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.[3] Potomac is now preserved in Oakland, California, as a National Historic Landmark and the only presidential yacht open to the public.
