A self-monitoring LED marine navigation light that monitors LED intensity and if the intensity is not COLREG compliant, a microprocessor in the light simulates an open filament just as would an incandescent light, thus allowing the analog ships alarm panel circuit to trigger an alarm. The device generally comprises a base, a lens mounted to the base, and an LED module seated in the base and enclosed by the lens. The LED module includes primary and optional secondary LED lights plus one or more photodiode(s) exposed to the LED light(s). The LED also includes a processor and software for measuring light intensity input to the photodiode(s), comparing measured intensity to a minimum COLREG threshold, and signaling failure when measured intensity falls below said minimum threshold.

Various implementations described herein are directed to providing lighting in an underwater transducer mounted to a boat. The transducer assembly includes a housing. The housing includes a transducer. The housing includes one or more lighting devices. The housing also includes an element integrated with an outer edge of the housing in a waterproof configuration. The element allows light from the one or more lighting devices to emanate outward from the outer edge of the housing.

A lighting fish attracting device includes a fixed support, a solar panel, a battery, a lamp, and at least one floating member that is configured to float on a water surface when in use. The fixed support and the battery are mounted on the at least one floating member. The solar panel and the lamp are mounted on the fixed support. The battery is connected to the lamp and the solar panel. The lamp is located on a dark side of the solar panel, and the dark side is configured to face the water surface when in use.

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.
