A navigational system for guiding a boat onto a trailer comprising at least a portion of a tow vehicle which forms a natural marker for the navigation system. A camera is located on the boat to assist the navigational system with aligning a longitudinal axis of the boat with a longitudinal axis of the trailer. A central vertical (mid) axis of the camera is aligned with the longitudinal axis of the boat. An image processing unit receives and processes images from the camera. The image processing unit, based upon a determination of a position of the central vertical (mid) axis of the camera relative to a target area of the detected natural marker, generating guidance commands to assist a user with alignment of the longitudinal axis of the boat with the longitudinal axis of the trailer and thereby facilitate proper loading of the boat onto the trailer.

A method of moving liquid manure in a liquid manure lagoon involves: driving an amphibious vehicle into the liquid manure lagoon by remotely controlling speed and direction of the amphibious vehicle on the ground, the amphibious vehicle having a ground-engaging propulsion structure for driving the amphibious vehicle on the ground and a floatable vehicle body to float the amphibious vehicle in the liquid manure lagoon; and, moving the liquid manure in the liquid manure lagoon by remotely controlling speed and direction of the amphibious vehicle in the liquid manure lagoon.

A self-propelling watercraft system is provided. The watercraft has a base with a plurality of sidewalls extending from the base to form a cockpit. The base also has a recess, where a pump can detachably connect to the hull within the recess. The pump has an intake valve on a first end and a nozzle on a second end that is opposite the first end. The intake valve can intake water. The nozzle can jettison water received in the pump from the intake valve and agitate water surrounding the nozzle.

Control system for controlling operations of a marine vessel having a first engine and a second engine is provided. Parity switches are operable to start/stop first and second engine. Each parity switch is actuated for first time to activate remote start/stop control of respective engine. Each switch is actuated for second time to switch respective engine to ON or OFF state. Operator console is communicatively coupled to parity switches to receive first and/or second user inputs. Propulsion control unit is communicably coupled to operator console via network communication channel, first engine control unit of first engine and second engine control unit of second engine. Propulsion control unit receives operational parameters for engines from engine control units and receives first and second user inputs from operator console. Propulsion control unit transmits engine operating signals for operating respective engines in response to first and/or second user input and based on operational parameters.

The present disclosure provides a ship unloading control system, a ship loading control system and related systems and apparatuses, capable of achieving fully automated ship loading and unloading. The ship unloading control system includes: a scheduling center system configured to generate a ship unloading plan based on ship information and container information of a target ship and shore crane apparatus information, generate a ship berthing task and a ship unloading task based on the ship unloading plan, and transmit the ship berthing task and the ship unloading task to a ship control system of the target ship and a shore crane control system of a target shore crane apparatus, respectively; the ship control system configured to transmit the ship information and the container information to the scheduling center system, control the target ship to move to an operation area corresponding to the target shore crane apparatus in accordance with the received ship berthing task, and transmit a ship in-position notification message to the shore crane control system of the target shore crane apparatus; and the shore crane control system configured to control, upon receiving the ship in-position notification message from the ship control system, the target shore crane apparatus to load a container on the target ship onto a transportation vehicle in accordance with the ship unloading task.

An amphibious vehicle has a floatable vehicle body; ground engaging propulsion structure having a plurality of ground engaging elements powered by a hydraulic motor; a fluid pump for pumping liquid manure; a power source connected to a hydraulic pump and configured to provide power to both the ground engaging propulsion structure and the fluid pump; and, remote control structure for controlling the ground engaging propulsion structure and a flow of fluid from the fluid pump. The speed and/or direction of the vehicle is remotely controllable by an operator remote from the vehicle when the vehicle is ground engaging and when the vehicle is floating.

A trolling motor control system to control the operation of a trolling motor including a rotatable propulsion support shaft to couple a propulsion unit to a boat including a plurality of modules and one or more control devices including a foot pedal control having a foot pedal pivotally mounted to the deck of the boat wherein the plurality of modules includes logic and circuitry to send and receive signals between the modules and to send and receive signals to and from the foot pedal control to synchronize or align the corresponding angular position of rotatable propulsion support shaft in the horizontal plane relative to the longitudinal axis of the boat with the angular position of the foot pedal control in the vertical plane relative to the deck of the boat and to generate tactile feedback to the pivotal foot pedal.

A modular steering console. The modular steering console has a main console portion having a top side and a side. The top side includes holes for receiving bolts. The side of the main console portion has holes for receiving bolts. The modular steering console has one or more brackets having slots in a top side configured to be fastened to the main console top side by bolts through the slots to allow lateral adjustment of the brackets while allowing a side of the brackets and the side of the main console portion to sandwich a side of a boat.

A system and method for guiding a boat onto a trailer, which comprises at least one marker mounted on the trailer; a camera located on the boat to assist the system with determining a longitudinal axis of the boat, and generating images of at least a front area of the boat and the at least one marker; an image processing unit for 1) receiving and processing the images to determine the at least one marker, 2) estimating the longitudinal axis of the trailer, 3) generating a desired boat trajectory for aligning the longitudinal axis of the boat with the longitudinal axis of the trailer; and 4) periodically generating guidance output commands to the user to assist the user with following the desired boat trajectory and facilitate loading of the boat on the trailer; and an image display for sequentially displaying the generated images of the camera to a user.
