An LED illuminated buoy system is disclosed, designed to enhance maritime safety and visibility. The system includes a weighted base with a conical shape for stability and a semi-translucent flotation part that extends above the waterline. The buoy houses an LED light source within the base, programmable for various colors and patterns. A sealing connection between the base and flotation part prevents water ingress. The system also features a communication interface for data transmission and remote operation. The buoy can be anchored securely and is adaptable for use as a lamp on land. The system's design allows for easy assembly and maintenance, with environmental resistance features integrated for durability. The buoy serves as a navigational aid, safety marker, and versatile lighting solution in aquatic environments.

An inventive channel marker includes a least a buoyant member, a display device, a photovoltaic cell and power storage assembly, and a display device connected to a wireless communication system. The inventive channel marker may also be inflatable. Accordingly, the inventive channel marker facilitates its deployment as a temporary channel marker that can be easily stowed when not in use, and with a display that can be configured on the fly to present any desired information.
