HMAS Kuttabul (ship)

Kuttabul had the highest passenger carrying capacity of any ferry on Sydney Harbour and was ordered for the crowded Milsons Point to Circular Quay route.

Prior to the opening of the bridge, peak hour ferries were leaving either side of the harbour at the rate of one fully loaded vessel every six minutes.

[8][5] On the night of 31 May/1 June 1942, three Ko-hyoteki class midget submarines of the Imperial Japanese Navy entered Sydney Harbour with the intention of attacking Allied warships.

According to the official account, only one of the submarines, designated M-24, was able to fire her torpedoes, but both missed their intended target: the heavy cruiser USS Chicago.

[5] The torpedoes, fired around 00:30, continued on to Garden Island: one ran aground harmlessly, but the other hit the breakwater against which Kuttabul and the Dutch submarine K-IX were moored.
