Wallaby (ferry)
This would become the standard model for almost all Sydney ferries until the late 20th century, a fleet that would become for a time the biggest in the world.Designed by civil engineer and naval architect, Norman Selfe, Wallaby was the world's second double-ended screw ferry.Double-ended ferries did not need to turn around at the ports, making maneuvering easier and the transfer of cargo and passengers much faster.Wallaby was not an immediate success, and the North Shore Steam Ferry Company continued to build paddle steamers through to 1885.The model became the norm for the fleet which became the largest during the booming early twentieth century before the opening of the Sydney Harbour Bridge.
