"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
Knot your average day job.

Fremantle Pilots respectfully acknowledges the profound connection that exists between the land, waterways, and the traditional lands of the Whadjuk people. We pay our deepest respects to the Whadjuk people, the original custodians of the expansive Walyalup region, and recognize the enduring significance of their cultural heritage and beliefs in shaping the present and future of the Whadjuk...
Amid the breathtaking beauty of Tampa Bay, there is a constant current of change for the Tampa Bay harbor pilots. In an ocean that can turn from peaceful to perilous, the pilots are required to have a calm voice and a steady hand.
“You really do have to know how to work under pressure. You’ve got to be quick on your feet. You’ve got to be on point all the time,” pilot Tevin Freeman said.
