Harbour Pilot boarding on ship with Pilot ladder

KITTIWAKE ( MMSI 232008570) is a Pilot and currently sailing under the flag of United Kingdom (UK) Here she is speeding down the River this morning.

Vessel name: Polaris ; Year built: 2012 ; Flag: Netherlands ; Homeport: Rotterdam Length: 81.2m X 13.3m ; GRT: 2501 ; Callsign: PBZN ; MMSI:245142000 ; IMO: 9496915 Type: Special Vessel / Pilot Ship A "Pilot Ship / Pilot Vessel" is a "special type" of ship in which it accommodates a certain and limited Marine Pilots (Sea, River, Harbor Pilots), it also carries small boats/crafts that are used to tender services to and from the Pilot ship. In a Pilot Vessel, the Pilots can take their time...

According to a report today by www.MaritimeBulletin.net a mooring boat was rammed from a container ship and sunk.

pilot boat is a type of boat used to transport maritime pilots between land and the inbound or outbound ships that they are piloting. Pilot boats were once sailing boats that had to be fast because the first pilot to reach the incoming ship 

This video shows an introduction on the Spiral-Test-Manoeuvre and describes the procedure how to steer through this manoeuvre and measure the data needed. The results will be displayed in a characteristic diagram allowing to identify stable and unstable conditions and related, detailed information, e.g. spiral loop width and height, rudder angle of neutral effect. Samples of stable and unstable ship behaviour demonstrations will be shown by Fast Time Simulation using the SAMMON Planning tool.

Exemplary manoeuvre: The pilot should always walk on the side of the pilot boat facing away from the vessel. This prevents the pilot from being trapped between the two vessels in the event of a fall into the water.

This important topic is still underestimated in shipping! Can you trust your GPS? Your Galileo? Knowing where the ship is and where to sail next is the main task of navigating a ship and is commonly supported by using Global Navigation Satellite Systems (GNSS). But what happens if the GNSS gets intentionally disturbed?
