A power-generating device located in or on the surface of the ocean for generating power utilizing the energy in ocean wave motion. The device is moored to the bow and stern at ˜45° to incoming ocean waves, and with a yawing capability to adjust to change in wave direction. The device delivers power to a shore grid via a submarine cable from a generator. A rotational driving torque to the generator is produced by two long counter-rotating drive tubes, which are held by bearings in the bow hull and the stern hull of the device. As an alternative, hydraulics may be employed for energy capture and power smoothing and used to provide the rotational torque through a hydraulic motor to drive a generator. The main body is partially submerged and has multiple pod floats connected to the structure by rocker arms with bearings through which the drive tubes pass or double-acting hydraulic rams between the arms and the main body, which capture energy through pod displacement and store it in accumulators. Rotary torque of the drive tubes is produced when the pods move up and down according to motion of the waves and is transmitted to the generator to generate power. In the hydraulic case, energy is stored in accumulators as pressure due to the double-acting hydraulic pistons pumping when the pods move up and down according to the motion of the waves. Hydraulic pressure drives a pump, which provides torque to the generator.
