Abstract
A wave motion energy harvesting apparatus of the invention comprises a float portion detachably interfitted with and axially moveable with respect to a hydrodynamically resistive portion. The float portion of this apparatus is moored by means of a line attached adjacent its vertical axis, but the hydrodynamically resistive portion is neither anchored nor moored except by its being interfitted with the float portion. Both the float and the hydrodynamically resistive portions are separately configured to have their mass distributed evenly about a common vertical axis of the apparatus. The float portion of the apparatus is nearly neutrally buoyant and comprises an automatically filled water ballast tank.
