USS Potomac (AG-25), formerly USCGC Electra, was Franklin Delano Roosevelt's presidential yacht from 1936 until his death in 1945. In January 2016 the USS Williamsburg was scraped leaving USS Potomac and USS Sequoia as the last two still existing presidential yachts.[2] On 3 August 1941, she played a decoy role while Roosevelt held a secret conference to develop the Atlantic Charter. She is now preserved in Oakland, California, as a National Historic Landmark.
