Video Wind pure drift encounter - practical experiments for getting useful data
published on 8 July 2022
How to get information for wind & current limits to be potentially encountered by thrusters – or current? - this will be described in this movie:
- Measure Drift speed, due to beam wind with no propulsion;
- Measure drift speed using full thrusters
- Estimate wind & current limits to be potentially encountered by thrusters – or current...
- Finally there is a simple formula as Rule of Thumb: the transverse drift speed is about 7-8% of wind speed!

Article Results online survey into the securing methods of pilot ladders
by Herman Broers - published on 5 March 2021
It has been shown that a majority (51%) of pilot ladders is secured by means of D-shackles, when secured at intermediate length. 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.
