Previous research (Evans, 2020) has proven that this method has only about 50% of the strength of the pilot ladder when secured at full length (“double ended ladder”), or by means of the “endless-sling” method.

Correct method of rigging pilot ladder explained.
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 this method, the D-shackle is first secured to a hard point...
