Description
One of three sketches showing aspects of the Boom Gate at Fremantle. This is the first of its kind in Australia and is designed as protection against torpedo attacks. Electrically operated winches open and close the gate - a steel net supported by metal barrels. When open the boom forms a large V against North Mole. When closed, cable is secured to a chain mooring, the strain taken off the winches, Fremantle, Western Australia.
