Halifax Traffic

The cold morning air of early winter calmed the harbour water just as
 a large container boat arrived at Halifax. 

Two strong tugs worked together turning the massive ship and its precious cargo. 
Working together they turn the ship and push her back to the wharf. 
I sketched the dance as quickly as possible. 
After docking the massive shore cranes take over the task of unloading and loading steel containers filled with products from around the world.
