The difference between Gross Tonnage and Net Tonnage

In fact, the pivot point that we “see” is a trick of the eye, it looks like the ship is rotating about this point but in fact it is elsewhere, a point that you cannot see.

How to get information for wind & current limits to be potentially encountered by thrusters – or current? - this will be described in this movie:
- Measure Drift speed, due to beam wind with no propulsion;
- Measure drift speed using full thrusters
- Estimate wind & current limits to be potentially encountered by thrusters – or current...
- Finally there is a simple formula as Rule of Thumb: the transverse drift speed is about 7-8% of wind speed!

During a meeting on 4 December 2024, the International Hydrographic Organization Nautical
Information Provision Work Group (IHO NIPWG) held a vote on the new Guide for Nautical
Data 2.1. The guide was unanimously endorsed.

This video explores the question of why ships are so difficult to manoeuvre in reverse.

This movie shows how to create the Characteristic Diagram for Wind effect on ships and limits of steerability under strong wind. It uses the previous demos made with the SAMMON Planning Software on turning tendency of ships on straight track and in turning motion.

Roberta Cotta and Teresa Matarese are the only two women in the Italian Federation of Harbour Pilots (Fedepiloti) team of 212 professionals.

In this part two video of the man overboard drill series. In one continuous take and no speed adjustments. You can see once the dummy is launched in the water. How fast the crew can come to a complete stop. The boats captain moves to the stern control station, Deploy the stern scoop and rescue the survivor. All of this happing in less than two minuets. An amazing display of teamwork and skill. Filmed using a DJI Mini 2 If you are interested in purchasing a Mini here is a link to my DJI...
