USS Potomac - FDR's Floating White House

The USS Potomac was built in 1934 as the Coast Guard cutter Electra. The 165-foot vessel, weighing 376 gross tons and cruising at speeds of 10 to 13 knots, was commissioned as a U.S. Navy vessel in 1936, renamed the USS Potomac, and served as Franklin Delano Roosevelt’s presidential yacht until his death in 1945. As former Assistant Secretary of the Navy, FDR had a deep love of the sea and the Navy tradition. He hated to fly and preferred to travel by train or ship throughout his presidency.
