Design

The interceptor boats are of planing-type, designed by the L&T Marine & Ship Design Division, an in-house facility of Larsen & Toubro Limited. They are 30 metres long with 90 tonnes displacement and can achieve a maximum speed of 45 knots. The interceptor boats has full aluminum-alloy hull for reduced weight and is powered by twin water-jet propulsion systems to enable quick response. The vessels are fitted with state-of-the-art navigation and communication equipment and medium-range armament. Each vessel is powered by two Caterpillar Marine Power Systems 3516C marine propulsion engines (2525 bkW @ 1800 rpm, 'D' Rating) and two C-4.4 auxiliary generator sets (86 eKW @ 1500 rpm). The water-jets for the high-speed interceptor boats are being supplied by MJP Waterjets. Delivery of the water-jets began in 2010 and will continue until 2013.^[1] They are also fitted with MARIS ECDIS900 SmartLine Mk10 Flat Panel Computer with radar kit.^[2]

The vessel's crew consists of one officer and eleven personnel and are designed to perform coastal surveillance, search and rescue, anti-smuggling and anti-poaching operations in close coast and can also operate effectively in shallow water.
