The hull drive system is composed of a looped steel rail TRACK onto which the wheeled carriages are attached. Each CARRIAGE is suspended underneath the track, like a carriage on an urban monorail system. By using electric MOTORS to drive the carriages and nitrogen filled rubber tyres on the rails, noise is virtually eliminated. The hull is attached to the carriage by HYDRAULIC actuators which then move each hull to make changes to the wave size and shape. Software controls the speed and the draft and the angle of each hull. Small changes in these three elements, brought about by the software, result in immediate changes to the wave size and shape.
