One might think that a ship is always in the water and that, consequently, it might not need a wash. Well you could not been more mistaken, just like I was about the pyramids on top of the Louvre and Piano. I wrongly attributed the structures to Renzo Piano and it was Steve who drew my attention to the mistake. By the way, great work Steve.
To start with, the ship is muled into the dock by its own windlasses or by the mules on the side of the dock (for those in favour of animal rights, don’t worry, they are mechanical). Once the ship is in and centered the door to the dock is placed and the water is slowly drained out.
Once the ship is down on the tressles it is now stable and will not move much.
Washing is the first thing the ship undergoes. This is to clean it from all anti-fouling and growth that would have attached itself since the last docking and which are a real deterrent to the ships own efficiency.
