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 bilge pump monitoring system for a bilge pump on a marine vessel includes a current sensor configured to measure a current draw of the bilge pump, and a bilge pump monitor module executable on a processor. The bilge pump monitor module is configured to receive current draw measurements by the current sensor and determine a pump diagnosis of the bilge pump based on the current draw measurements. The pump diagnosis is then wirelessly communicated to a user located remotely from the marine vessel.

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.

The present invention relates to a method for controlling the fuel consumption of a ship, the ship comprising an engine and a controllable pitch propeller, wherein torque and engine speed are adjusted to correspond to an output set point value. The adjustment is such that the engine is operated in an operating condition with an engine speed and a propeller pitch of the controllable pitch propeller such that the fuel consumption of the ship is brought and/or held within a desired fuel consumption range.

A method for controlling marine vessel speed includes determining a setpoint vessel speed, which is constant while the system is operating in a cruise control mode. The method includes using vessel speed feedback control to adjust operational characteristics of the engine so as to achieve the setpoint vessel speed. The method also includes determining a measured vessel speed and filtering the measured vessel speed. In response to determining that the measured vessel speed is within a given range of the constant setpoint vessel speed, the method includes transitioning to the cruise control mode and comparing the filtered measured vessel speed to the constant setpoint vessel speed for purposes of the feedback control.

An electrical distribution system for personal water craft. The primary components include a digital switching device; a series of power lines; and one or more remote controls, a control panel, or both. The digital switching device is preferably a bank of solid state relay switches controlled by an MCU. The control panel also has an MCU. The control panel MCU communicates with the digital switching device MCU. This allows signals from the control panel to travel on a single communication cable to the digital switching device, significantly reducing the control panel footprint compared to prior art control panels. When a radio frequency (RF) receiver is provided, the electrical distribution system may receive signals from a remote control. The remote control may be utilized in addition to or in lieu of the control panel. Power lines run from the digital switching device to wherever power is desired in the vessel.
