In this paper, a wave energy capture system for marine vessels is described. The system uses gyroscopic precession to create a relative motion within a vessel to generate power from the wave-induced roll and pitch motions. The governing equations of motion and a numerical model of the system are described in this paper and the behavior and performance of the system is identified. The system has several significant advantages over existing wave energy devices. For marine craft that operate in waves, the system could be very useful, providing a means to recover wave energy, reducing environmental impact, and improving operational effectiveness.
