Boat and boat maneuvering system

1. A boat comprising:

a boat body;

a propulsion unit that propels the boat body;

a steering wheel that turns about a first turning axis to change a propulsive direction of the propulsion unit; and

a paddle operator on the steering wheel and including a first paddle and a second paddle; wherein

at least one of the first paddle and the second paddle performs a throttle operation and a shift operation on the propulsion unit.

2. The boat according to claim 1 , wherein operation of the first paddle performs the throttle operation on the propulsion unit, and operation of the second paddle performs the shift operation on the propulsion unit.

3. The boat according to claim 1 , wherein the paddle operator is turned about the first turning axis together with the steering wheel, and pivots about a second turning axis which is located perpendicular or substantially perpendicular to the first turning axis to perform the throttle operation and the shift operation on the propulsion unit.

4. The boat according to claim 1 , wherein the paddle operator is located behind the steering wheel and extends along the steering wheel.

5. The boat according to claim 4 , wherein the paddle operator has an arcuate or substantially arcuate shape which extends along the steering wheel.

6. The boat according to claim 1 , wherein the first paddle moves in a direction toward the steering wheel to perform the throttle operation on the propulsion unit in a throttle opening direction, and moves in a direction away from the steering wheel to perform the throttle operation on the propulsion unit in a throttle closing direction.

7. The boat according to claim 1 , wherein the paddle operator is biased in a direction away from the steering wheel.

8. The boat according to claim 1 , wherein the steering wheel turns less than 180 degrees about the first turning axis.

9. The boat according to claim 1 , wherein the first paddle and the second paddle are bilaterally symmetrical with respect to each other on the steering wheel when the steering wheel is at a centered position.

10. The boat according to claim 1 , wherein the steering wheel is bilaterally symmetric and vertically asymmetric when the steering wheel is at a centered position.

11. The boat according to claim 1 , further comprising a detector that detects a position of the paddle operator; wherein

the throttle operation and the shift operation on the propulsion unit are performed in response to an electric signal based on the position detected by the detector.

12. The boat according to claim 1 , wherein

the first paddle performs the throttle operation in a forward movement direction and the shift operation in the forward movement direction; and

the second paddle performs the throttle operation in a reverse movement direction, the shift operation to a neutral position, the shift operation in the reverse movement direction, and a deceleration operation.

13. The boat according to claim 1 , wherein the propulsion unit includes a jet propulsion device, an outboard motor, an inboard motor, or an inboard-outboard motor.

14. The boat according to claim 13 , wherein the propulsion unit includes the jet propulsion device, and the boat further comprises:

an electric power steering actuator that generates an assist force that reduces a load applied to a user when the user turns the steering wheel.

15. The boat according to claim 1 , wherein the first paddle is located in a first direction with respect to the first turning axis, and the second paddle is located in a second direction with respect to the first turning axis.

16. A boat maneuvering system comprising:

a steering wheel that turns about a first turning axis to change a propulsive direction of a propulsion unit that propels a boat body; and

an paddle operator on the steering wheel and including a first paddle and a second paddle; wherein

at least one of the first paddle and the second paddle performs a throttle operation and a shift operation on the propulsion unit.

17. The boat maneuvering system according to claim 16 , wherein operation of the first paddle performs the throttle operation on the propulsion unit, and operation of the second paddle performs the shift operation on the propulsion unit.

18. The boat maneuvering system according to claim 16 , wherein the paddle operator is turned about the first turning axis together with the steering wheel and is pivoted about a second turning axis which is located perpendicular or substantially perpendicular to the first turning axis to perform the throttle operation and the shift operation on the propulsion unit.

19. The boat maneuvering system according to claim 16 , wherein the paddle operator is located behind the steering wheel and extends along the steering wheel.

20. The boat maneuvering system according to claim 16 , wherein the first paddle moves in a direction toward the steering wheel to perform the throttle operation on the propulsion unit in a throttle opening direction, and moves in a direction away from the steering wheel to perform the throttle operation on the propulsion unit in a throttle closing direction.

21. The boat maneuvering system according to claim 16 , wherein the steering wheel turns less than 180 degrees about the first turning axis.

22. The boat maneuvering system according to claim 16 , further comprising a detector that detects a position of the paddle operator; wherein

the throttle operation and the shift operation on the propulsion unit are performed in response to an electric signal based on the position detected by the detector.

23. The boat maneuvering system according to claim 16 , wherein the first paddle is located in a first direction with respect to the first turning axis, and the second paddle is located in a second direction with respect to the first turning axis.
