In this paper, the motion of partial air cushion support catamaran (PACSCAT) sailing in regular waves was firstly investigated by the experimental method. The monitored histories of heave, pitch, midship acceleration, and air cushion pressure in towing tests are performed to analyze the influence of air cushion on the periodicity feature of hull body motion. Subsequently, using the finite volume method (FVM)-based CFD software Star-ccm, numerical simulations are carried out for the PACSCAT model with a simplification of the air cushion system. The detailed flow information of wave evolution, pressure, and velocity distribution is investigated. The calculated oscillation characteristics of different motion parameters are compared with those from experiment and show good agreement. The numerical method also has good capacity in the prediction of amplitude response of heave and midship acceleration; however, large error is found when calculating resistance and amplitude response of pitch.

A nonlinear robust control strategy is proposed to force an underactuated surface ship to follow a predefined path with uncertain environmental disturbance and parameters. In the controller design, a high-gain observer is used to estimate velocities, thus only position and yaw angle measurements are required. The control problem of underactuated system is transformed into a control of fully actuated system through adopting an improved line-of-sight (LOS) guidance law. A sliding-mode controller is designed to eliminate the yaw angle error, and provide the control system robustness. The control law is proved semi-globally exponentially stable (SGES) by applying Lyapunov stability theory, and numerical simulation using real data of a monohull ship illustrates the effectiveness and robustness of the proposed methodology.
