The device of claim 10, further comprising a sheave crank arm mounted to said main drive sheave, said hydraulic cylinders being connected to said sheave crank arm by a rotating connection assembly. 12. The device of claim 10, further comprising gas pressurized hydraulic fluid accumulator tanks, wherein said hydraulic fluid is stored in said accumulator tanks prior to delivery to said hydraulic motor. 13. The device of claim 10, said counterweight member further comprising a line encircling assembly connecting said counterweight member to said line member between said anchor member and said buoyant member, said line encircling assembly allowing vertical movement of said counterweight along said line member between said anchor member and said buoyant member in response to vertical movement of said buoyant member. 14. The device of claim 13, wherein said line encircling assembly comprises guide pulleys receiving said line member. 15. The device of claim 10, wherein said main drive sheave and said line member mechanically interlock. 16. A wave responsive electrical generator device comprising: an anchor member;a buoyant member comprising a disk-shaped upper body and a lower body, the width of the lower body being less than the width of said upper body, a rotatable main drive sheave, hydraulic cylinders connected to said main drive sheave by a sheave crank arm, said hydraulic cylinders delivering hydraulic fluid through hydraulic conduits to a plurality of gas pressurized hydraulic fluid accumulator tanks, said accumulator tanks delivering hydraulic fluid to an hydraulic motor, said hydraulic motor driving an electric generator;a counterweight member comprising a line encircling assembly connecting said counterweight member to said line member between said anchor member and said buoyant member, said line encircling assembly allowing vertical movement of said counterweight along said line member between said anchor member and said buoyant member in response to vertical movement of said buoyant member; anda line member extending from said anchor member through said buoyant member and to said counterweight member, said line member being received around said main drive sheave, whereby movement of said line member resulting from up and down movement of said buoyant member relative to said anchor member causes rotation of said main drive sheave such that said hydraulic cylinders deliver hydraulic fluid to said hydraulic motor, which in turn drives said electric generator to produce electricity.
