ABSTRACT:
A rotor type energy saving apparatus mounted on the bow of a ship is disclosed for reducing the water resistance against the bow of a ship and converting the linear movement of waves into rotational movement to obtain an impelling force. Application of the apparatus results in a decrease in the amount of energy required to propel the ship. The apparatus has a conical shaped outer shell with blades running along its length and an inner means allowing the device to freely rotate. The apparatus is useful in reducing resistance and providing an impelling force on a variety of ships. It is best suited for use on small ships which have lengths under 45 meters.
