A handy and simple tool to determine in a minimum time what is really needed as tug assistance, is the Bollard Pull Calculator which calculates in an approximate way the total required tug power for ships in various conditions of wind and current. This tool can be loaded as an app on the smart phone.
The Maryland Pilots have guided ships to and from Baltimore since the 1700's. They have been chartered as an organization since 1852. This is an edited except from films about the Pilots shot between 1950-1965 for the Port that Built a City and State. The original films are in the archives of the Baltimore Museum of Industry.
Shortly after 5 a.m. local time the vessel “Else” had a collision in the Kiel-Holtenau lock to the Kiel Canal.
The "Else" subject to pilotage passed the pilot's boarding position without taking a sea pilot on board and collided from the outside into the closed gate of the new north lock. The bow bored into the metal construction and the ship was stuck for about six hours.

Editors note: A film of a pilot boat has just been published on YouTube with the title "How Dangerous being in a Pilot Boat..." on YouTube. I'm not sure if this really shows a dangerous maneuver, maybe the experts can comment on it here.
But in principle it is problematic to approach the ship in such a small Pilot Boat in the wake from astern and cross the waves there. I remember an accident from Finland in December 2017 where the boat capsized and people died. Is this situation shown here...
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!
