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.
The Australian company Hart Marine specialises in building pilot and patrol boats of the highest quality.This is not surprising, as the owner's father, Mal Hart, was a harbour master and therefore very familiar with the requirements of a pilot boat.
A portable pilot unit (PPU) is a portable navigation aid system designed specifically for ship pilots, such as the SIRIUS series from TRENZ in Germany (www.trenz-ppu.com).
