Abstract
An improvement for inboard motor boats has a rigid exhaust conduit, a miniature rudder, and a rudder control system. The rigid conduit is provided for conduction of combustion gases exhaust outside the hull and has an aft facing outlet. The miniature rudder is pivotably mounted on the rigid conduit relative the aft facing outlet whereby combustion gases exhaust past the rudder. The rudder control system has a user interface inside the boat and has a control mechanism pivoting the rudder in response to inputs to the user interface.
Claims17
An improvement for inboard motor boats comprising:
- an inverted snorkel comprising a conduit for combustion gases exhaust extending outside the hull having an outlet aft of the transom;
- and
- an auxiliary source of thrust providing low-speed marine steering adjustments, said auxiliary source of thrust combined with the conduit for combustion gases exhaust extending outside the hull;
- wherein the auxiliary source of thrust comprises a drum motor and an auger affixed external of the of the drum motor.
An improvement for inboard motor boats comprising:
- an inverted snorkel comprising a conduit for combustion gases exhaust extending outside the hull having an outlet aft of the transom;
- and
- an auxiliary source of thrust providing low-speed marine steering adjustments, said auxiliary source of thrust combined with the conduit for combustion gases exhaust extending outside the hull;
- wherein the auxiliary source of thrust is electric powered;
- and
- wherein the inverted snorkel's conduit comprises one or more generally horizontal runs which singly or collectively terminate in and exhaust out through a terminal generally vertical run;
- whereby at least one of the one or more generally horizontal runs serves as a ground structure for side-aimed mounting of the electric powered auxiliary source of thrust;
- said improvement for inboard motor boats further comprising a mount for the electric powered auxiliary source of thrust for side-aimed affixation of the electric powered auxiliary source of thrust relative the at least one of the one or more generally horizontal runs.
