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.

During the transit time on the pilot launch between the shore and the vessel, marine pilots will spend at least a portion of that time carrying out (either consciously or subconsciously) a risk assessment of the forthcoming operation.

Over the past few years a number of pilot transfer accidents have occurred resulting from total failure of the side ropes, one school of thought is that the methods of securing a pilot ladder is a factor in such occurrences.

The latest summary from PTR Holland on the subject of pilot ladders. Here is the most important information on maintenance, use and replacement & insepection record book.

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

The vulnerability of GNSS in shore-based use is definitely different and to be regarded as much more risky than on the high seas.

From "Casual Navigation": In this video, we investigate the Pilot Ladder. It is a crucial piece of equipment, used for embarking and disembarking a harbor pilot at sea.(contains advertising)
