"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
This video provides the detailed explanation of the phenomenon showed in Part 1 of this topic and a solution for this problem at the end. This phenomenon was recently disocovered by Dr. Steve Shaojie Tang and published in his book by Faiteve inc in 2018.

Manoeuvring large ships at close quarters and on shallow water is one of the most difficult aspects of shiphandling because of the complex hydraulic interactions depending on the ships' speeds, on the water depth and on lateral restrictions like in canals. Training is conducted both on meeting and on overtaking ships in shallow waters. This video shows how overtaking in a canal can easily fail.

The Svitzer Marloo, a Z-Tech 2800 ASD Tug, is one of the few vessels in the world to regularly use the complex and potentially dangerous Centre Lead Forward manoeuvre to assist inbound and outbound bulk carriers in the execution of a 110 degree turn on entering and leaving Port Kembla. Tug Master Phil Jones explains how a dangerous maritime exercise, if properly executed, can deliver...
