For any directed sea waves the rocking propelled ship can reach high speeds if it utilizes an sea waves energy by means of 1. A rocking propulsor, which is a couple of hydrofoils kept elastic cross by pivots on the extreme points of streamline narrow keel-rocker, extended far out off long sizes of the ship and thus wags hydrofoils vertically with a speed and an amplitude being sufficient for its proper work; 2. A "pendulum design" of a rocking propelled ship, described by a light wide body with weight, concentrated in a middle lowest ship's part and having a vertical keel with a heavy bob. This design provides the highest efficiency of an energy transmission from waves to ship rocking. In case of need to increase ship's speed some more its rocker should be rigged by an on-board oscillator, which is a central heavy flywheel, which is alternately twisted up to speed by a serve motor in both directions on cross axle in time (resonance) of ship rocking. In order to accelerate and change revolution directions without energy loss the flywheel is supplied by spring returners. If the ship is assigned to navigate in both sea state cases (high or calm) the oscillator is mounted into the rocking propulsor, which is attached to the ship bottom with a hinger. It can be locked to the bottom to be swinged by a rocking ship hull to propell the ship by wave generated rocking motion. It can be unlocked to be swinged by the board oscillator undependently from the ship hull to propel the ship in case of calm sea.
