A boat or ship (marine vessel) can be powered and propelled by using wind or solar energy. This propulsion results in the forward movement and six degrees of motion (roll, heave, pitch, yaw, surge, and sway) of the marine vessel. These motions have kinetic energy. This invention capitalizes on the fact that the solar wind and wave energy are cyclical by nature. The present invention enables the vessel to store energy harvested from these energy sources during periods when levels of energy is available from wind, solar, or the motion of the vessel in waves. This invention makes this stored energy available for use during periods when the external natural sources of energy (wind, wave, or solar) are not available in adequate quantities to maintain a reasonable speed of advance for the marine vessel. The harvesting of the energy during high energy cycles, storing it and using it when needed in this invention allows a marine vessel to get maximum speed of advance over a course. In this invention the marine vessel can maintain faster average speed without reliance on any fossil or chemical fuel and by only using renewable energy sources. In this invention the vessel is normally driven by wind channeling methods like canvas or foil sails or Flettner rotors. In addition to this, the vessel can be propelled by propulsion thrusters such as propellers, rim driven thrusters, azimuthing drives, water jets or other means of thrusting and propelling the vessel. These propulsion devices are driven by regenerative electric motors using stored electric energy in batteries on the vessel. The energy stored in the battery bank is used to provide supplemental or primary propulsion during cyclical periods when natural sources of wind, wave or solar energy are low. These same thrusters and their electric motors work in reverse to generate and harvest energy when wind levels are high and as the marine vessel is moving forward at higher speeds while being propelled by wind energy. In this invention the batteries, which are dense and heavy, to store this energy, are secured in the bottom of the marine vessel also serve as ballast to keep the vessel upright. This serves to lower the marine vessel's center of gravity to get the maximum hull stability for safety. This also helps the vessel channel maximum available wind energy to propel the vessel and harvest energy whenever stronger winds permit.
