"Manly" (II) was designed by renowned naval architect, Walter Reeks and was the first double-ended screw ferry on the Manly run. In 1901, Reeks also designed the "Kuring-gai", a steel, double-ended screw steamer that in its appearance, size and capacity, was the first of the familiar Manly ferries of the twentieth century. To meet the expanding demand, the now reincorporated Port Jackson and Manly Steamship Company commissioned six similar double-ended screw steamers: "Binngarra" (1905), "Burra Bra" (1908), "Bellubera" (1910), " Balgowlah" (1912), "Barrenjoey" (1913), and "Baragoola" (1922). In 1928, two new ferries built in Scotland, "Curl Curl" and "Dee Why" were commissioned. They were the largest and fastest ferries on the harbour until 1938 when the Company commissioned South Steyne also built in Scotland.
