A floating solar photovoltaic array having an energy management power control system configured to send power clipped by an inverter to the at least one powered accessory device which can be an aerator, a diffuser, a sub-surface agitator, a sub-surface water circulator, a sub-surface positioning/mooring system, a water quality sensor; a panel washer, or a bird removal system. The array has inflatable pontoons and an air manifold system which is powered by the solar photovoltaic modules can be used to adjust the angle of inclination of the solar photovoltaic modules to the sun. The powered accessories can also be powered by unclipped power or on-shore power or combinations thereof which can be controllably adjusted by the energy management control system over time.

Embodiments include a retrofit pontoon system including a pontoon, the pontoon having a pontoon body defining a first cavity, the pontoon body having a first aperture; a retrofit assembly, the retrofit assembly including a selectively fillable container sized to pass through the first aperture; and a pump. The pump is operably coupled with the selectively fillable container such that operation of the pump selectively fills and drains water from the selectively fillable container, wherein filling the selectively fillable container lowers the profile of the pontoon in the water and emptying the selectively fillable container raises the profile of the pontoon in the water.

A flat catamaran watercraft construction is provided having a bow that defines a “split V” configuration in which the bottom surface of each of the two asymmetrical catamaran hull portions at the forward section of each hull portion slope upward from the inboard side of the hull portion to the outboard side of the hull portion. Such upward slope of the bottom of each hull portion sheds water and waves to the outboard sides of the vessel as it travels through the water in order to minimize the amount of water and spray that is directed upward between the individual hull portions towards the passengers. The rear portions of each such hull portion define an angled slope along both inboard and outboard sides, which angled slopes allow the rear portion of the watercraft to slide and drift sideways along the surface of the water as the watercraft turns. The flat catamaran hull portions and deck of the watercraft are preferably of unibody construction, such that they are formed (e.g., molded or otherwise machined) in a single, one-piece assembly.

A floating body to which an aquatic or marine facility is installed or which is connected to a lower part of the aquatic or marine facility to hold the aquatic or marine facility on water or the sea is proposed. The floating body may include a main floating body which floats on water or the sea by using buoyancy, and a magnet provided on a first vertical side of the main floating body. The floating body may also include a coupling member provided on an opposite vertical side of the main floating body by corresponding to a magnet of another floating body such that the coupling member is coupled thereto, and a mooring line installed on a part of the main floating body to moor and hold the main floating body on water or the sea.

The present invention provides an apparatus, method and system for utilizing commercial cargo containers. The present invention utilizes containers made autonomous by coupling a container with a detachable propulsion system, having a motor and navigation and steering controls, permitting the rapid, controlled, efficient and safe delivery of cargo containers individually by water. Ballast units, deployment systems and control via remote units are also disclosed. The containers, utilizing their inherent buoyancy, can move autonomously according to a preplanned or remote controlled route to a specific location.
