"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
With the increasing accuracy and reliability of navigational receivers, this part of the video module will try to establish a better understanding of the mathematical definition of the Earth’s surface and mapping of this curved shape onto a plane surface.

In my announced sequel, the second part of GPS, it is primarily about the technical and physical operational and functional limitations to which GPS is subject. These limitations, in part, have serious implications for the accuracy of GPS, and even go as far as limiting the functionality of GPS in its functions or even making it impossible. In doing so,
The Good Practice Guide for Pilots 2021 describes the knowledge and skills (technical and non-technical) that the NZMPA believe all pilots should aim to achieve and maintain. It is written primarily for pilots for their own guidance and professional development, but can be used as a framework for pilot training, proficiency and assessment. It is referenced to NZ Maritime Law and Codes.
The Federal Bureau of Maritime Casualty Investigation (BSU) hereby announces the publication of the Investigation Report No. 285/20 on 26 October 2022. The report deals with the contact of the multipurpose ship ELSE with a closed lockgate of the Kiel-Holtenau lock which occurred on 29 August 2020.
The 16.3-meter aluminium pilot boat includes features aimed at performance and crew safety: • Twin Caterpillar C18 engines (2 x 400 hp) • Traditional shaft and propeller system • Top speed of 25 knots, cruising at 22 knots • Air suspension seats, autopilot, and interceptor system • Heated decks, rails, and windows • Crew accommodation for six • Galley for two and diesel heating for cold-weather operation • 2 x 1300-liter fuel tanks for extended range “This is not just a boat. This is a...
