Nautical Charts

The Atwood House & Museum’s chart collection, the most extensive of any museum on the Cape or Islands, is part of Chatham’s maritime heritage. This collection consists of about 130 charts, mostly from the 19th century. Many of the charts were used by Chatham sea captains, and were donated to the Atwood House Museum by Chatham residents.

A significant number of the charts in the collection have been identified with specific Chatham shipmasters, including Captains Gershom Jones, Charles W. Jones, Simeon Taylor, John Taylor, Cyrus Eldredge and Charles W. Hamilton. Certain of these charts were used aboard sailing and steam ships named: Revere, R. M. Heslin, Sylph, SS Kin Kiang, SS Mississippi, Thordis and Red Cloud. Pencil notations by mariners reveal details of specific voyages (including daily navigational fixes) as the courses were plotted.

In the collection are “Blueback” charts published by British firms (Imray, Norrie, Laurie, Chas. Wilson), as well as charts published by the British Admiralty, the U.S. Navy Hydrographic Office, private Dutch companies, the US Coast Survey and the private firms of Chas. Copley and E. & G. W. Blunt.

The collection also features several charts produced by George Eldridge and his son, George W. Eldridge. The story of the Eldridges, father and son, is told in an exhibit in the Wendy Wade Costello Gallery on the lower level of the Museum. “Chart George” Eldridge, born in Chatham in 1821, established one of the two most exceptional private chart-producing enterprises in America. While smaller than that of the Blunts, it was more innovative and longer lasting. His first chart, the famous 1852 “Eldridge Upside-Down Chart” of Monomoy Island and the nearby shoals (south is to the top), is displayed in the Wendy Wade Costello Gallery exhibit, and can also be viewed on this page in our Nautical Charts Virtual Gallery.

Nautical Charts Digital Collection

Forty-one of our charts have been professionally restored and digitally imaged. These digital images are exhibited online on the Atwood House & Museum’s Nautical Charts Virtual Gallery pages. This initial phase of the Chatham Nautical Chart Initiative has been completed with support from a grant from the Town of Chatham through its Community Preservation Committee.

The digital images in our collection are permanently maintained by the Digital Commonwealth on their website. Digital Commonwealth is a non-profit collaborative organization of over 130 member institutions devoted to the creation, management and dissemination of cultural heritage materials held by Massachusetts libraries, museums and historical societies. The charts in our collection were digitally imaged by Digital Commonwealth at their facilities located in the Boston Public Library and are displayed on their Massachusetts Collections Online pages.
