Spotted some Pilot Boats in the Port of Auckland, New Zealand and Melbourne & Fremantle Australia (Port codes: Auckland:NZ AKL ; Melbourne:AU MEL ; Fremantle:AU FRE).
It is frequently a Maritime requirement for a ship to employ and have onboard, a Ships Pilot when entering port. His/ her presence will greatly enhance the safe docking of a vessel into port, harbor or to an anchorage.
