A dock building apparatus comprises a cantilever arm (11) having a first portion configured to be supported on a ground area and a second portion for overhanging a construction area. The cantilever arm (11) is displaceable perpendicularly to the length of the cantilever arm. The apparatus further includes a lifting device (19) movable along the cantilever arm for bringing construction materials including foundation members from the ground area to the second portion of the cantilever arm, and a foundation building tool (15) movable along the cantilever arm for installing the foundation members in the construction area.

A water area may be sheltered by installing, at an active boundary of the water area, a plurality of shields mounted on posts, each shield having a lower edge immersed in the water. Each shield may dissipate at least a portion of wave energy approaching the active boundary of the water area. One or more piers may be positioned within the sheltered water area or basin.

A structure includes a bracket affixed to a substrate. A bracket pole member is affixed to the bracket. A bracket back brace is affixed to the bracket. The bracket back brace is affixed to the substrate. In an embodiment, the bracket back brace includes a back brace member having a beveled end with a threaded bolt attached thereto. The threaded bolt being secured through the bracket via a nut. In an embodiment, the bracket back brace is affixed to a strut of the substrate, and the back brace member has a non-beveled end. The non-beveled end is inserted into either (i) a shackle coupling rotatably affixed to a hinge plate affixed to the strut, or (ii) a side-mount collar affixed to the strut.

A solar power system for a marine dock includes a telescoping vertical member affixed to a dock via a bracket. A solar panel is pivotably and rotatably affixed to the top end of the telescoping vertical support. A weatherproof equipment container is affixed to the telescoping vertical support. A meter unit, battery, and inverter are housed within the weatherproof equipment container. First leads connect the solar panel to the meter unit, which is configured to measure and display energy and/or power generated by the solar panel. Second leads are configured so that current is passed through the meter unit to the battery in a charging configuration. A third lead connects one terminal of the battery to a measurement terminal on the meter unit, which is configured to measure and display the output voltage of the battery. Fourth leads connect the battery to the inverter in a discharge configuration.

A multilayer marine wrapping is proposed wherein each layer has a removal strip and the removal strips are staggered, such that a single layer can be removed at a time.

A marine barrier has a line of buoyant column modules, and an impact net attached to and extending between the column modules. First and second lines of buoyant flotation modules are respectively disposed parallel to and on opposing sides of the line of column modules, and are connected to the column modules by legs such that each of the flotation modules is retained between two adjacent ones of the center column modules. When the barrier is floating in a body of water and a moving vessel impacts the impact net, the impact net deflects to transfer a force of the impact to one or more of the column modules and flotation modules, which in turn engage the water to transfer the force of the impact to the water, to arrest the motion of the vessel.

The adjustable dock handle is a device that is adapted to be attached to a top surface or a side surface of a dock, and which includes a handle that is used to help manipulate a boat during a docking process. The end user may easily reach the handle in order to pull the boat into position for mooring, and which will provide the support and stability needed to independently control the boat while docking.
