Description

TECHNICAL FIELD

This disclosure relates to implementations of a boat propulsion and guidance system.

BACKGROUND

Boats are small to medium sized sailing vessels of various types, shapes, etc. For example, FIG. 7 illustrates an example existing boat such as a typical offshore fishing boat. Boats often include a motorized configuration for propelling and/or maneuvering the boat. For example, some boats usually include an outboard motor for propelling and one or more thruster motors for maneuvering or steering. Other boats usually include one or more main engines for propelling and maneuvering, which are usually capable of high speeds, and may also include one or more thruster devices for more controllable maneuvering, such as at lower speeds.

However, the motors are usually mounted outside the body or hull of the boat and are too noisy to operate while trying to fish or otherwise be quiet while boating. Also, the motors are usually separate devices that have to be separately operated or controlled. Furthermore, the existing configurations include sharp turns or radii that make the configurations inefficient. Additionally, the existing configurations are prone to fouling up or bio-fouling when not in use from the growth of biological material such as algae, weeds, etc. on the exposed motors and other components.

Moreover, existing thruster designs are mounted inside the hull of the boat (inboard) or outside the hull (outboard). Inboard thruster designs are used to force a section of the boat in a particular direction for steering or maneuvering purposes. Some previous designs have exterior nozzles to vector the force. The nozzles and other designs have many sharp turns or radii that hinder their efficiency. Outboard designs usually have articulated directional control and have to be stowed during high speed operation or placed in a position that will not encounter turbulence.

DETAILED DESCRIPTION

Implementations of a boat propulsion and guidance system are provided. In some implementations, the boat propulsion and guidance system comprises one or more conduits and propulsion devices. In some implementations, the boat propulsion and guidance system may further comprise one or more valve devices. In some implementations, the boat propulsion and guidance system may further comprise a controller.

In some implementations, the boat propulsion and guidance system is configured to steer, maneuver, and/or otherwise propel a boat.

In some implementations, the boat propulsion and guidance system is configured to steer, maneuver, and/or otherwise propel a boat as a single, combined, and/or integrated system of components that can be singly or commonly operated and/or controlled.

In some implementations, the boat propulsion and guidance system is configured to position on a boat and operate quietly to the surrounding environment of the boat such that the boat propulsion and guidance system can be used while fishing or otherwise boating while needing to be quiet.

In some implementations, the boat propulsion and guidance system is configured to be more efficient by providing a generally straight flow of propulsion without sharp turns or radii, such as by comprising generally straight conduit.

In some implementations, the boat propulsion and guidance system is configured to close up when not in use to prevent the undesirable growth of biological material or bio-fouling on components of the boat propulsion and guidance system, such as by algae, weeds, etc.

In some implementations, the boat propulsion and guidance system is configured to move (e.g., steer, maneuver, and/or otherwise propel) a boat in one or more directions, such as forward, backward, leftward, rightward, and/or sideways. In some implementations, the boat propulsion and guidance system may be configured to move a boat in a 360-degree zero turn radius motion.

In some implementations, the boat propulsion and guidance system may be configured to position a boat by dynamic anchoring to cause the boat to remain in a desired position in the water.

In some implementations, the boat propulsion and guidance system may be configured to be installed and/or used as a primary and/or sole propulsion and guidance system of a boat. In some implementations, the boat propulsion and guidance system may be configured to be installed and/or used in addition to another propulsion device of a boat.

In some implementations, the boat propulsion and guidance system is configured to be used on any suitable configuration of boat, such as a single hull boat or a multiple hull boat, such as a catamaran, trimaran, etc.

In some implementations, the boat propulsion and guidance system may be configured to receive global positioning system (GPS) coordinate inputs for controlling the operation of the boat propulsion and guidance system.

In some implementations, the boat propulsion and guidance system may be configured to receive magnetometer and/or accelerometer inputs for controlling the operation of the boat propulsion and guidance system.

In some implementations, the boat propulsion and guidance system may be configured to execute proportional, integral, derivative software for controlling the operation of the boat propulsion and guidance system.

In some implementations, the boat propulsion and guidance system may be configured to use analog controls to produce force in any direction by using varying amounts of propulsion in any of four or more directions.

In some implementations, a method of using the boat propulsion and guidance system comprises installing the boat propulsion and guidance system to a boat and operating the boat propulsion and guidance system to move (e.g., steer, maneuver, and/or otherwise propel) the boat in one or more directions. In some implementations, the method may further comprise operating the boat propulsion and guidance system to dynamically anchor the boat to remain in a desired position in the water.

Boats are small to medium sized sailing vessels of various types, shapes, etc. For example, FIG. 7 illustrates an example existing boat 10 such as a typical offshore fishing boat. Boats 10 often include a motorized configuration for propelling and/or maneuvering the boat. For example, as shown in FIG. 7, some boats 10 usually include an outboard motor for propelling and one or more thruster motors for maneuvering or steering. Other boats usually include one or more main engines for propelling and maneuvering, which are usually capable of high speeds, and may also include one or more thruster devices for more controllable maneuvering, such as at lower speeds.

As shown in FIG. 7, the motors are usually mounted outside the body or hull of the boat 10 and are too noisy to operate while trying to fish or otherwise be quiet while boating. Also, the motors are usually separate devices that have to be separately operated or controlled. As also shown in FIG. 7, the sides or portions of a boat 10 are known as the bow or front, the stern or rear, the port or left side, and the starboard or right side.

The existing configurations for propelling and/or maneuvering a boat 10 include sharp turns or radii that make the configurations inefficient. Additionally, the existing configurations are prone to fouling up or bio-fouling when not in use from the growth of biological material such as algae, weeds, etc. on the exposed motors and other components.

Moreover, existing thruster designs are mounted inside the hull of the boat (inboard) or outside the hull (outboard). Inboard thruster designs are used to force a section of the boat in a particular direction for steering or maneuvering purposes. Some previous designs have exterior nozzles to vector the force. The nozzles and other designs have many sharp turns or radii that hinder their efficiency. Outboard designs usually have articulated directional control and have to be stowed during high speed operation or placed in a position that will not encounter turbulence.

The boat 10 of FIG. 7 is an example of any suitable boat for which the boat propulsion and guidance system 100 can be used, as described below.

FIGS. 1, 2, 3, 4, 5, 6A-6C, and 8 illustrate implementations of a boat propulsion and guidance system according to the present disclosure.

With respect to the above described features of the boat propulsion and guidance system 100, FIGS. 6A-6C illustrate an implementation of a boat propulsion and guidance system 100 (100A) according to the present disclosure. As shown in FIG. 6A, in some implementations, the boat propulsion and guidance system 100 comprises a pump 122 with an attached motor 121, a right and a left intake port 111a, a right and a left exhaust port 111b, two differential valves 134, and an actuator 135 that controls the differential valves 134. In some implementations, the boat propulsion and guidance system 100 further comprises one or more conduits 110 and/or controllers 140.

As shown in FIG. 6A, in some implementations, the right and the left water intake ports 111a are mounted at or about −45 degrees and +45 degrees respectively from the forward lengthwise extending center line of the boat propulsion and guidance system 100 and/or the boat.

As shown in FIGS. 6A and 6C, in some implementations, the differential valves 134 are configured to allow the flow of propulsion through the right (or starboard side) intake port 111a and the left (or port side) exhaust port 111b when the actuator 135 is extended, retracted, or otherwise suitably activated. In some implementations, the differential valves 134 are configured to prevent the flow of propulsion through the left intake port 111a and the right exhaust port 111b when the actuator 135 is extended, retracted, or otherwise suitably activated.

In some implementations, the boat propulsion and guidance system 100 is thereby configured to allow propulsion, such as water, air, etc. propelled by the pump 122 and the motor 121, to flow from the right intake port 111a to the left exhaust port 111b when the actuator 135 is extended, retracted, or otherwise suitably activated. In some implementations, the boat propulsion and guidance system 100 is thereby configured to allow a cross-flow of the propulsion that produces a forward and lateral (e.g., rightward) movement of a boat.

In some implementations, the boat propulsion and guidance system 100 is configured to operate by the controller 140 receiving global positioning system (GPS) coordinate inputs. In some implementations, the GPS coordinate inputs may be based on a desired location or destination.

In some implementations, the boat propulsion and guidance system 100 is configured to operate by the controller 140 controlling the actuator 135 to control propulsion flow through the ports 111a, 111b by controlling the differential valves 134. In some implementations, the boat propulsion and guidance system 100 is thereby configured to steer a boat.

In some implementations, the boat propulsion and guidance system 100 is configured to operate by the controller 140 controlling the motor 121 to control propulsion flow through the ports 111a, 111b by controlling the pump 122. In some implementations, the boat propulsion and guidance system 100 is thereby configured to control the speed of a boat.

In some implementations, the boat propulsion and guidance system 100 is configured to control the speed of the boat based on the distance to the desired location. For example, in some implementations, the boat propulsion and guidance system 100 is configured to control the speed of the boat such that the shorter the distance to the desired location, the lower the speed of the boat.

In some implementations, the boat propulsion and guidance system 100 may be configured to operate to control a boat in any other suitable way.

With respect to the above described features of the boat propulsion and guidance system 100, FIG. 1 illustrates another implementation of a boat propulsion and guidance system 100 (100B) according to the present disclosure. As shown in FIG. 1, in some implementations, the boat propulsion and guidance system 100 comprises a first conduit 110c having a first port 111c1 and a second port 111c2 and a second conduit 110d having a first port 111d1 and a second port 111d2.

In some implementations, the boat propulsion and guidance system 100 comprises first conduit valves 131c1, 131c2 and second conduit valves 131d1, 131d2. In some implementations, the boat propulsion and guidance system 100 comprises first conduit thruster devices 120c1, 120c2 and second conduit thruster devices 120d1, 120d2. In some implementations, the boat propulsion and guidance system 100 further comprises one or more controllers 140.

As shown in FIG. 1, in some implementations, the first ports 111c1, 111d1 are mounted arranged in an outward angle (e.g., of or about −45 degrees and +45 degrees) respectively on opposite sides of the forward lengthwise extending center line of the boat propulsion and guidance system 100 and/or the boat. Similarly, in some implementations, the second ports 111c2, 111d2 are mounted arranged in an outward angle (e.g., of or about −45 degrees and +45 degrees) respectively on opposite sides of the rearward lengthwise extending center line of the boat propulsion and guidance system 100 and/or the boat.

As shown in FIG. 1, in some implementations, the ports 111c1, 111d1, 111c2, 111d2 are mounted as described such that the first and second conduits 110c, 110d extend diagonally between the first ports 111c1, 111d1 and the second ports 111c2, 111d2 respectively, such as in an X-shaped or cross configuration. For example, in some implementations, the first conduit 110c extends from the first port 111c1 at the front (bow) left (port) to the second port 111c2 at the back (stern) right (starboard) and the second conduit 110d extends from the first port 111d1 at the front right to the second port 111d2 at the back left when the boat propulsion and guidance system 100 is used on a boat.

In some implementations, the ports 111c1, 111d1, 111c2, 111d2 may be positioned in any other suitable configuration.

In some implementations, the conduits 110c, 110d may be connected together. For example, in some implementations, the conduits 110c, 110d may be attached together where the conduits 110c, 110d cross in the cross configuration, such as at or near the lengthwise center of the conduits 110c, 110d.

In some implementations, the conduits 110c, 110d may be attached together but not inter-connected or cross-connected to allow the flow of propulsion between the conduits 110c, 110d.

As shown in FIG. 1, in some implementations, the conduits 110c, 110d may be connected together such that the conduits 110c, 110d are inter-connected or cross-connected. For example, in some implementations, the conduits 110c, 110d may be connected such that propulsion can flow between the conduits 110c, 110d.

In some implementations, the conduits 110c, 110d may be cross-connected such that propulsion can flow from a port 111c1, 111c2 of the first conduit 110c to a port 111d1, 111d2 of the second conduit 110d. In some implementations, the conduits 110c, 110d may be cross-connected such that propulsion can flow from a port 111d1, 111d2 of the second conduit 110d to a port 111c1, 111c2 of the first conduit 110c.

In some implementations, the conduits 110c, 110d may be cross-connected such that propulsion can flow between the conduits 110c, 110d in any other suitable way.

In some implementations, the conduits 110c, 110d may be connected or attached together in any other suitable configuration.

In some implementations, the boat propulsion and guidance system 100 may alternately comprise a multi-section, multi-port conduit (e.g., similar to the boat propulsion and guidance system 100C described below for FIG. 2) having the above described features and configuration of the conduits 110c, 110d.

As shown in FIG. 1, in some implementations, the first conduit valves 131c1, 131c2 are positioned at or adjacent to the first conduit ports 111c1, 111c2 respectively. In some implementations, the second conduit valves 131d1, 131d2 are positioned at or adjacent to the second conduit ports 111d1, 111d2 respectively. For example, in some implementations, the valves 131c1, 131c2, 131d1, 131d2 may be positioned immediately inside the ports 111c1, 111c2, 111d1, 111d2 respectively.

In some implementations, the valves 131c1, 131c2, 131d1, 131d2 may be positioned in any other suitable location to control the flow of propulsion through the ports 111c1, 111c2, 111d1, 111d2 and/or the conduits 110c, 110d respectively.

In some implementations, the first conduit thruster devices 120c1, 120c2 may be in any suitable position of the first conduit 110c adjacent to the first conduit ports 111c1, 111c2 respectively. In some implementations, the second conduit thruster devices 120d1, 120d2 may be in any suitable position of the second conduit 110d adjacent to the second conduit ports 111d1, 111d2 respectively.

For example, as shown in FIG. 1, in some implementations, the thruster devices 120c1, 120c2, 120d1, 120d2 may be positioned adjacent to the valves 131c1, 131c2, 131d1, 131d2 respectively opposite the ports 111c1, 111c2, 111d1, 111d2. In some implementations, the thruster devices 120c1, 120c2, 120d1, 120d2 can thereby be enclosed in the conduits 110c, 110d when the valves 131c1, 131c2, 131d1, 131d2 are closed, such as to prevent exposure and biological fouling when the boat propulsion and guidance system 100 is not in operation.

In some implementations, the thruster devices 120c1, 120c2, 120d1, 120d2 are further positioned such that the thruster devices 120c1, 120c2, 120d1, 120d2 can control the direction and/or speed of propulsion, such as moving water, through the conduits 110c, 110d and ports 111c1, 111c2, 111d1, 111d2.

In some implementations, the boat propulsion and guidance system 100 is configured to use the force of water displacement and/or the force of pressure against the outside water to produce motion of a boat in a desired direction. For example, in some implementations, the boat propulsion and guidance system 100 is configured to propel water flow from the left front port 111c1 to the right rear port 111c2 to produce a forward and left (port) motion of the boat. In some implementations, the boat propulsion and guidance system 100 is configured to propel water flow from the right front port 111d1 to the left rear port 111d2 to produce a forward and right (starboard) motion of the boat.

In some implementations, the boat propulsion and guidance system 100 is configured to propel water flow from both left ports 111c1, 111d2 to both right ports 111d1, 111c2 to produce a leftward sideways motion of the boat. In some implementations, the boat propulsion and guidance system 100 is configured to propel water flow from both right ports 111d1, 111c2 to both left ports 111c1, 111d2 to produce a rightward sideways motion of the boat.

In some implementations, the boat propulsion and guidance system 100 is configured to propel water flow from both front ports 111c1, 111d1 to both rear ports 111c2, 111d2 to produce a forward motion of the boat. In some implementations, the boat propulsion and guidance system 100 is configured to propel water flow from both rear ports 111c2, 111d2 to both front ports 111c1, 111d1 to produce a reverse motion of the boat.

In some implementations, the boat propulsion and guidance system 100 is configured to use the controller 140 comprising analog motor controls with a central controller to produce force in any desired direction. In some implementations, the force can provide motion in any suitable direction. In some implementations, the force can provide dynamic anchoring that causes a boat to remain in a desired position while compensating for outside forces.

In some implementations, the boat propulsion and guidance system 100 is configured to control the thruster devices 120c1, 120c2, 120d1, 120d2 by a magnetometer and/or accelerometer input or by global positioning system (GPS) signals. In some implementations, the boat propulsion and guidance system 100 is configured to use proportional, integral, derivative software to smooth out the input signals to produce a steady, accurate movement of a boat.

In some implementations, the boat propulsion and guidance system 100 is configured to operate more efficiently by providing a generally straight flow of propulsion without sharp turns or radii.

In some implementations, the boat propulsion and guidance system 100 is configured to close the valves 131c1, 131c2, 131d1, 131d2 when not in use to prevent the growth of biologic material or bio-fouling, such as to the thruster devices 120c1, 120c2, 120d1, 120d2 and/or other components of the boat propulsion and guidance system 100.

With respect to the above described features of the boat propulsion and guidance system 100, FIG. 2 illustrates another implementation of a boat propulsion and guidance system 100 (100C) according to the present disclosure. As shown in FIG. 2, in some implementations, the boat propulsion and guidance system 100 comprises a multi-section, multi-port conduit 110e having sections 110e1, 110e2, 110e3, 110e4, 110e5 and ports 111e1, 111e2, 111e3, 111e4.

In some implementations, the boat propulsion and guidance system 100 comprises valves 131e1, 131e2, 131e3, 131e4 and a thruster device 120e. In some implementations, the boat propulsion and guidance system 100 further comprises one or more controllers 140.

As shown in FIG. 2, in some implementations, the ports 111e1, 111e2 are positioned arranged in an outward angle (e.g., of or about −45 degrees and +45 degrees) respectively on opposite sides of the forward lengthwise extending center line of the boat propulsion and guidance system 100 and/or the boat. Similarly, in some implementations, the ports 111e3, 111e4 are positioned arranged in an outward angle (e.g., of or about −45 degrees and +45 degrees) respectively on opposite sides of the rearward lengthwise extending center line of the boat propulsion and guidance system 100 and/or the boat.

As shown in FIG. 2, in some implementations, the ports 111e1, 111e2, 111e3, 111e4 are positioned as described such that the conduit sections 110e1, 110e2, 110e3, 110e4 extend diagonally from the conduit section 110e5 to the ports 111e1, 111e2, 111e3, 111e4 respectively, such as in a generally X-shaped or cross configuration.

For example, in some implementations, the sections 110e1, 110e2 extend respectively from a first inter-connection to the section 110e5 to the ports 111e1, 111e2, such as in a Y-shaped configuration. Similarly, in some implementations, the sections 110e3, 110e4 extend respectively from a second inter-connection to the section 110e5 (opposite the first inter-connection) to the ports 111e3, 111e4, such as in an inverted Y-shaped configuration.

In some implementations, the ports 111e1, 111e2, 111e3, 111e4 may be positioned in any other suitable configuration.

As shown in FIG. 2, in some implementations, the conduit sections 110e1, 110e2, 110e3, 110e4, 110e5 are inter-connected or cross-connected such that propulsion can flow between the sections 110e1, 110e2, 110e3, 110e4, 110e5 from the ports 111e1, 111e2, 111e3, 111e4 in any suitable configuration, such as described below. In some implementations, the sections 110e1, 110e2, 110e3, 110e4, 110e5 may be connected or attached together in any other suitable configuration.

In some implementations, the boat propulsion and guidance system 100 may alternately comprise a plurality of inter-connected conduits (e.g., similar to the boat propulsion and guidance system 100B described above for FIG. 1) having the same or similar above described features and configuration of the multi-section, multi-port conduit 110e.

In some implementations, the valves 131e1, 131e2, 131e3, 131e4 may be positioned in any other suitable location to control the flow of propulsion through the ports 111e1, 111e2, 111e3, 111e4 and/or the conduit 110e1, 110e2, 110e3, 110e4 respectively.

In some implementations, the valves 131e1, 131e2, 131e3, 131e4 may comprise a rod or handle that can produce a partial or complete cutoff of the flow of propulsion of the boat propulsion and guidance system 100. In some implementations, the valves 131e1, 131e2, 131e3, 131e4 may be configured to produce a partial or complete cutoff of the flow of propulsion with less than 360 degrees of motion.

In some implementations, the valves 131e1, 131e2, 131e3, 131e4 may be configured to produce a partial or complete cutoff of the flow of propulsion of the boat propulsion and guidance system 100 in any other suitable way.

In some implementations, the thruster device 120e is positioned in the center conduit section 110e5 between the inter-connections of the outer conduit sections 110e1, 110e2, 110e3, 110e4. In some implementations, the thruster device 120e may be positioned in any suitable location of the section 110e5.

In some implementations, the boat propulsion and guidance system 100 is configured to operate the thruster device 120e to produce forward or reverse direction motion of the boat.

In some implementations, the boat propulsion and guidance system 100 is thereby configured to produce a forward leftward or rightward motion of a boat. In some implementations, the boat propulsion and guidance system 100 is also thereby configured to produce a reverse leftward or rightward motion of the boat.

In some implementations, the boat propulsion and guidance system 100 is configured to manipulate or otherwise control the valves 131e1, 131e2, 131e3, 131e4 and the thruster device 120e with analog controls of the controller 140 to produce the motion of a boat.

In some implementations, the boat propulsion and guidance system 100 is configured to control the valves 131e1, 131e2, 131e3, 131e4 and the thruster device 120e by a magnetometer and/or accelerometer input or by global positioning system (GPS) signals. In some implementations, the boat propulsion and guidance system 100 is configured to use proportional, integral, derivative software to smooth out the input signals to produce a steady, accurate movement of a boat.

In some implementations, the boat propulsion and guidance system 100 is configured to very efficiently maintain a desired course or dynamic anchoring of a boat.

In some implementations, the boat propulsion and guidance system 100 is configured to operate more efficiently by providing a generally straight flow of propulsion without sharp turns or radii.

In some implementations, the boat propulsion and guidance system 100 is configured to close the valves 131e1, 131e2, 131e3, 131e4 when not in use to prevent the growth of biologic material or bio-fouling, such as to the thruster device 120e and/or other components of the boat propulsion and guidance system 100.

In some implementations, the boat propulsion and guidance system 100 can produce motion of a boat in a desired direction generally the same or similar to as described above for the boat propulsion and guidance system 100B of FIG. 1. For example, in some implementations, the boat propulsion and guidance system 100 may tradeoff some of the motion capability, such as sideways motion, for added efficiency, such as lower weight, simpler design, etc., by having one (or two) thruster device(s) instead of two (or four).

In some implementations, the boat propulsion and guidance system 100 may comprise any other suitable features that are the same or similar to as described above for the boat propulsion and guidance system 100B of FIG. 1.
