The original plans of the pioneer transatlantic steamer Savannah no longer exist, and many popular representations of the famous vessel have been based on a 70-year-old model in the United States National Museum. This model, however, differs in several important respects from contemporary illustrations.
To correct these apparent inaccuracies in a new, authentic model, a reconstruction of the original plans was undertaken, using as sources the ship's logbook and customhouse description, a French report on American steam vessels published in 1823, and Russian newspaper accounts contemporary with the Savannah's visit to St. Petersburg on her historic voyage of 1819. The development of this research and the resulting information in terms of her measurements and general description are related here.

The recent naming of an atomic-powered ship in honor of the famous steamer greatly increased popular interest in the pioneer ship and its supposed model. Consequently, the National Museum undertook the research necessary to correct or replace the existing model. This research has been carried out by the staff of the Museum's transportation division with the aid of Frank O. Braynard of the American Merchant Marine Institute, Eugene S. Ferguson, curator of mechanical and civil engineering at the Museum, and others.

Figure 1.—Old model of the Savannah , built under the supervision of Captain Collins. This model has been removed from exhibition in the United States National Museum because of inaccuracies. ( USNM 160364; Smithsonian photo 14355.)
The old, inaccurate model, built to the scale of one-half inch to the foot, represents an auxiliary, side-wheel, ship-rigged steamer. The model scale measurements are about 120 feet in over-all length, 29 feet in beam, and 13 feet 6 inches depth in hold. The tonnage is stated on the exhibit card to have been about 350 tons, old measurement. The model has crude wooden side paddles of the radial type, a tall straight smokestack between fore and main masts, a small deckhouse forward of the stack, a raised quarter-deck, and a round stern.
