Views of President Harry Truman's new yacht, the USS Williamsburg, which serves as a floating White House and a means of recreation for President Truman. The yacht is readied for him. Exterior views and interior views of the 240 foot yacht are seen, along with a motor tender on the ship. A hand polishes a brass plaque that says "President's Quarters." It was built as a private yacht in 1931, and then converted to a gunboat before its conversion to become the President's yacht, replacing the USS Potomac.
