Cristoforo Colombo was a screw corvette of the Italian Regia Marina (Royal Navy) built in the 1870s.
Characteristics
The design for Cristoforo Colombo was prepared by the noted naval engineer Benedetto Brin, and she was the first modern cruiser type vessel of the Italian fleet. Brin had originally intended to build a traditional sloop type cruising vessel, but a more powerful engine became available and Brin altered the design to accommodate it.[1] The ship marked a significant advance over earlier Italian screw corvettes.[2]
Cristoforo Colombo was 75.72 meters (248 ft 5 in) long between perpendiculars, and she had a beam of 11.3 m (37 ft 1 in) and an average draft of 5.25 m (17 ft 3 in). She displaced 2,325 long tons (2,362 t). The ship was of composite construction, with iron framing decks and wood hull planking. She was the last wooden-hulled cruiser of the Italian navy. The hull was divided into eight watertight compartments. She had a crew of 207.[1][3]
Her propulsion system consisted of a single marine steam engine manufactured by John Penn and Sons; the engine drove a single screw propeller. Steam was supplied by six coal-fired fire-tube boilers that were vented into a pair of closely-spaced funnels placed amidships. Cristoforo Colombo could steam at a top speed of 16 knots (30 km/h; 18 mph) from 3,782 indicated horsepower (2,820 kW). She had a fuel capacity of 630 long tons (640 t) of coal, which enabled a cruising radius of 4,160 to 4,480 nautical miles (7,700 to 8,300 km; 4,790 to 5,160 mi) at a speed of 13 to 14 knots (24 to 26 km/h; 15 to 16 mph).[1][3] To supplement the steam engines on extended voyages, she was fitted with a barquentine sailing rig.[1] The foremast was square-rigged, while the main and mizzen masts were gaff-rigged.[2]
The main battery for Cristoforo Colombo consisted of eight 120-millimeter (4.7 in) breech-loading guns, four guns per broadside. According to the Italian naval historian Aldo Fraccaroli, the ship probably had a 356 mm (14 in) torpedo tube installed later in the ship's career, though he provides no further details.[1]
