continued… A sign talked about how inland waterways regularly changed with silt, sandbanks, debris, ice floes, shifting channels, changing currents, changing depths with precipitation (or lack thereof), etc. In the 1800s, hundreds of river boats wrecked as a result of these difficult to foresee hazards. River pilots needed to be aware of subtleties such as the color of the water and the ripples and swirls to deduce potential issues. They also ran the boats at night, often illuminating the shore by suspending iron torches over the side of the boat. Unsurprisingly, a lot of boats burned down.
Lighthouses and lightships marked hazards and helped mariners to identify their exact locations on charts.

Dredgers removed excess silt and sand. Snagboats, first created in 1829, removed debris. If we understood properly, they dragged a line on the ground supported by winches. When then line caught on something, the winches would pull the line and debris that was caught on the line up.

The next exhibit was about fishing for a living. The first display was about cod fishing. The cod in what is now New England/Canada were huge. In the mid-1880s, they began to be harvested on an industrial scale. By the late 1880s, nearly 400 code fishing boats were based out of Gloucester, Massachusetts and the majority of fisherman were immigrants, particularly Portuguese.
