I'm always amazed how these tugs control those big barges!

It's pretty impressive.
An indication of the force required for the tug to control the barge
is the size of the pins the tug uses to connect. The specs I saw once
were 31 inch diameter for the pins. Yikes! There must be a better word
than 'pin' for something that big.
