A water activity board is described, comprising: a. a plurality of sensors, b. a data unit interconnected to the sensors. c. a communication unit interconnected to the data unit. wherein the communication unit is configured to communicate to a cloud-based database. In some embodiments the sensors are selected from a group consisting of Environmental sensors, sea platform sensors and User sensors.

The main components of an exemplary inventive simulation are a towing platform (such as a ship), a towed body, an underwater vehicle (such as a UUV), and a tow cable connecting the towing platform and the towed body. An objective of the dynamic arrangement of the components is to perform a “line capture” of the moving vehicle by the cable. Respective motions and positions of the towing platform and the towed body affect the cable. Waves and currents in the water, as well as changes in catenary and tension of the cable, affect the tow body. Advantageously, the invention more accurately accounts not only for continuities, but also for discontinuities, characterizing the dynamic interrelationships between and among the components. Among the invention's features is its ability to “trigger” consideration of certain dynamic manifestations relating to the vehicle, depending on whether or not the vehicle is in a captured state.

This application relates to an apparatus for tracking location using a control platform of a small buoy for simulating marine pollutants, in which at least one small observation buoy floats on the ocean, and a relay buoy collects location information from the observation buoy and provides the collected location information to a weather information management server. The apparatus may include at least one observation buoy and a relay buoy, the observation buoy including a GPS receiver which receives a signal transmitted from a GPS satellite and generate location information. The apparatus may also include a communicator performing wireless transmission and reception of signals with the relay buoy, and a power source providing driving power to the GPS receiver and the communicator. The relay buoy may receive location information from the at least one observation buoy and provide the received location information to a weather information management server.

A method for situation awareness is provided. The method comprises: preparing a neural network trained by a learning set, wherein the learning set includes a plurality of maritime images and maritime information including object type information which includes a first type index for a vessel, a second type index for a water surface and a third type index for a ground surface, and distance level information which includes a first level index indicating that a distance is undefined, a second level index indicating a first distance range and a third level index indicating a second distance range greater than the first distance range; obtaining a target maritime image generated from a camera; and determining a distance of a target vessel based on the distance level index of the maritime information being outputted from the neural network which receives the target maritime image and having the first type index.

Techniques are disclosed for systems and methods to provide sailing information to users of a mobile structure. A sailing user interface system includes a logic device configured to communicate with a compass or orientation sensor, a wind sensor, and/or a speed sensor. Sensor signals provided by the various sensors are used to determine a heading and a wind direction for the mobile structure. The wind direction and heading may be used to generate a steering guide display view. The steering guide graphically indicates the heading of the mobile structure relative to various optimum velocity made good (VMG) headings associated with the mobile structure, its heading, the wind direction, and/or a performance contour for the mobile structure. The steering guide may be displayed to a user to refine manual operation of the mobile structure, and the information rendered in the steering guide may be used to autopilot the mobile structure.

A holding apparatus is provided by way of which a hydrofoil surface apparatus can be retracted and extended and/or folded, out of a rest and/or starting position into its operating position and/or out of the operating position into the rest and/or starting position. Such actuation can take place manually by way of a person operating the water sports device, with the advantage of simpler transportability of the water sports device. The water sports device can already be placed in water close to the bank or beach, and can be guided or moved from there in the direction of deeper water. As soon as sufficiently deep water is reached, the hydrofoil surface apparatus can be transferred via the holding apparatus into the operating position.
