The SS President Hoover was an American ocean liner commissioned by Dollar Steamship Lines and completed in 1930. It was notable for being the largest merchant ship built in the United States at the time, constructed by the Newport News Shipbuilding and Drydock Company in Virginia. The vessel featured turbo-electric transmission, powered by a pair of steam turbo generators—built by General Electric—driving twin propulsion motors that produced approximately 26,500 shaft horsepower at 133 RPM. Its design included luxurious accommodations that were air-conditioned, with a telephone in every cabin, and amenities such as swimming pools, gymnasiums, a dance floor, and Otis elevators. The décor was in the Art Deco style, with the First Class lounge adorned with murals by artist Frank Bergman. The President Hoover served a trans-Pacific route between San Francisco and Manila, via Japan and China, primarily carrying passengers and mail subsidized by the U.S. Postal Service. She launched on December 9, 1930, with First Lady Lou Henry Hoover christening her, and her maiden voyage soon followed. She and her sister ship, President Coolidge, represented the pinnacle of American merchant shipbuilding until their service was affected by regional conflicts and changing travel patterns. Notably, the ship’s service was marked by a dramatic incident during the Sino-Japanese War. In August 1937, while en route to Shanghai, President Hoover was mistakenly attacked by Chinese aircraft despite her neutral American status, suffering minor damage and casualties. Later that year, on December 11, 1937, amid poor visibility and a heavy monsoon, she struck a reef off Kasho-to (Green Island) near Taiwan while attempting to navigate an unfamiliar route. The ship was torn open at the stern and came to rest with a slight list, prompting an emergency evacuation involving crew, villagers, and Allied naval ships. The vessel was eventually abandoned and became a total loss, with salvage efforts beginning in 1938. The wreck of the President Hoover became a significant maritime event, symbolizing the dangers of navigation in wartime and the challenges faced by American merchant shipping in turbulent times. Her sinking marked the end of her distinguished service and contributed to the maritime history of American ocean liners of the era.
