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

[edit]

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]
