Type C2 ship
From Wikipedia, the free encyclopedia
Type C2 ships were designed by the United States Maritime Commission (MARCOM) in 1937-38. They were all-purpose cargo ships with five holds, and U.S. shipyards built 173 of them from 1939-1945. Compared to ships built before 1939, the C2s were remarkable for their speed and fuel economy. Their design speed was 15.5 knots (28.7 km/h), but some could make 19 knots (35 km/h) on occasion. The first C2s were 459 feet (140 m) long, 63 feet (19 m) broad, and 40 feet (12 m) deep, with a 25-foot (8 m) draft. Later ships varied somewhat in size.
In 1937, MARCOM distributed tentative designs for criticism by shipbuilders, ship owners and naval architects. The final designs incorporated many changes suggested by these constituencies. The ships were to be reasonably fast but economical cargo ships which, with some government subsidies to operators, could compete with vessels of other nations. Building costs were to be minimized by standardization of design and equipment, and the ships were to have sufficient speed and stability that they could be used as naval auxiliaries in time of national emergency.
The basic specifications called for a steel cargo ship with raked stem and cruiser stern, complete shelter and second decks, and a third deck in Nos. 1-4 holds. Dimensions of the hatches were 20 ft (6 m) x 30 ft (9 m), except for No. 2, which was 20 ft (6 m) x 50 ft (15 m), allowing such cargo as locomotives, naval guns, long bars, etc. Ventilation to the holds was provided by hollow kingposts, which also served as cargo masts. Cargo handling gear consisted of fourteen 5-ton cargo booms, plus two 30-ton booms at Nos 3 and 4 hatches.
The ships could be powered either by steam turbines or diesel engines. The steam version had a high speed compound double reduction geared turbine developing 6,000 shaft horsepower.
Living accommodations were much improved over previous designs, with crew accommodations amidships, officers quarters on the boat deck, and the captain's quarters on the bridge deck, along with the wheelhouse, chartroom, gyro and radio room. Hot and cold running water was provided throughout.
Many variations of the basic C2 configuration were built, and many of the ships were converted by the U.S. Navy for service during World War II. The commercial versions were operated by the government during the war. Eight of the ships were lost during hostilities. Beginning in late 1945, the commercial ships were sold to merchant shipping lines.
Many C2 ships continued in naval or commercial service until the late 1960s and early 1970s.
