How AIS Works - Operation of AIS

Within seconds after the AIS MOB personal locator beacon easyONE-DSC is submerged into the water, the unit activates automatically and starts trasnmitting AIS and DSC alerts into vicinity of up to 7 nauticval miles.
You can also see the bright and strong red LED flare flashing which increases visibility of the victim in darkness drastically.

How LUXSPACE uses AIS messages to monitor worldwide shipping traffic

Matthias Meyer was head of the Bremerhaven port pilots, nautical expert and lecturer at maritime schools. In front of our camera, he voices what has long been a topic of discussion in shipping circles: that the 400-meter container ships have simply become too big for the narrow shipping channels of the Weser and Elbe. In his view, a serious accident is only a matter of time. We take a look at how the district is dealing with these giants and what politicians, BUND and shipowners have to say...

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

Practical samples for manoeuvres for ships going astern - as Stern-First-Method SFM. Introduction using as sample from the Master Thesis by Karel Wiegert for an arrival manoeuvre of a cruise vessel in Southampton port with a Twin-screw vessel under strong current. The same manoeuvre with the same ship model was used to show the advantage of Fast Time Simulation FTS using the SAMMON Planning Tool. This goes much faster than the manoeuvres in the real time simulator - and it can even be...

Manoeuvring large ships at close quarters and on shallow water is one of the most difficult aspects of shiphandling because of the complex hydraulic interactions depending on the ships' speeds, on the water depth and on lateral restrictions like in canals. Training is conducted both on meeting and on overtaking ships in shallow waters. This video shows how overtaking in a canal should be conducted: come in close to the stern and then move away from the bow that will be sucked towards your...
