Abstract:
A floating vessel with gearless pod propulsor and counter rotating propellers is secured to a hull, each pod having a lead propeller and a trailing propeller, each propeller connected to a shaft connected to either a stator and rotor or a hydraulic motor. A lead propeller turns in a first direction and a trailing propeller turns in an opposite direction simultaneously, generating thrust for the floating vessel along a thrust vector using the counter rotation of the trailing propeller to recover swirling energy from the lead propeller improving propulsive efficiency of the floating vessel. The pod is positioned below a water line of the floating vessel providing propulsion for the floating vessel without gears.
