This chart gives excellent navigational detail of Boston Harbor, with soundings, rocks, shoals, anchorages, and lighthouses noted. The chart was based on earlier surveys, including a US Navy survey from 1817 and British surveys from the Revolutionary War period. Drawn by Edmund Blunt and engraved by Hooker.

This map was published in the American Coast Pilot, a detailed guide to harbors, capes and headlands on the east coasts of North and South America including information on winds, currents, tides as well as latitudes and longitudes. The American Coast Pilot was published in 21 editions between 1796 and 1861, until it was replaced by federally-funded charts produced by the US Coast Survey.
