"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
What has the current experiences and developments in Maritime Pilotage Training been like? This session takes a global perspective at the conference. At the panel are: 🌊 John Barker, Senior Marine Pilot, Port of Auckland (New Zealand) 🌊 Captain Hanna Odengrund, Marine Pilot, Sweden Maritime Administration 🌊 Nurul Arrienne, Marine Pilot, Port of Tanjung, Malaysia 🌊 Fatouma Ali Ahmed, First Female Marine Pilot, Port of Djibouti 🌊 Reshma Nilofer, First Female Marine Pilot (India) 🌊...
This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship...
Understanding the fundamentals of the pivot point is highly required for understanding the alteration of the courses. Pivot point is an imaginary point on the vessel which turns on a circular path on the perimeter of vessel’s turning circle when the vessel makes a turn. The knowledge about the position of the pivot point in a manoeuvring situation provides the ship handler with the information on the geometry of motion of the ship.
Conapra's Technical Director, the pilot Porthos Lima, presented during the 53rd EMPA GENERAL MEETING the application developed for smartphones, inspired by the 2017 IMPA SECURITY CAMPAIGN. This tool allows pilots to report deficiencies in the Pilot Packing Arrangements and ship equipment, and these reports are instantly available to all Brazilian pilots. In the presentation Mr. Lima, representative of the Brazilian Maritime Pilots Association, showed how the App works and presented its...
