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 . 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. Combat Fleets of the World mentions only 85 tonnes (84 long tons ). 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). The length is also recorded 29 m (95 ft).
