Education: Effect of Drift Force and unstable moment

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!

This video is an extract of some elements from lectures by Knud Benedict on "Simulation" as part of the seminars provided by the IALA World Wide Academy on the use of the "IALA Toolbox for Port & Waterway Risk Management".

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

Pilotage is being able to navigate safely into and out of a harbour/anchorage/port knowing where you are at all times, where your hazards are and a safe route in/out. This is particularly useful if you are heading into somewhere new or a challenging/busy area – or both!

This webinar is part of the Resilient Positioning Navigation and Timing Seminar Series.

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.

Here is the latest version of the professional handbuch of "pilot Ladder Safety" for the rigging and the use of pilot ladders by Herman Broers from July 2021.

Another worthful video by Knud Benedict, Germany

Editor's note: The pilot boarding seems a bit improvised and unsafe to me, but that's certainly business as usual, isn't it?
