Abstract

Claims (37)

1. A stowable propulsion system for a marine vessel, the stowable propulsion system comprising:

a base configured to be coupled to the marine vessel;

a propulsion device configured to propel the marine vessel in water; and

a shaft that extends along a length axis and pivotably couples the propulsion device to the base;

wherein the propulsion device is pivotable into and between a stowed position and a deployed position, wherein pivoting the propulsion device causes the shaft to rotate about the length axis, and wherein the shaft is configured such that rotating the shaft causes the propulsion device to pivot.

2. The stowable propulsion system according to claim 1 , wherein pivoting the propulsion device towards the deployed position rotates the shaft about the length axis in a first direction and pivoting the propulsion device towards the stowed position rotates the shaft in a second direction that is opposite the first direction.

3. The stowable propulsion system according to claim 1 , wherein the shaft pivots about a transverse axis that is perpendicular to the length axis about which the shaft rotates.

4. The stowable propulsion system according to claim 1 , wherein the shaft is rotated via a gearset when pivoting.

5. The stowable propulsion system according to claim 1 , further comprising an actuator that pivots the shaft into and between the stowed position and the deployed position.

6. A stowable propulsion system for a marine vessel. the stowable propulsion system comprising:

a base configured to be coupled to the marine vessel;

a propulsion device configured to propel the marine vessel in water; and

a shaft that extends along a length axis and pivotably couples the propulsion device to the base. wherein the propulsion device is pivotable into and between a stowed position and a deployed position, and wherein pivoting the propulsion device causes the shaft to rotate about the length axis; and

an actuator that pivots the shaft into and between the stowed position and the deployed position, wherein the actuator extends and retracts to pivot the shaft into and between the stowed position and the deployed position.

7. The stowable propulsion system according to claim 6 , wherein retracting the actuator pivots the shaft towards the deployed position.

8. The stowable propulsion system according the claim 5 , wherein the actuator concurrently rotates the shaft about the length axis as the shaft pivots between the stowed position and the deployed position.

9. The stowable propulsion system according the claim 1 , wherein the shaft pivots 90 degrees and rotates 90 degrees about the length axis between the stowed position and the deployed position.

10. A marine vessel comprising:

a deck; and

a stowable propulsion system suspended from the deck, the stowable propulsion system comprising:

a propulsion device configured to propel the marine vessel in water; and

a shaft that extends along a length axis and pivotably couples the propulsion device to the deck;

wherein the propulsion device is pivotable into and between a stowed position and a deployed position, the propulsion device being closer to the deck in the stowed position than in the deployed position, and wherein the propulsor is rotatable about the length axis of the shaft when pivoting into and between the stowed position and the deployed position.

11. The marine vessel according to claim 10 , further comprising two or more pontoons coupled to the deck, whereby the two or more pontoons provide floatation for the marine vessel, and whereby the propulsion device is positioned between two of the two or more pontoons when in the stowed position.

12. The marine vessel according to claim 10 , wherein pivoting the shaft causes the shaft to rotate.

13. The marine vessel according to claim 10 , wherein the stowable propulsion device further comprises an actuator that pivots the propulsion device into and between the stowed position and the deployed position.

14. The marine vessel according to claim 13 , wherein the actuator is positioned below the deck.

15. The marine vessel according to claim 13 , wherein retracting the actuator pivots the propulsion device towards the deployed position.

16. The marine vessel according to claim 13 , wherein the shaft is caused to rotate about the length axis by pivoting the shaft into and between the stowed position and the deployed position.

17. The marine vessel according to claim 10 , wherein the shaft pivots 90 degrees and rotates 90 degrees between the stowed position and the deployed position.

18. The marine vessel according to claim 10 , wherein the propulsor remains below the deck in the stowed position.

19. The marine vessel according to claim 10 , wherein the propulsor is configured to propel the marine vessel in the water in a port-starboard direction when in the deployed position.

20. A stowable propulsion system for a marine vessel, the stowable propulsion system comprising:

a base configured to be coupled to the marine vessel;

a propulsion device configured to propel the marine vessel in water;

a shaft that extends along a length axis and pivotably couples the propulsion device to the base; and

an actuator operable to pivot the propulsion device relative to the base and to concurrently rotate the shaft about the length axis while pivoting the propulsion device into and between a stowed position and a deployed position, wherein the shaft is configured such rotating the shaft pivots the shaft.
