A navigational buoy that includes a finned, hollow, transparent, spherical shell that floats on water. A multi-wheeled motor-unit sits inside the shell, and ballast weights attached to the motor unit cause it to rest on the bottom of the shell. A biasing structure attached to the motor unit, lights, and other aspects are included in some embodiments.

The diver's floating marker assembly is a marker buoy. The diver's floating marker assembly is configured for use in water. The diver's floating marker assembly is a safety device that marks an area in the water where one or more divers are operating. The diver's floating marker assembly is comprises a marker structure, a reel structure, and a tether. The tether attaches to the marker structure. The marker structure is a buoyant structure that visibly marks the area in the water where one or more divers are operating. The reel structure stores, pays out, and retracts the tether. The tether is paid out and retracted by the one or more divers while underneath the water. The use of the reel structure allows the position of the marker structure to be set by the one or more divers while underneath the water.

The invention relates to a buoy comprising a buoyant, plastic core component, and a plurality of detachable flotation components that support and surround the core component. The buoy is preferably more than 2.5 meters diameter, but the diameter of the core component is preferably less than or equal to 2.35 meters diameter. This facilitates transport in a single shipping container. A novel tie bar assembly and novel lifting/mooring mounts are also disclosed.

Maritime threat-sensing buoys include sensors—such as acoustic, radio frequency, visual, or other sensing devices—that track, identify, or classify hypersonic or underwater threats in real time. Some examples of suitable sensing devices include microphones, radio-frequency (“RF”) detectors (for example, RF antennas), infrared detectors, and machine-vision detectors. The maritime threat-sensing buoys may be deployed using aerial or maritime vessels, and may host payloads, such as threat-sensing mechanisms, batteries to power the threat-sensing mechanisms, solar panels configured to deliver electricity or other energy to the batteries or other devices, and other cargo or contents.

A floating observation system includes a floating platform. The floating platform includes an upper deck, upright posts, a device compartment, a ballast compartment, a radome structure and a device installation base. Top ends of the upright posts are connected to the upper deck, and bottom ends of the upright posts are connected to the device compartment. The ballast compartment is connected to the device compartment. The radome structure is borne on the upper deck. The device installation base is arranged on an outer surface of the floating platform. Various types of auxiliary devices are borne by the upper deck and the device compartment on the floating platform. Various observation devices borne by the device installation base are arranged on the outer surface of the floating platform to observe different kinds of information and to observe spaces above, on and under water, thus meeting a demand for comprehensive observation in all dimensions.
