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

On April 20, 2026, the Columbia River Bar Pilots conducted a MOB drill with the U.S. Coast Guard Station Astoria.

Wind Balance on straight track - using SAMMON to learn the theory and the effect of rudder and drift to reach the balance in steady state equilibrium conditions on straight track. Limits of steerability will be shown and how turn under strong wind.

Briese research are extending their cooperation with Nautitec for their research training projects. As from immediate effect, a model of the research vessel “Maria S. Merian” can be used for tailor made training at NAUTITEC´s Leer-based simulator facilities.

Many people wonder how ships made it across entire oceans without getting lost in the seventeenth century. Aaron introduces seventeenth century navigation to us today by beginning with piloting.

The technical body will bring together the extensive technical expertise and professional knowledge of Canada's licensed maritime pilots.
