I have been living on Tybee over three years now and I am still fascinated by the massive size of the container ships that go up the river. This is a photo taken yesterday afternoon of a container ship as it rounded a point on the island. The ship is fairly close to the shore. To determine scale look at the people on the beach (aka the tiny dots). You can also look at each of the containers on the ship and recognize that they are semi truck trailers.
Here is an older close up of a container ship with a tug boat in front of it. Perhaps it is even better to determine scale. You can see the tug’s captain if you look closely in the window.
