Drydocking or undocking is always a difficult task, particularly with a “dead” vessel (no power/propulsion) and the wind blowing on the ship's side.

Today I will discuss a very simple and useful practical trick often used by pilots.

When we have to berth a vessel with small clearances forward and aft (say 20 to 25 mtr fwd and aft) it is very essential that you are able to estimate your position. Now most of the time you have a berthing supervisor on jetty who will help you with position.

How do marine pilots work? Example: Bringing a bulkcarrier alongside to „Hansaport“ in Hamburg. Here the tugboats „Prompt“, „Resolute“ and „Bulldog“ are involved. The master has to rely on the pilot. One reason is, that he can‘t know how to deal with these tugs. A maneuver like this is only safe, when the pilot has a lot of practical experience. A master who is doing a maneuver like this only about once or twice a month and each time with tugs he doesn’t know in areas he hasn’t been to...

This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship...
