Constructed as a base vessel or SeaFrame, in line with the aviation industry's Air Frame - the structure of an aircraft exclusive of its fittings - Incat vessels can be fitted out for numerous purposes, including passenger/commercial, freight and military deployment. Building to SeaFrame principles enables lower production costs and consequently lower ownership costs of Incat-built Wave Piercing Catamarans. Incat’s 112 m SeaFrame incorporates four diesel engines to provide the 36 megawatts required to power the vessel at speeds ranging from a heavy load economy speed of 20 knots to 50 knots light. The cargo/vehicle/mission deck, provides 567 truck lane metres plus 216 cars or, 414 cars if required for a full passenger car mode. Vehicle deck headroom is up to 4.6 metres and, with a beam of 30.3 metres, heavy road vehicles can easily turn in the bow for quick disembarkation over stern ramps.
