Baltimore Inner Harbor Nautical Chart
The Patapsco River carries a deep, well-marked shipping channel from the Bay all the way to the Inner Harbor. The chart shows the Brewerton and Fort McHenry channels, commercial anchorages, and the tight marina basins of Canton and Fells Point. Stay clear of the ship channel and mind security zones around the port terminals.
