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

This video explores the question of why ships are so difficult to manoeuvre in reverse.

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.

Join Great Lakes maritime historian and antiquarian Brendon Baillod as he discusses the restoration and conservation of a rare and very early 1865 Thompson's Great Lakes Coast Pilot. Early coast pilot books were kept on every schooner and steamer and Lakes and contain important details about the history of harbors, navigation, obstructions and shipwrecks on the Lakes. This 1865 Thompson's is among the rarest and also badly in need of stabilization. Enjoy this two part series where this...

This movie shows how to create the Characteristic Diagram for Wind effect on ships and limits of steerability under strong wind. It uses the previous demos made with the SAMMON Planning Software on turning tendency of ships on straight track and in turning motion.

Mungkin banyak sebagian dari kita masih asing dengan istilah Maritime Pilot . Padahal masa depan profesi ini sangat cerah. Kedepannya profesi ini sangat dibutuhkan baik di dunia pelayaran domestik dan internasional.
Untuk mendapatkan keahlian memandu kapal ternyata harus melalui beberapa tahap yang cukup panjang dan penuh tantangan.Simak pula perjalanan karir Capt. Akhmad Syaiful Salim sampai menjadi seorang Mariime pilot yang berhasil.
Semoga menjadi insiprasi generasi muda Indonesia....

Sea transport has for many years been a reserve of men with few women getting the opportunity, especially in most African countries. But for Fatouma Ali Ahmed, women can equally steer ships just as men can do.
