For the last ship of the day, I decided to stop at the Dossin Museum to catch her from the William Clay Ford pilothouse. There were a bunch of people in there, so I didn't really want to get many pictures of the pilothouse.
I did decide to take a picture of a ship's telegraph. This is used to communicate the desired speed to the engine room. The person in the pilothouse would click the desired speed and a similar telegraph in the engine room would receive it. The engineer would acknowledge the order and set the ship's speed to that.
