Abstract:
Described herein is a device for recovering an object from water comprising an object attachment point, for attaching the device to the object, and an inflatable and/or buoyant target mesh element, the attachment point and target mesh element being linked by an extendible line portion which is extendible when placed under longitudinal pressure. Such a “Man Overboard Recovery System” allows a vessel to remain under proper control in difficult weather conditions when dealing with a casualty recovery situation.
Abstract:
Methods for monitoring windlass rotation are provided to determine the real time rate and length of rode release when anchoring a boat. The rotation can be monitored in real time using directional sound and/or electromagnetic radiation receivers and/or transmitters that can be in a module attached to the windlass. Another windlass module can monitor windlass rotation using micro-electromechanical systems (MEMS) components such as accelerometers, magnetometers, gyroscopes, and/or inertial measurement units (IMU) to sense motion and/or position.
Abstract:
Devices, systems and methods for real-time wave monitoring are described. One example system for real-time monitoring of wave conditions includes a plurality of buoys, wherein each of the plurality of buoys comprises a sensor array configured to continuously monitor one or more characteristics of the wave conditions, a transceiver configured to transmit, to a remote server, information corresponding to the one or more characteristics of the wave conditions over a wireless communication channel, and a tether that physically couples the buoy to an anchor, wherein the information from each of the plurality of buoys is combined with a user preference to provide a user with a message regarding the wave conditions in response to a user request, and wherein a duration between the user request and transmission of the information from each of the plurality of buoys is less than a predetermined value.
Abstract:
In a water buoy, a power system generates electrical energy from water kinetics and transfers the electrical energy to a sensor array, processing circuitry, and communication interface. In the water buoy, the sensor array detects buoy locations, water velocities, water velocity directions, and wind speeds. In the water buoy, the processing circuitry aggregates the detected buoy locations, the detected water velocities, the detected water velocity directions, and the detected wind speeds into data messages. In the water buoy, the communication interface wirelessly transfers the data messages for delivery to a computer system.
Abstract:
A boat includes: a propulsion device configured to generate propulsion force for a vessel body from driving force from an engine; a detection unit configured to detect a current position, a bow direction, and a movement speed of the vessel body; a steering device configured to change a cruising direction of the vessel body; a steering sensor configured to detect an operation amount of the steering device; and a control device that is connected to the propulsion device, the detection unit, and the steering sensor, and is configured to acquire an operating status of the propulsion device and a detection result obtained by the detection unit and the steering sensor, and to control the propulsion device based on the detection result. The control device executes a turning operation with the propulsion device, when the operation amount of the steering device detected by the steering sensor exceeds a threshold.

Abstract:
A ship alarm display device that displays a plurality of sets of alarm information to be easily understood is provided. An alarm information acquiring module acquires the alarm information from apparatuses installed in a ship. A transmission source classification list memory stores transmission source classification lists obtained by associating each apparatus with a transmission source category. An importance list memory stores importance lists obtained by associating the alarm information with a level of importance. A display target specifying module specifies the transmission category and the level of importance as a display target. An information selecting module selects the alarm information corresponding to the specified display target from the plurality of sets of alarm information stored in memory, based on the transmission source classification lists and the importance lists. An alarm information displaying module displays only the selected alarm information in a list, on a display unit.
Abstract:
Systems and methods for displaying a marine signaling device are disclosed. A flag coupled to a top section of a telescoping shaft includes a folding arm pivotally coupled to the top section that folds upward to gather the flag into alignment with the telescoping shaft. A housing couples to a boat and supports the shaft in the display configuration and receives the shaft in the storage configuration. As the shaft is retracted, the folding arm contacts an upper surface of the housing and gathers the flag into alignment with the shaft. A motor automatically extends/retracts the shaft based on detected tension on a tow rope mount of the boat or a tow rope coupled to the boat. A tension switch detects tension and activates the motor based on the detected tension. The tension switch may include arms that rotate in response to tension to activate a limit switch.
Abstract:
An apparatus provides a warning of propeller rotation or CO/CO2 hazard in a marine craft and includes a sensor in communication with the propeller to directly or indirectly sense rotation of the propeller and to generate a signal in response to the hazard, a controller coupled to the sensor to process the signal from the sensor, and a sensory alarm coupled to the controller to generate a warning alarm signal when the sensor returns a signal indicative of a predetermined state of hazard, namely actual rotation of the propeller from a nonzero rpm to a user or factory defined rpm or CO/CO2 levels at or above a predetermined maximum.
