A water buoy data system transfers shoaling status. Water buoys sense water characteristics at a location. The water buoys wirelessly transfer data messages that indicate the water characteristics at the location for delivery to a computer system. The computer system receives the data messages wirelessly transferred by the water buoys that indicate the water characteristics at the location. The computer system generates and transfers the shoaling status for the location based on the water characteristics at the location.

Water buoys sense water characteristics and wirelessly transfer the water characteristics for delivery to a computer system. The computer system receives the water characteristics wirelessly transferred by the water buoys. The computer system receives a location and a user water condition preference transferred by a user communication device. The computer system processes the water characteristics, the location, and the user water condition preference, and in response, generates and transfers water condition information for the location for delivery to the user communication device.

A water buoy data system stabilizes an offshore vessel. Water buoys sense wind characteristics and water characteristics at a location of the vessel. The water buoys wirelessly transfer data messages that indicate the wind characteristics and water characteristics at the location of the vessel for delivery to a computer system.

The computer system indicates the wave forces to control vessel engine thrusters to counter the wave forces and stabilize the vessel.

Methods and apparatus 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 transmitter 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.

The various embodiments herein provide a safety device for anticipating and detecting a potential incident in a water body. The safety device comprises a sensor unit, a processing unit, a data transceiver and a computer readable program. The sensor unit is installed over a surface of the safety device to monitor a human and a water vehicle activity and assess a water condition in a device's vicinity. The processing unit is a core module connected to the sensor unit within a housing to receive, process and transmit a data in a real time. The data transceiver is connected to the processing unit through a bidirectional channel to a monitoring authority. The computer readable program is installed in the safety device and runs over the processing unit. The computer readable program acts as an interface between the safety device and the monitoring authorities.

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.
