USS Potomac (AG-25), formerly USCGC Electra, was Franklin D. Roosevelt's presidential yacht from 1936 until his death in 1945. On August 3, 1941, she played a decoy role while Roosevelt held a secret conference to develop the Atlantic Charter. USS Potomac and USS Sequoia are the last two existing U.S. presidential yachts, after USS Williamsburg was scrapped in January 2016. Potomac is now preserved in Oakland, California, as a National Historic Landmark and the only presidential yacht open to the public.
