The Smithsonian's collection of watercraft plans, maintained by the History of Technology Division of the National Museum of American History, is a valuable resource for the maritime historian, the student of naval architecture, other scholars, the model builder, and craftspeople. To make this collection more accessible to the public, black-line reproductions of many of the plans are offered for sale. The following three publications contain descriptions of plans and instructions for ordering large-scale copies; these catalogs are only available by writing to the address below. The catalogs and plans belonging to the Smithsonian Institution are copyrighted and may not be reproduced in any form without prior written permission.

Notice to Mariners

The majority of the Smithsonian watercraft plans are NOT original builder's plans. Most are the result of field documentation -- the process of taking the lines off historic vessels and half-hull models. Therefore, complete construction details and tables of offsets are not always available. Skilled naval architects and boat builders typically can develop tables of offsets from basic lines plans. In fact, we have heard from a number of boat builders who have built full-sized craft from Smithsonian plans. However, the Smithsonian cannot warrant the seaworthiness or safety of vessels built from its collection of study plans.

For questions on design drawings for specific vessels, please use the above contact form. We generally fill orders within four weeks of receipt.
