HMAS Ararat (ACPB 89)

HMAS "Ararat" (ACPB 89), named for the town of Ararat, Victoria, is an "Armidale"-class patrol boat of the Royal Australian Navy (RAN).
Design and construction.
The "Armidale"-class patrol boats are long, with a beam of , a draught of , and a standard displacement of 270 tons. The semi-displacement vee hull is fabricated from aluminium alloy, and each vessel is built to a combination of Det Norske Veritas standards for high-speed light craft and RAN requirements. The "Armidale"s can travel at a maximum speed of , and are driven by two propeller shafts, each connected to an MTU 16V M70 diesel. The ships have a range of at , allowing them to patrol the waters around the distant territories of Australia, and are designed for standard patrols of 21 days, with a maximum endurance of 42 days.
The main armament of the "Armidale" class is a Rafael Typhoon stabilised gun mount fitted with an M242 Bushmaster autocannon. Two machine guns are also carried. Boarding operations are performed by two , waterjet propelled rigid-hulled inflatable boats (RHIBs). Each RHIB is stored in a dedicated cradle and davit, and is capable of operating independently from the patrol boat as it carries its own communications, navigation, and safety equipment.
Each patrol boat has a standard ship's company of 21 personnel, with a maximum of 29. A 20-berth auxiliary accommodation compartment was included in the design for the transportation of soldiers, illegal fishermen, or unauthorised arrivals; in the latter two cases, the compartment could be secured from the outside. However, a malfunction in the sewerage treatment facilities aboard in August 2006 pumped hydrogen sulphide and carbon monoxide into the compartment, non-fatally poisoning four sailors working inside, after which use of the compartment for accommodation was banned across the class.
"Ararat" was constructed by Austal in Henderson, Western Australia. She was commissioned into the RAN in Melbourne on 10 November 2006.
