"Effect of Drift Force and unstable moment"

SAMMON - the IDEAL tool to identify manoeuvring capabilities of a ship - SAMMON - learning the EFFECTIVE way
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!
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
Lack of standard user interfaces across bridge equipment is a major concern for maritime safety. Pilots are in a unique position, as they are constantly exposed to new and differing bridge working environments, equipment, interface designs and combinations of systems. As pilots face this problem throughout every shift they need to put in considerable effort to adjust their work to the many user interfaces they meet.
Footage of the "Pilot Station Vessel" POLARIS of the Dutch Pilot Organisation, made with a DJI Phantom Drone, controlled with a FPV (First Person View), and equipped with a GoPro Hero 3 camera.
The location is Maascenter, an important navigation point for ships entering the Port of Rotterdam in the Netherlands.

Port operations, whether these are being performed on water or on land, are often not without risk. Pilots boarding a ship while sailing, navigating through narrow passages, collision avoidance with other smaller or larger vessels, discharging and moving cargo on land, walking between container handling equipment and trucks…
