Various examples of simultaneous ocean wave and current energy harvesting are described, using a hybrid ocean energy converter and a mechanical transfer system therefor. In one example, a hybrid ocean energy converter includes a two-body point absorber comprising a first body and a second body. The two-body point absorber can be configured to transfer a linear relative motion between the first body and the second body to bi-directional rotation of a first input shaft. A turbine can be configured rotate a second input shaft. The converter further includes a hybrid power takeoff including a mechanical transfer system configured to mechanically couple the first input shaft, the second input shaft, an output shaft, and an output shaft.
