Working Sea Chart For The Approaches To Boston Harbor and Environs

Scarce sea chart of the area between Cape Ann and Duxbury, published by the United States Coast and Geodetic Survey in 1872, with corrections to navigational aids up toe 1882.

The chart is extensively annotated in a contemporary hand, with pencil notes showing the primary channels into the harbor, navigational notes and notes about several light houses and fixed lights.

Centered on the Boston Harbor, the chart provides a highly detailed navigational overview of the area, including extensive soundings, channels, islands, light houses, lighted buoys, islands, shoals and hazards.  On land, the map provides a fine overview of the topography, roads, major buildings, streets, harbors and other features.

The tables and notes around the chart describe magnetic variations, light houses, notes on how the chart was compiled from surveys dating back to 1846, as well as sailing directions, tides, soundings, buoys and other navigational aids.

Includes a stamp for the chart seller. "Michael Rupp & Co., Chronometer Makers and dealers in Charts, Sextants, &c., 29 South Street, New York."


The chart is relatively scarce on the market. This is the first example we have offered.

Condition Description
Blue backed chart. Several long tears, repaired on verso, with some staining at the right repair.
