NT Police Rigid Hull Inflatable Boat.  The Tactical RHIB is an 8.5 metre Gemini Waverider.  On this day it was patrolling around the Stokes Hill Wharf area and among the entrants of the Darwin Ambon yacht race as they waited for the start.  Note the new NT Police black uniforms worn in the Top End since July 2012.
