As explained, a large number of reports related to the use of pilot ladders which are too long relative to the vessel’s draughts. As a result, the excessively long ladders require shortening up before being deployed for boarding pilots. In these cases, ship crew shortens the pilot ladders, using D-shackles to choke the side ropes at the required height along the ladder’s length. In this method, the D-shackle is first secured to a hard point on the deck, such as a pad eye, and the ladder rope threaded through the shackle. Shortening ladders using the D-shackle method causes the weight of the ladder to be taken up by the D-shackle impacting directly against the mechanical securing clamps (widgets) which secure the ladders treads in place, Tokyo MoU explains.

There are many things in both our everyday and professional lives which we take for granted and never question the origins of, an example of this might be the IMPA recommended ‘pilot mark or pilot line’, which is sometimes seen on the side of vessels indicating where a vessels freeboard exceeds 9 metres.

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
