CAIRNS HARBOUR, QLD
Cairns Harbour had three floating docks anchored in the Trinity Inlet and the vicinity of Smith Creek during WWII. The largest floating dock, known as ARD7 (Auxiliary Repair Drydock 7), had been towed from San Francisco and was anchored in Trinity Inlet up stream in the direction of Admiralty Island. It had a tonnage capacity of about 3,000 tons and was able to accommodate two corvettes at the same time.
These three Dry Docks were attached to US Navy's "Escort Base One", Cairns which had been set up for destroyer repair, mine maintenance, patrol craft repair headquarters, and supply after the PT Boat Engine Overhaul Base had left Cairns in October 1943.
There was a smaller dock with a capacity of 100 tons and the third one had a capacity of 400 tons. These smaller docks were towed in sections and then bolted together when they arrived at Cairns. One of these two docks was Mobile Floating Drydock Number 10 (AFD-10).
