The USS Potomac (AG-25), originally built as the USCGC Electra in 1934 by the Manitowoc Shipbuilding Company in Wisconsin, is a notable vessel in American maritime history, primarily recognized for its service as Franklin D. Roosevelt's presidential yacht. Constructed as a wooden-hulled Coast Guard submarine chaser, Electra was commissioned in October 1934 and initially engaged in anti-bootlegging operations. In 1936, the ship was selected to serve as the President’s personal vessel, replacing the fire-prone USS Sequoia, and was subsequently renamed USS Potomac on January 30, 1936. During its conversion into a presidential yacht, approximately $60,000 was invested to upgrade the vessel, making it more luxurious and accessible, including the addition of a presidential stateroom, bath, guest cabins, teak decks, and a false smokestack housing an elevator designed for Roosevelt’s mobility needs. The vessel was equipped with a leather-furnished fantail, patio furniture, and bulletproof glass, making it a floating White House and political hub. The ship’s heavy rolling—up to 48 degrees in rough waters—was tolerated by Roosevelt, an avid sailor. USS Potomac served extensively during Roosevelt’s presidency, hosting fishing trips, informal meetings, and notable visits such as the first British royal visit to an American president in 1939. It was also used for clandestine wartime activities, including Roosevelt’s secret conference with Churchill in August 1941, where the Atlantic Charter was developed. The yacht played a vital role in wartime diplomacy, with Roosevelt often maneuvering the vessel for security reasons during the early years of World War II. After Roosevelt’s death in 1945, the vessel was decommissioned from Navy service and returned to the Coast Guard. Truman replaced her with a larger yacht, USS Williamsburg. Subsequently, Potomac was used as a fishery enforcement vessel, then sold into private hands and repurposed for various uses, including gambling and attempted conversion into a floating disco. It was involved in illegal activities in the 1980s, leading to its seizure and sinking at San Francisco’s Pier 26. Refloated in 1983, the vessel was restored by a nonprofit organization and is now preserved as a National Historic Landmark in Oakland, California. Today, the USS Potomac is the only remaining presidential yacht open to the public, serving as a museum and cultural site, with regular cruises and dockside tours, embodying a significant chapter of American maritime and presidential history.
