Abstract

A hull assembly for a pontoon boat includes a hull extending in a longitudinal direction between a front end and a rear end. A first thruster assembly is attached to a first lateral side of the hull. A second thruster assembly is attached to a second lateral side of the hull. The first and second thruster assemblies include respective thrust units that are each movable between a deployed position and a stowed position.

First claim

What is claimed is:

1. A hull assembly for a pontoon boat, the hull assembly comprising:
a hull comprising a tubular main body and extending in a longitudinal direction between a front end and a rear end and configured for coupling to an underside of the pontoon boat;
a first thruster assembly attached to a first lateral side of the hull; and
a second thruster assembly attached to a second lateral side of the hull;
wherein the first and second thruster assemblies include respective thrust units that are each movable between a deployed position and a stowed position.

2. The hull assembly of claim 1 , further comprising a power source located within an interior of the hull, and first and second electrical connectors respectively connecting the first and second thruster assemblies to the power source.

3. The hull assembly of claim 2 , further comprising a controller located within the interior of the hull and electrically coupled to the power source and to the first and second thruster assemblies, the controller being configured to control at least one of:
(a) movement of the thrust units between the deployed and stowed positions; and
(b) speed and direction of propulsors of the thrust units.

4. The hull assembly of claim 3 , wherein the controller is configured to be communicatively coupled with a user input device on the pontoon boat, and wherein the user input device is configured to input commands to the controller to control the at least one of:
(a) movement of the thrust units between the deployed and stowed positions; and
(b) speed and direction of the propulsors of the thrust units.

5. The hull assembly of claim 2 , wherein the first and second electrical connectors extend through the respective first and second lateral sides of the hull in a watertight manner.

6. The hull assembly of claim 1 , wherein each of the first and second thruster assemblies further comprises a shaft attached to the thrust unit, a joint coupling the shaft to the hull in a movable manner, and an actuator configured to move the shaft with respect to the hull via the joint so as to move the thrust unit between the deployed and stowed positions.

7. The hull assembly of claim 6 , wherein each joint is configured to pivot its respective shaft and thrust unit such that in the stowed position the thrust units are located closer to one another in the longitudinal direction than in the deployed position, and such that in the deployed position the thrust units are located further from one another in the longitudinal direction than in the stowed position.

8. The hull assembly of claim 1 , further comprising a bracket configured to connect the hull to the underside of the pontoon boat.

9. The hull assembly of claim 1 , wherein the thrust units are located below a bottom surface of the hull when the thrust units are in the deployed position, and the thrust units are located alongside the respective first and second lateral sides of the hull when the thrust units are in the stowed position.

10. The hull assembly of claim 1 , wherein the first thruster assembly is attached to the first lateral side of the hull closer to the front end of the hull than to the rear end of the hull, and the second thruster assembly is attached to the second lateral side of the hull closer to the rear end of the hull than to the front end of the hull.

11. The hull assembly of claim 1 , wherein the first lateral side of the hull is opposite the second lateral side of the hull.

12. A hull assembly for a pontoon boat, the hull assembly comprising:
a hull comprising a tubular main body and extending in a longitudinal direction between a front end and a rear end and configured to be coupled to an underside of the pontoon boat; and
a first thruster assembly attached to a first lateral side of the hull closer to the front end of the hull than to the rear end of the hull, the first thruster assembly including a first shaft, a first joint coupling the first shaft to the hull in a movable manner, a first thrust unit attached to the first shaft, and a first actuator configured to move the first shaft and the first thrust unit with respect to the hull via the first joint;
wherein the first actuator is configured to move the first shaft and the first thrust unit between a stowed position, in which the first thrust unit is located alongside the first lateral side of the hull, and a deployed position, in which the first thrust unit is located below a bottom surface of the hull.

13. The hull assembly of claim 12 , further comprising a second thruster assembly attached to a second lateral side of the hull, the second thruster assembly including a second shaft, a second joint coupling the second shaft to the hull in a movable manner, a second thrust unit attached to the second shaft, and a second actuator configured to move the second shaft and the second thrust unit with respect to the hull via the second joint;
wherein the second actuator is configured to move the second shaft and the second thrust unit between a stowed position, in which the second thrust unit is located alongside the second lateral side of the hull, and a deployed position, in which the second thrust unit is located below the bottom surface of the hull.

14. The hull assembly of claim 13 , wherein the second thruster assembly is attached to the second lateral side of the hull closer to the rear end of the hull than to the front end of the hull.

15. The hull assembly of claim 13 , wherein the first and second joints are configured to pivot the respective first and second shafts and thrust units such that in the stowed position the first and second thrust units are located closer to one another in the longitudinal direction than in the deployed position, and in the deployed position the first and second thrust units are located further from one another in the longitudinal direction than in the stowed position.

16. The hull assembly of claim 13 , further comprising a power source located within an interior of the hull, and first and second electrical connectors respectively connecting the first and second thruster assemblies to the power source.

17. The hull assembly of claim 16 , further comprising a controller located within the interior of the hull and electrically coupled to the power source and to the first and second thruster assemblies, the controller being configured to control at least one of:
(a) movement of the first and second thrust units between the deployed and stowed positions; and
(b) speed and direction of propulsors of the first and second thrust units.

18. The hull assembly of claim 17 , wherein the controller is configured to be communicatively coupled with a user input device on the pontoon boat, and wherein the user input device is configured to input commands to the controller to control the at least one of:
(a) movement of the first and second thrust units between the deployed and stowed positions; and
(b) speed and direction of the propulsors of the first and second thrust units.

19. The hull assembly of claim 16 , wherein the first and second electrical connectors extend through the first and second lateral sides of the hull, respectively, in a watertight manner.

20. The hull assembly of claim 12 , further comprising a bracket configured to connect the hull to the underside of the pontoon boat.
