The combination of the sailing space frame and the vessel to be propelled turns the combination into a Proa configuration, where a Proa is a typically a small sailing canoe, having a sail, with an attached outrigger on one side primarily used in the past for ocean passages by islanders living in the Pacific Ocean. The outrigger allows the Proa to carry a sail area much larger than the canoe could carry without the outrigger. In this invention the vessel to be propelled is like a large canoe, and the sailing space frame provides the outrigger, as well as the needed sails, rudder, and dagger board components needed to convert the coupled vessel into a viable sailing vessel. The large sail area provided by the sailing space frame for the propelled vessel allows propulsion of the cargo or tanker vessel under sail power, without the need for operation of the vessel’s diesel engines for propulsion purposes. The energy requirements for the operation of the TankerProaTM are minimal, due to the balance design of the sails and dagger board rudder, and outrigger components, and are all provided by wind, wave, and solar sources.
