DESCRIPTION
A very nice detailed chart of Portsmouth Harbor, Massachusetts. This chart shows great inland details of topography by hachures, vegetation, farmlands, roads, buildings, facilities, and place names. Many aids to navigation are also shown such as buoys, courses, depth soundings, anchorages, rocks, ledges, and other dangers, bearings, lighthouses. Notes and Sailing Directions for Portsmouth Harbor. Tidal information along with currents also given.
IMPORTANT NOTE:
All of our United States Coast Survey (USCS), United States Coast & Geodetic Survey (USC&GS), and similar maps and charts have been professionally unfolded and flattened using humidity baths, semi-permeable membrane, and drying blotter techniques. Most others you typically see on eBay have not been, and worse, are quickly and crudely unfolded for the low-quality photos you see. Unfolding these maps in that way is damaging and weakens them. Please be aware.
