West Kasson was a steam cargo ship built in 1918–1919 by Long Beach Shipbuilding Company of Long Beach for the United States Shipping Board (USSB) as part of the wartime shipbuilding program of the Emergency Fleet Corporation (EFC) to restore the nation's Merchant Marine. The vessel initially operated on the round-the-world route from the West Coast of the United States via East Asia and Spain before being shifted to serve the Gulf to Europe and South America trade in 1922. In 1926 she was sold to the W. R. Grace and Company and renamed Cuzco. In her new role the ship operated chiefly between the ports of the Pacific Northwest and various Chilean and Peruvian ports. In 1940 the ship was again sold and transferred into Panamanian registry and renamed Carmona. The vessel continued sailing between South America and the United States and was torpedoed and sunk by the German submarine on one of her regular trips in July 1942.

Design and construction After the United States entry into World War I, a large shipbuilding program was undertaken to restore and enhance shipping capabilities both of the United States and their Allies. As part of this program, EFC placed orders with nation's shipyards for a large number of vessels of standard designs. Most of these new vessels were known as the West ships as they were built by several shipyards on the West Coast of the United States and all were given names that began with the word West. Design 1019 cargo ship was among the designs adopted by USSB, and was a standard cargo freighter of approximately 8,800 deadweight tonnage designed by Theodore E. Ferris.

West Kasson was part of the order for eight vessels placed by USSB with the Long Beach Shipbuilding Co. on 10 July 1918 and was laid down on 15 October 1918 and launched on 15 March 1919 (yard number 130), with Mrs. John F. Craig, wife of John F. Craig, chairman of the board of directors of the shipbuilding company, being the sponsor. The launch was witnessed by a large crowd of 3,000 shipyard employees consisting of workers and management, and approximately 2,000 spectators. The vessel was launched approximately 80% complete with only her boilers and engine cylinders needed to be installed. Just as with many other vessels being built for the Shipping Board, her name was picked by Mrs. Woodrow Wilson who often chose Native American words for naming purposes.

Similar to all vessels of this class the ship had two main decks and was built on the three-island principle of ship construction. She had her machinery situated amidships and had five main holds which allowed for the carriage of a variety of goods and merchandise. The vessel also possessed all the modern machinery for quick loading and unloading of cargo from five large hatches, including ten winches and eleven booms. She was also equipped with wireless apparatus and submarine signal system and had electric lights installed along the decks.

As built, the ship was long (between perpendiculars) and abeam, and had a depth of . West Kasson was originally assessed at and and had deadweight tonnage of approximately 8,570. The vessel had a steel hull and a single 2,500 ihp triple expansion steam engine, with cylinders of , and diameter with a stroke that moved the ship at up to . The steam for the engine was supplied by three Scotch marine boilers fitted for oil fuel.

The four hour long dock trial was successfully held on 25 June 1919 after which the ship sailed to San Pedro. The sea trials were held on June 28 in the channel just outside the harbor during which the ship performed satisfactorily. Following their successful completion, the ship was delivered to her owners and officially accepted by them on June 30.

Operational history Under USSB control (1919-1925) Following delivery to the Shipping Board, West Kasson was allocated to the Pacific Mail Steamship Company, who inaugurated a round-the-world service to promote American shipping. The steamer then proceeded on her shakedown cruise to San Francisco for loading and arrived there on July 9. The next day the vessel was ordered to relocate for docking elsewhere and left her anchorage. During her trip West Kasson suddenly went on a spree of wild turns when the tiller apparently failed to obey the orders, and eventually the pilot was forced to order to stop the vessel and called in a tug to tow the ship to her new anchorage. Following this incident, the Shipping Board ordered the ship to have another trial trip which was conducted on July 18 and after its successful completion the ship was again accepted by USSB. West Kasson then loaded her cargo and departed San Francisco for Manila, Shanghai and Hong Kong on July 29. After visiting Chinese ports the steamer returned to Manila where she took on board a cargo of copra and from there proceeded to Java to load more of the same cargo and take it to Rotterdam. West Kasson reached her destination on November 23 and upon unloading her cargo left for Hampton Roads in ballast on December 4. The freighter was supposed to reach United States around December 15, but was unexpectedly delayed on her journey prompting widespread speculations about her fate. West Kasson finally arrived at Newport News on December 29, thus successfully concluding her five month long maiden voyage. Originally, the ship was supposed to stay in the Atlantic, but the high demand for cargo on the West Coast prompted the Pacific Mail Steamship Co. to send West Kasson west. She proceeded to Baltimore for loading in early January and after embarking 7,300 tons of general cargo sailed for California on 29 January 1920. After passing through the Panama Canal on February 5, the ship reached San Pedro on February 17 after largely an uneventful passage.

Following successful completion of a round the world scout trip through East Asia and the Mediterranean by West Kasson, Pacific Mail Steamship Co. decided to expand this service adding more vessels to the trade route. The freighter departed San Francisco for the inaugural round-the-world trip to a variety of ports in the Far East, India and the Mediterranean on 12 March 1920. She returned to Boston on July 30 bringing general cargo such as sugar from Java and cotton and skins from India to the East Coast ports. Upon discharging part of her cargo, West Kasson loaded at Boston and proceeded to New York and Baltimore to unload and load more cargo. She left Baltimore on September 4 and after passing through the Panama Canal arrived in San Francisco on 4 October 1920 successfully completing another round the world journey covering more than 28,000 miles in the process. West Kasson made one more round-the-world journey while under control of the Pacific Mail Steamship Co., returning to Baltimore on 11 March 1921 to discharge approximately 1,000 tons of manganese ore. On 10 April 1921 it was reported that the Pacific Mail Steamship Co. decided to return four large vessels, including West Kasson, to the Shipping Board citing lack of cargo in all of their foreign ports of service. The vessel arrived at San Pedro on April 20 and then proceeded to San Francisco where she remained berthed awaiting further assignment.

In June 1921 SS West Hartland who was supposed to take a large cargo of lumber to Japan collided with another steamer, SS Governor, and consequently was libeled and had to remain in port awaiting the trial. The Shipping Board dispatched West Kasson to Portland to take her place under control of the Pacific Steamship Company. After taking on board nearly 2,700,000 feet of fir and cedar lumber, West Kasson departed Portland on 5 July 1921 bound for Japanese ports of Kobe and Yokohama. Initially, the freighter was supposed to return directly to the West Coast, however, upon arrival in Japan at the end of July the vessel was rerouted to Singapore resulting in another round-the-world trip. West Kasson departed London for New York on 29 November 1921, however, on her way back 'she lost her propeller and was forced to put in into Bermuda on December 18 for repairs. She spent 59 days there being repaired before departing for Mobile on 15 February 1922. While in Bermuda, the ship was allocated to the Mississippi Shipping Company which operated two different lines from the Gulf ports, one to Le Havre, Antwerp and Ghent and the other to the east coast of South America.

After reaching New Orleans on February 22, West Kasson proceeded to load general cargo in several Gulf ports and cleared from Charleston on 5 April 1922 bound for Antwerp and Havre. She reached Le Havre on April 22 and after discharging her cargo sailed back to New Orleans in ballast on May 5. The steamer continued to operate from the Gulf ports of New Orleans, Mobile, Galveston, Port of Tampa and Charleston to Havre and Antwerp through 1926. She mostly carried cotton, wheat, case oil, phosphate rock and lumber on her transatlantic travels to Low Countries, usually returning home in ballast. For example, West Kasson arrived at Tampa on 20 March 1923 to load part cargo of 3,300 tons of phosphate rock for delivery to Dunkerque. Incidentally, on the same day the ship was raided by local law enforcement officers who confiscated between 6 and 7 pounds of opium. From mid 1923 through the end of 1924 she also made trips to various ports of Argentina, Brazil and Uruguay. For example, the ship left Port Arthur on 11 July 1923 loaded with case oil and rice bound for Buenos Aires and Montevideo. On her way back from South America she usually carried various agricultural and meat products as well as coffee. For example, the freighter left Brazilian ports of Rio de Janeiro, Santos and Vitória at the end of July 1924 carrying nearly 70,000 60-kilogram bags of coffee to New Orleans.

Early in 1925 the vessel returned to her travels to France and Belgium and sailed from New Orleans on 1 February 1925 fully laden with wheat, lumber and case oil bound for Le Havre and Antwerp. After discharging part of her cargo in Havre, West Kasson proceeded to Antwerp. On March 1 While docked there a fire ignited in her holds which burnt for several hours but was eventually contained. The ship suffered heavy damage amidships and had her entire engine room flooded, however, most of her cargo of wheat remained undamaged and was safely unloaded once the fire was completely extinguished. After completing all necessary repairs, the vessel departed Europe on April 18 for Mobile and arrived at New Orleans in May where she was returned to the Shipping Board.
