Design & Technology

Incat’s latest generation craft have a payload carrying capacity almost
100% of the ship’s own weight.


Revolution Design’s team of naval architects, engineers and designers work with the concept and creative team at Incat to develop and refine vessel design. The team work together from concept through research and development, on structural design and analysis, drive line technical specification and layout, naval architecture services and complete drafting and design services for Incat vessels.

Research projects conducted in conjunction with vessel owners enable constant product development from an informed and accurate standpoint. The R&D team aims to improve ship design and ‘buildability’ with the continual goal of weight reduction, plus research into ways to improve operational reliability, efficiency and economy.

Incat’s latest generation craft have a payload carrying capacity almost 100% of the ship’s own weight. The high payload to vessel ratio has not been achieved by any other builder in the global high-speed light craft industry.

Incat and Revolution Design use Finite Element Modelling (FEM) to analyse design options and optimise both global and local scantlings in order to produce a weight efficient design without compromising strength.

A global FEM uses relatively coarse finite elements over the entire vessel structure to illustrate the stress behaviour under imposed design loads that are based on extreme sea conditions.

Local FEM models are then required to further evaluate stress distribution in ‘hot spot’ areas that the global FEM has highlighted as having high stress levels.


Constructed as a base vessel or SeaFrame, in line with the aviation industy’s AirFrame – the structure of an aircraft exclusive of its fittings – the craft can be fitted out for numerous purposes, including passenger/commercial, freight, offshore industry or military deployment.

Building to SeaFrame enables lower production costs and consequently lower ownership costs of Incat built Wave Piercing Catamarans.

Diesel engines or dual fuel reciprocating engines to utilise MGO and LNG are available from several manufacturers depending on client requirements for vessel size, power and speed. If higher speed is required dual fuel gas turbines are also an option.
The cargo/vehicle/mission deck, provides 797 truck lane metres (TLM) plus 148 cars, or 420 cars if required for a full passenger car mode, for high car capacity routes requiring high flexibility lifting mezzanine decks are an option.

Using the example of the Incat 112 metre SeaFrame, the vessel incorporates four diesel engines providing the 36 megawatts required to power the vessel at speed, ranging from a heavy load economy speed of 20 knots to 50 knots light.
Vehicle deck headroom is generally 4.5 metres, and with a beam of 30.2 metres, heavy road vehicles can easily turn in the bow for quick disembarkation over stern ramps.
