Abstract
An outboard thruster for use in maneuvering a marine vessel at low speeds, particularly during docking or fishing operations. The apparatus includes a motor-propeller unit which is normally stowed aboard a vessel. The motor-propeller unit is lowered into a submerged position adjacent and outboard the vessel's bow to effect slow speed maneuvering of such vessel. When submerged, the direction of thrust produced by the motor-propeller unit can be controlled.
Claims4
Outboard thruster apparatus for use on a marine vessel, said apparatus comprising:
- a power-driven propulsion unit which when submerged provides thrust;
- support means carrying said propulsion unit;
- mounting means associated with the bow area of said vessel, said mounting means including a pair of generally vertically extending guide cables disposed on opposite sides of the bow area of said vessel, and a pair of legs affixed at their front ends to said support means and extending rearwardly from said support means to a slidable engagement with said guide cables;
- hoisting means on said vessel attached to said support means to raise and lower said support means and propulsion unit between a stowed position on said vessel and a submerged operative position;
- and
- steering means operatively interposed between said propulsion unit and said support means to direct the thrust provided by said propulsion unit in different horizontal directions relative to said vessel.
