The Dee Why class ferries, Dee Why and Curl Curl, (named after popular Northern Beaches in Sydney, were, from 1928 until 1938, the largest and fastest ferries on Sydney Harbour, being used on the Circular Quay to Manly route.
The Dee Why and Curl Curl, were built for the Port Jackson & Manly Steamship Company (PJ & MS Co) by Napier and Miller at Old Kilpatrick, Glasgow, Scotland. They were of a design by naval architect E.H. Mitchell. Mitchell was given the basic specifications by W.L. Dendy, then the General Manager of the PJ & MS Co.
In keeping with all other Manly ferries of the time, they were of steel construction, but with a wooden superstructure, and were double-ended. Each was 220 feet long, 35 feet 11 inches broad, and drawing 12 feet six inches of water when fully laden. Each displaced 799.5 tons of water. They were the second-last steam powered ferries built for the PJ & MS Co, possessing triple-expansion steam engines manufactured by David and William Henderson and Co, of Glasgow, producing 3,200 horsepower, enough to propel the Curl Curl through the water at over 18 knots.
For an unknown reason, the Dee Why was never as fast as her sister ship. Both ships exceeded 17.5 knots on their trials. Steam for the engines was provided by four single-ended cylindrical Scotch boilers, placed in pairs back to back in two stokeholds, and fitted for burning either oil or coal. This arrangement necessitated the use of two funnels, which, because of the arrangement of the boilers, had to be placed slightly forward of amidships, resulting in a strangely asymmetrical appearance. Each boiler was 11 feet six inches long, and 12 feet wide. The propellers were of solid bronze with four blades, being nine feet three inches in diameter. Each ship had a passenger capacity of 1,500.
