A vessel includes a body, such as surfboard, that floats in water. One or more thrusters, and one or more sensors are provided on the body. A controller is configured to selectively activate the thrusters to cause the vessel to move along a path through the water, receive sensor data from the one or more sensors while the vessel is moving along the path, determine, based on the sensor data, whether a dangerous condition is present in the water; and output a warning when the dangerous condition is present in the water. For example, the collected sensor data may relate to locations and directions of currents in the water, the dangerous condition may relate to a rip current, and the warning may identify at least one attribute of the rip current. A map identifying a location of the dangerous condition may be generated and forwarded to other devices. 1. A vessel comprising:a body that floats in water, the body including a board,one or more thrusters provided on a bottom surface of the board;one or more sensors provided on the body; and selectively activate the thrusters to cause the vessel to move along a path through the water;', 'receive sensor data from the one or more sensors while the vessel is moving along the path;', 'determine, based on the sensor data, when a dangerous condition is present in the water; and', 'output a warning when the dangerous condition is present in the water., 'a controller configured to2. The vessel of claim 1 , wherein the path extends along a shore claim 1 , the sensor data relates to locations and directions of currents in the water claim 1 , the dangerous condition relates to a rip current claim 1 , and the warning identifies at least one attribute of the rip current.3. The vessel of claim 2 , wherein the controller further identifies at least one of a location of the rip current claim 2 , a velocity of the rip current claim 2 , a width of the rip current claim 2 , a depth of the water at the rip current claim 2 , or a change in the rip ...
