A cover adapted to be reversibly attached over an opening of a storage compartment contained on a personal watercraft. The cover includes a generally planar substrate having formed therein a dry storage chamber and at least one additional feature selected from the group consisting of a cup holder, an equipment rail, a surround tray, an accessory mounting plate, and a magnetic surface.

The present invention includes a folding and telescoping mounting stand apparatus for mounting a Global Positioning System (GPS)/sonar device on a boat, comprising a first outer tubing attached to a base plate which is secured to a deck of a boat, a first inner tubing having a bottom end and a top end, wherein the bottom end is placed in and attached to the first outer tubing by a pin and a first knob and the top end is placed in and attached to a second outer tubing by an intermediate tubing, a second inner tubing attached to a top tube by a second knob, wherein the combination of the second inner tubing and the top tube are placed in the second outer tubing and held in place with a spring plunger, a board connected to a rod and wherein the rod is secured to the top tube and the second inner tubing with the second knob, wherein the inner tubing is raised to a desired height when the spring plunger is pulled and the board is lifted upward; and the apparatus having an upper body above the first outer tubing that is folded down by releasing the first knob and pulling upward on the board until the upper body is 1 above the first outer tubing and then folding the upper body forward to the deck.

The present invention is concerned with a method of transporting a hydroelectric turbine system, and a vessel suitable for use in implementing said method, whereby the vessel comprises a raised or raisable section, which enables the vessel to pass over a portion of a base of the hydroelectric turbine system, when located in a flooded dry dock, which portion of the base projects above the water line in the dock.

The invention relates to a watercraft mounting system that embodies a multi-faceted tube and a mating clamp system adapted to carry an accessory. The designs of the railing and clamp have geometry to prevent rotation while allowing flexibility of adjustment in multiple positions.

An underwater base for handling plural underwater vehicles equipped with seismic sensors for recording seismic signals during a marine seismic survey. The underwater base including a storing part configured to store the plural underwater vehicles; an inlet part located above the storing part and configured to control access of the plural underwater vehicles to the storing part; a control part configured to acoustically guide the plural underwater vehicles to the inlet part; and a support part configured to support the control part, the storing part and the inlet part. The storing part is further configured to receive the plural underwater vehicles as the plural underwater vehicles fall from the inlet part into the storing part.

A system for creating additional storage on a marine vehicle is provided. The system of the present disclosure is generally designed to secure to a marine vehicle via a rod holder, wherein parallel bars provide additional storage area for marine equipment, such as innertubes. To this end, the system of the present disclosure may comprise supports and support braces. Straps may be used to attach the marine equipment to the supports. To ensure that the supports are properly secured within the rod holders, a sleeve may be used to increase friction and change size. Board arms may be attached to the supports in order to increase storage area.

A catamaran lifting apparatus is disclosed for lifting objects in a marine environment. The apparatus includes first and second vessels that are spaced apart during use. A first frame spans between the vessels. A second frame spans between the vessels. The frames are spaced apart and connected to the vessels in a configuration that spaces the vessels apart. The first frame connects to the first vessel with a universal joint and to the second vessel with a hinged connection. The second frame connects to the second vessel with a universal joint and to the first vessel with a hinged or pinned connection. Each of the frames provides a space under the frame and in between the barges that enables a package to be lifted and/or a marine vessel to be positioned in between the barges and under the frames. In this fashion, an object that has been salvaged from the seabed can be placed upon the marine vessel that is positioned in between the barges and under the frames.

A structure is supported by electrostatic forces produced by a shell of one or more capacitors wherein an inner plate, or plates, of like charge define and support an interior volume. When charged, the repelling force of the interior plate(s) are capable of supporting the interior volume under greater pressures than could be withstood otherwise.

Fixation arrangement adapted to releasably fix a wind turbine tower segment (4) to a support (3) of a transport vessel (20), comprising at least two fixation means (2), wherein each fixation means (2) comprises a base member (6) fixed or to be fixed to the support (3), a lever arm (8) connected to the base member (2) and pivotable around a pivot axis (9), and a tensioning means (13) for clamping the lever arm (8) with a clamping section (10) against the tower segment (4), wherein the tensioning means (13) comprises at least one tensioning element (14) supported relative to the base member (6) and movable from a non-clamping position in a clamping position and back, wherein the tensioning element (14) directly or indirectly interacts with the lever arm (8) which is pivoted into a clamping engagement of the clamping section (10) with the tower segment (4) when the tensioning element (14) moves from a non-clamping position into a clamping position and which is released when the tensioning element (14) moves back to the non-clamping position.

A catamaran lifting apparatus is disclosed for lifting objects in a marine environment. The apparatus includes first and second vessels that are spaced apart during use. A first frame spans between the vessels. A second frame spans between the vessels. The frames arc spaced apart and connected to the vessels in a configuration that spaces the vessels apart. The first frame connects to the first vessel with a universal joint and to the second vessel with a hinged connection. The second frame connects to the second vessel with a universal joint and to the first vessel with a hinged or pinned connection. Each of the frames provides a space under the frame and in between the barges that enables a package to be lifted and/or a marine vessel to be positioned in between the barges and under the frames. In this fashion, an object that has been salvaged from the seabed can be placed upon the marine vessel that is positioned in between the barges and under the frames.
