The difference between Gross Tonnage and Net Tonnage

This webinar is part of the Resilient Positioning Navigation and Timing Seminar Series.

Stabilisers are used to reduce the amount of roll experienced by large ships.
In this video, we look at a few different stabilisation techniques. We investigate how different methods work and how successful they are at reducing a roll.

It is not often that this blog is used to show bad practice, however in this case some pictures tell a whole story. Ship is compliant by design for rigging a combination. How about the operator(s)?

What happens when GNSS fails? In maritime navigation, this isn’t a hypothetical scenario – it’s a growing risk. Spoofing, jamming, and GNSS outages are increasing, especially in the Baltic Sea region. A failure can cripple navigation systems – with potentially serious consequences.

Pilot transfer arrangement is a sensitive topic to be discussed among the pilot’s fraternity. Although ships are designed and operated with compliance to the SOLAS requirements in all respects including the pilot transfer arrangements, there has been numerous deficiencies observed related to pilot transfer arrangements. The small deficiencies from the part of ships cause life threatening accidents for pilots and sometimes to the ship staff themselves. There are many instances of defective ladder and complacency in proper rigging of ladders has been reported almost every day in different parts of the world. Many pilots lost their life, severely injured for life and face many minor to major accidents. The latest incident being the Capt. Timothy Murray of Sandy hooks Pilot.

After a number of cruises in which I have watched with admiration and fascination as the harbor pilots do their magic. This is a short video showing the operation upon the departure of the Sapphire Princess from Kleipeda, Lithuania in the summer of 2026.
If you're inclined to help out my very tiny channel, subscribing tells YouTube to show the video in more people's feeds, and that means more people see the work I do. Sure, you don't have to, but if you do, THANKS!
