The second season of the Australian drama Sea Patrol premiered on the Nine Network on 31 March 2008 and aired on Monday nights at 8:30 PM. The thirteen-episode season ended on 23 June 2008. The season introduced a new patrol boat, following the decommissioning of the original, Fremantle-class boat in the final scenes of season one. The new HMAS Hammersley (hull number 82) was of the Armidale class, reflecting the real-life changeover in the Australian fleet. The second season also featured the debut of a new main character, Able Seaman Rebecca "Bomber" Brown, as the boat's new cook.
