In February 1922, the Gibbs brothers started their own naval architecture firm, Gibbs Brothers, Inc.; their first major contract was to convert the former German liner
Vaterland into the American luxury liner . When shipbuilders
Blohm + Voss asked over $1 million for the original plans, Gibbs decided to draw his own. (1927) The Gibbs designed a series of four trim white-hulled ocean liners for the
Matson Lines service to Hawaii, starting with the design of in 1924.
Malolo was built at
William Cramp & Sons under the Gibbs Brothers' exacting supervision and tolerances. At the time she was launched,
Malolo was the largest and fastest passenger liner built in the United States. Three sister ships to
Malolo would be built in the 1930s: and in 1931 and in 1932. The
Grace Line contracted with Gibbs & Cox for four smaller 9,000-ton ocean liners in 1930, receiving the , , , and in 1932. Gibbs & Cox also designed the for the
United States Lines, which was completed in 1940. All nine of these ships served as U.S. troopships in the war. During the war, Gibbs & Cox created plans for thousands of American warships and cargo vessels, including
destroyers,
LST landing craft,
minesweepers,
tankers,
cruisers, and
Liberty ships. Between 1940 through 1946, 63 per cent of all merchant ships of 2,000 tons up and 74 per cent of all American naval vessels (destroyers, landing craft, escort carriers, etc.) were built to the designs or working plans of Gibbs & Cox. After the war, the Gibbs brothers were among the promoters for the US government and military to subsidize the construction and operation of a new 1,000-foot ocean liner. After overcoming resistance in the Truman administration for government involvement and competing designs, Gibbs & Cox was awarded the contract to design and supervise the construction of the . This ship was the culmination of Gibbs career, and he was fastidious in the incorporation of fire safety concepts, to the point that the
United States surpassed most present day passenger ships in fire prevention and containment. The design was also revolutionary in the use of lightweight materials and construction techniques, including a welded hull and aluminum superstructure. While rivaling the largest liners for physical size, she was much lighter, enabling higher speeds. The
United States entered service in 1952, after five years of design and 28 months of construction. On her maiden voyage, she won the
Blue Riband as the fastest ship to cross the Atlantic Ocean, averaging , and reducing the crossing time by 10 hours. Between 1952 and 1969, the ship carried a total of 1,025,691 passengers, and completed 800 transatlantic crossings (400 round trips), steaming a total of 2,772,840 nautical miles, and maintained an excellent safety record. She was the largest liner ever built in the United States and the fastest liner built anywhere. While fast and safe, she was panned by some passengers, as the use of exclusively fireproof materials in the décor and furnishings limited the aesthetic and luxury appeal. In remarks accepting the Franklin Medal for his work in designing the
United States, after recounting the ship's many achievements and the efforts of so many in making those achievements possible, Gibbs stated "
My sole contribution in this performance is the fact that I took the responsibility for failure." == Later years ==
