double-deck, double-ended, steam-powered screw ferries. "Kaikai" was built for the short but busy cross-harbour route between Circular Quay and Milsons  Point. She survived the 1932 opening of the Sydney Harbour Bridge (17 other Sydney Ferries Limited vessels were sold at the time). She was taken over by the Royal Australian Navy in 1942 and sold for breaking up in 1947. "Kaikai" followed Sydney Ferries Limited's tradition of naming their vessels after Australian Indigenous words starting with "K". "Kaikai" is thought to be an indigenous word for 'food' or 'jewfish'. Background. "Kaikai" 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. She was  typical of a broader type of timber double-ended screw ferry known as the K-class. The company built 25 of these vessels between the 1890s and early 1920s to meet the booming demand. The K-class were all propelled by triple expansion steam engines and were predominantly timber-hulled (four later K-class had steel hulls). Design and construction. "Kaikai's" design was an evolution of Sydney Ferries Limited's K-class design. The hull and deck fittings were designed by J Barber, foreman joiner of Sydney Ferries Limited, under the supervision of, and to a specification by T.  Brown, works manager. She followed "Kareela" (1905) in being the second such ferry to have rounded roofline returns into her wheelhouses, thus fully enclosing the ends of the upper decks. While upper decks had been enclosed since the 1902's "Koree", she and previous K-class steamers ("Kurraba" (1899), "Kirribilli" (1900), "Kummulla" (1903), and "Kulgoa" (1905)) all had open ended upper decks. She was built by David Drake Ltd, Balmain for £13,575. Her keel and keelson were made of ironbark, and at the time of her launch, it was noted to be specially strengthened throughout, with 14 x 14  inch hardwood belting running around the vessel. The floors and frames were of hardwood with the bottom planking also of hardwood throughout, and copper-fastened up to the waterline. She had four wooden bulkheads and one iron bulkhead. The hull was flared out with no overhanging sponsons, with a 4 inch x 1 inch iron sponson band. Her 59 hp triple expansion steam engine and boilers were supplied by Mort's Dock and Engineering to a specification provided by Sydney Ferries Limited works manager, Mr. T Brown. Of direct action, surface condensing type, her engines had cylinders of 13-inch , 21-inch, and 34-inch diameters respectively, with a stroke length of 21 inches. Her two through multi-tubular cylindrical type boilers were both 2.18 m in diameter, 4.6 m in length, and carried a working pressure of 180 1b, with a total heating space of 93 m2. The boilers were fitted with Deightons patent suspension furnace and automatic pumps as well as a fuel heater. She was fitted with a combined steam and hand steering gear from Alley and McClelland's. Electric lights, still a relative recent innovation for ferries, were supplied by Aller and McLellan of Glasgow and  fitted Scott Henderson and Co. When new, she was the longest of the Sydney Ferries Ltd fleet (and second largest by tonnage). A new pontoon was built at Circular Quay to accommodate her. Her 46.3 m length was significantly longer than the next largest ferry, "Kulgoa's", (42.7 m) and her beam was 10.1 m compared to "Kulgoa's" 9.6 m. While her tonnage was smaller than "Kulgoa's" (303 tons vs 338 tons), her rated passenger capacity of 1,250 was similar to "Kulgoa's" 1,255. "Kaikai" was launched on 7 November 1906, and christened by Miss Nina Massic, eldest  daughter of H H Massie and granddaughter of J A Dibbs. She was the eighth Sydney Ferries Limited vessel to use Indigenous names starting with 'K'. "Kookooburra" also under construction at the time of "Kaikai's" launch would be the ninth such vessel. She reached 11.5 knots on her trials on 13 March 1907 which made her the fastest boat in the Sydney Ferries fleet. Service history. "Kaikai" began service on Saturday 23 March 1907 on the Milsons Point run. Following the opening of the Bridge, Sydney Ferries Limited patronage fell from a 1927 peak of 47 million annually to  15 million in 1933. The Milsons Point service, which crossed the harbour at the location of the new bridge, was quickly redundant. 17 vessels from the fleet were retired from service, including K-class ferries of similar age "Koree", "Kummulla", "Kurraba" and "Kirribilli". "Kaikai", however, remained in service. With the Milsons Point and Lavender Bay routes discontinued following the bridge opening, she was used on other routes and for charter and concert events. She was modified with a flying bridge to provide her master with greater visibility in order to follow yacht races. She was taken over by the Navy  in 1942 for use as accommodation ship as part of the War effort. She was purchased by the Navy in 1943 and register closed on 10 March of that year. Following the War, she was sold for breaking up 1947.
