Hatch

A crewman walks along the deck on Herbert C. Jackson at Sault Ste. Marie, Michigan. He gives a sense of scale for the large hatches which occupy the ship's deck. Jackson's not a large boat by current standards, but she's certainly large enough to satisfy most of us.

Notice the sightseeing boat Chief Shingwauk in Poe Lock, beyond the Jackson (which is in Macarthur Lock).
