Suggested required reading for all mariners no matter where they work: on rivers, in open seas, in narrow passages or limited draft conditions. A good balance between theory and practical hands-on approach with excellent illustrated examples. Consists of three parts: 1) the ship's capabilities and its manoeuvring gear; 2) the forces which set the ship moving; 3) the ship as it manoeuvres (mooring, sailing in shallow waters, port manoeuvres, etc.).

Video Wind pure drift encounter - practical experiments for getting useful data
published on 8 July 2022
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!
