"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
The Making of a Bay Pilot
Allen Garfinkle, Executive Director, Board of Pilot Commissioners, San Francisco, San Pablo and Suisun Bays
Professional mariner Captain Allen Garfinkle, will highlight the role of maritime pilots in waterborne commerce on San Francisco Bay, including how one becomes a maritime pilot, dangers of the job and common myths about piloting on the Bay. Captain Garfinkle is the Executive Director of the state level authority that trains, licenses and regulates those pilots....
