A hull assembly for a pontoon boat includes a hull extending in a longitudinal direction between a front end and a rear end. A first thruster assembly is attached to a first lateral side of the hull. A second thruster assembly is attached to a second lateral side of the hull. The first and second thruster assemblies include respective thrust units that are each movable between a deployed position and a stowed position.

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.

A floating support device (1) for a photovoltaic panel, includes: a structure (2) including coupling elements (3) for coupling to other floating devices in such a way as to allow a network (R) of floating devices to be formed; one or a plurality of floats (4), intended to ensure that the device does float, which are rigidly connected to the structure (2); and elements for holding at least one photovoltaic panel (P), and in which the structure is an element separate from the float(s) so as to allow forces to be transmitted between the floating devices of the network without transmitting the forces from the network to the float(s).

A mooring system including a plurality of connected floats and weights being positively buoyant on a water surface and being negatively buoyant at a depth below the water surface. The mooring system also includes a trigger mechanism arranged to reduce the buoyancy of a portion of the connected floats and weights from a being positively buoyant to negatively buoyant to cause the portion of the connected floats and weights to sink below the water surface where the trigger mechanism changes the buoyance of the portion of the connected floats and weights by either adding a weight to one end or separating the end from a buoyant element.

A floating body includes a main body having first and second surfaces opposite to each other and a first side surface connecting the first and second surfaces and first and second joining parts located on the first side surface to be opposite to each other in a first direction parallel to a ridge line defined by the first surface and the first side surface. The first and second joining parts each include a first portion located on the first side surface and a second portion connected to the first portion to face the first side surface. End portions of the first and second joining parts face each other. A minimum distance between the end portions is greater than twice a width of the second portion in the first direction, and is smaller than a minimum distance between the first portions of the first and second joining parts.

A floating solar plant supporting photovoltaic panels, resulting from the assembly of structural modules and floating modules on a body of water, forming a network of floating support devices supporting photovoltaic panels. The network including at least: a first row of floating support devices supporting a first row of photovoltaic panels, a second row of floating support devices supporting a second row of photovoltaic panels, and wherein the first row of photovoltaic panels and the second row of photovoltaic panels are spaced apart according to the transverse direction, perpendicular to the longitudinal direction by structural modules, and wherein at least the structural modules ensuring the spacing between the first row of photovoltaic panels and the second row of photovoltaic panels are configured so as to be immersed, at least during the passage of a servicing unit.

A catamaran for a wheelchair has two parallel pontoons secured abeam a bow beam and a wheelchair engaging framework for selective attachment and submersion of a wheelchair in water between the pontoons behind the bow beam in use. The catamaran is able to engage a wheelchair in a simple and convenient manner for recreational water sport use by those of limited mobility.
