nave mercantile WW1 USA costruita in 750 navi con scafo in.... legno.
da sito sopra indicato: In April 1917, after much debate, the United States entered World War I, which had been raging in Europe for nearly 3 years. It very quickly appeared to the U.S. Shipping Board (USSB) that the country would not have enough ships to bring supplies, food, and ammunition to support the U.S. troops, especially in view of the effectiveness of the German U-Boats. The Emergency Fleet Corporation (EFC) therefore decided to contract for 703 wooden cargo steamships to supplement its budding fleet of steel cargo ships. This created great controversy; at the time, wood was already obsolete for large ship building, and even reciprocating steam engines were considered old-fashioned. The main type of wooden ship followed the Theodore "Ferris" design (USSB design #1001), a 270' long, coal-fired, "three-island" ship of 3,500 deadweight tons.
