Techniques for providing instructions to an operator of a sea vessel via a computing device are described. The computing device can request, from another computing device, instructions regarding one or more of an intended course and action plan for the sea vessel, which can include at least one navigational instruction and/or deployment instruction. The computing device can send data to a display device to cause a prompt to be displayed. The prompt can include options regarding the at least one instruction. The computing device can send state information of the sea vessel to the other computing device. The state information can include the received input and location information of the sea vessel. Additionally, data can be received by the computing device from a shore based operator and data can be sent to one or more clients on shore.

A server provides necessary data including at least map data and weather data for an ocean area to be navigated by a boat, and its AR-display data generating unit AR-displays a destination of the boat on captured forward-looking images displayed on a display of an information communication terminal at every via-target-point en route. And a server navigation data learning unit sequentially receives navigation data of the outboard motor from the terminal and learns navigation data that enables to reduce fuel consumption rate of an engine mounted on the outboard motor, and a server operation assist unit transmits the learned navigation data to the terminal so as to assist the operator's operation of the outboard motor accordingly.

A ship having improved power efficiency is provided. The ship comprises: a power grid; a power cost generator which determines the cost of power; a generator which is connected to the power grid and analyzes the cost of power so as to autonomously determine whether to produce power; an energy storage device which is connected to the power grid and analyzes the cost of power so as to autonomously determine whether to store power; and a load which is connected to the power grid and analyzes the cost of power so as to autonomously determine whether to use power.

A system for flushing a cooling water pathway of a marine propulsion device with water supplied from a water source includes a water control device and a controller. The water control device is connected to the water source and the cooling water pathway of the marine propulsion device. The controller controls and causes the water control device to supply the water from the water source to the cooling water pathway so as to perform the flushing. The controller obtains propulsion device data including at least one of a pressure of the water, a flow rate of the water and a concentration of salt contained in the water in the cooling water pathway. The controller determines whether or not to stop a supply of the water by the water control device based on the propulsion device data.

A vessel hull stabilization system includes a housing having a rotatable shaft mounted thereto, the shaft configured to connect to a fin such that the fin is located on an outside of the vessel hull and the housing is located on an inside of the vessel hull. A drive system is mounted to the housing and includes a motor and a drive element. The motor is connected to a central shaft of the drive element and an outer element of the drive element is connected to the fin shaft. The drive element includes a plurality of teeth positioned between the outer element and the central shaft such that when the motor rotates the central shaft, the plurality of teeth oscillate in a direction perpendicular to an axis of the central shaft to interact with and rotate the outer element. A controller receives sensor readings to determine control signals to send to the motor(s) to impart rotation of the fin.

A method for calibrating a marine propulsion system that controls operation of a marine propulsion device on a marine vessel includes accepting an input signal from a user input device and determining an output signal corresponding to the input signal based on one or more stored parameters. The stored parameters are pre-calibrated to result in a predefined maneuver of the marine vessel. The marine propulsion device is operated according to the output signal and it is determined if any un-commanded maneuvers of the marine vessel result while operating the marine propulsion device according to the output signal. The method includes adapting one or more of the stored parameters so as to adjust operation of the marine propulsion device to abate the un-commanded vessel maneuvers. The one or more adapted parameters are saved and are used to determine subsequent output signals corresponding to subsequent input signals from the user input device.

A computer-implemented method of tracking vessel movement which comprises receiving a first vessel data message comprising a first vessel identifier, the first vessel data message having been transmitted at a first time and being associated with a first position; and receiving a second vessel data message comprising a second vessel identifier, the second vessel data message having been transmitted at a second time and being associated with a second position. The method also comprises determining if the first vessel identifier and the second vessel identifier are related. If the first vessel identifier and the second vessel identifier are related, a speed required for a vessel to have moved from the first position to the second position is determined; which is then determined if the speed is below a speed threshold; and if the speed is below the speed threshold, the first position is associated with the second position.

A system for detecting threats using an overt threat detector, the system includes a computer-readable memory configured to store computer executable instructions; a processor configured to execute the computer executable instructions, the computer executable instructions comprising receiving historical data regarding vessel patterns in a geographic area; generating, using a computer processor, at least one overt threat model based on the received historical data; receiving tracking data of vessels currently in the geographic area; analyzing, using the computer processor, the tracking data of vessels using the at least one overt threat model; and modifying, using the computer processor, the tracking data of vessels based on the results of the analyzing step; and an output device configured to output the modified tracking data of vessels is disclosed.
