The difference between Gross Tonnage and Net Tonnage

This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship...

Another very good explanatory video by Knud Benedict. Absolutely worth seeing.
Yaw Stability is an important element of Ships Manoeuvrability - both for course keeping and turning ability. This first video in a series explains the Basic Principles of stability in steady state equilibrium conditions and the forces / moments involved

This article was first published back in September 2021: Pilotage operations require close interaction between human and machines. This complex sociotechnical system is necessary to safely and efficiently maneuver a vessel in constrained waters.

The vulnerability of GNSS in shore-based use is definitely different and to be regarded as much more risky than on the high seas.

When the bow thruster has been in operation for a while, pilots often notice that the ship not only turns but also gains speed. But why is this? Opinion by Capt. Hugues Cauvier.

For the first time, a large vessel is to cross an ocean autonomously. The giant, developed by Hyundai, could usher in a new era of seafaringt: 300 metres long, 50 metres wide, with space for 180,000 cubic metres of liquid gas.

To boost efficiency of Yantian ship arrivals. The amendments represents the first time pilots from Hong Kong and Shenzhen have been allowed to navigate in the other’s respective waters, eliminating the need for a mid-ocean transfer of personnel.

According to a report from the Maritime-Executive.com the Crescent River Port Pilots Association wants to raise the pilotage fee.
