There were some astonishing pictures in the press some weeks ago of a Royal Marine employing a jetpack to launch himself from a RIB to land on the deck of a ship with extraordinary precision. You cannot imagine that it would be a feasible proposition to equip pilots with such a device, but it did cross my mind after reading a horrible catalogue of disgraceful seamanship and poor design exhibited in what ought to be the simple matter of keeping pilots safe as they board and leave ships.
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 can easily fail.
