Americans have always been determined trail blazers, whether wading through the waist-deep tumbleweeds covering Arizona or hacking through the petrified forest of national flags on the moon.

Now privately owned, the USS Sequoia Presidential Yacht earned its name and national landmark status chauffeuring American heads of state since Herbert Hoover on missions and pleasure cruises. The 104-foot yacht motors down the Potomac River, framing a two-hour cruise past the city’s skyline with a collection of presidential memorabilia and Groucho glasses retrofitted with Richard Nixon’s nose. Built in 1925 by shipwright John Trumpy, the Jazz Age vessel glows with extensive wooden paneling, fine china, and brass sconces restored during a $5 million rehab. Climb to the breezy top deck to sip a glass of wine and lounge in the original teak deck chairs that Franklin D. Roosevelt and Winston Churchill used as stand-ins for a stoic Stalin in pre-Yalta practice negotiations. The dining room table bears a scar memorializing Harry Truman’s frustration during a poker game, and the bedrooms exhibit a chronology of personal photographs and personal effects from various former commanders in chief.
