As illustrated here, the simplicity of the ancient design is maintained, though the materials used to build this modern version may well be more contemporary. For extra punch, the ' tree trunk ' could be hollow and an internal weight or shaft could impact a piston at the end as the thrust reaches it's maximum and comes to an abrupt halt ; especially when the mooring line goes taught after every wave.
"The G Whizz " as I'll call that G force factor ; Area B+, would also be transferred to a compressable hydraulic ram at each end of the ' tree trunk ' and impacting it would add a shot to the rest of the system. An electro-
magnetic coil around the cylinder could also utilize that movement and turn it directly into an electrical charge.
