The difference between Gross Tonnage and Net Tonnage

At sea, space technology is used to help save lives every day: managing traffic between ships, picking up migrants and refugees in distress or spotting oil spills. The European Space Agency is once again at the forefront developing new technologies and satellites: to keep us safe at sea and to monitor the environment. Space makes a difference here on Earth and certainly at sea where there is no infrastructure.

'Shallow Water Effects' - The New KARCO video which promises to bring immense training value for navigators, has been developed using very effective 3D Animation &VFX.

A video by Capt. Pilot Nasir Khan, Pakistan
Why loud and clear communication is very important.

To monitor the vessel’s progress, the pilot had set up his portable pilotage unit (PPU). He had connected the rate-of-turn generator to the vessel’s pilot plug and had set a variable range marker on the radar with a radius of 0.5 nm.

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...
