Abstract

A reduced drag marine vessel providing a mechanism that will reduce or even eliminate the drag along the water-solid interface at the hull of the marine vessel. This mechanism is made up of a revolving elastic shell which is similar to a donut shaped belt. This belt forms an interior volume which houses rollers and a framework to support the tubular belt which can be further inflated with a gas to counter the hydraulic pressure of the water outside. Finally, this belt may be housed within a rigid outer tubular shell and contain a propeller within its center so as to form a marine nozzle.
