The Kaivan (Persian: کیوان) is a class of large patrol craft operated by the Islamic Republic of Iran Navy. They ships in the class are modified versions of the American Cape-class vessels, built by the United States Coast Guard Yard in the 1950s.
Design
Sources cite displacement of Kaivan class vessels slightly different. According to Jane's Fighting Ships, the ships have a standard displacement of 100 tonnes (98 long tons) and 150 t (150 long tons) at full load.[1] Conway's All the World's Fighting Ships puts the numbers at 98 tonnes (96 long tons) and 148 tonnes (146 long tons) for standard and full load displacements respectively.[2] Combat Fleets of the World mentions only 85 tonnes (84 long tons).[3] The class design is 28.9 m (95 ft) long, would have a beam of 6.2 m (20 ft) and a draft of 2 m (6 ft 7 in).[1][2] The length is also recorded 29 m (95 ft).[3]
