I have seen this happen in person.  The large container ships displace a huge amount of water.  As the ship approaches the water level actually can rise at the shoreline because the ship is pushing so much water away from it.  It is basically plowing a hole thru the water.  As it passes the hole has to be filled back in with water and the level at the shore line drops.  I witnessed this about 30 years ago near my uncles place on the Chesapeake Bay.
