The present invention relates to a portable and removable cargo net system operable to be installed in compartments or spaces of varying sizes in a vehicle such as a boat. The cargo net may be used to separate cargo from other structures in the cargo space or compartment to (1) prevent damage to the cargo or other structures in the cargo compartment or space and/or (2) to maintain ordered arrangement of the cargo held in the cargo net.

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 method for ship ballasting includes receiving, at a carbon negative energy storage system, input comprising calcium oxide and water and reacting, within a reaction chamber of the carbon negative energy storage system, the calcium oxide and water to release energy and generate calcium hydroxide. The method includes directing, by the carbon negative energy storage system, the released energy to a requesting end user and providing, by the carbon negative energy storage system, the calcium hydroxide to a marine vessel ballasting system. The method includes releasing a mixture of the calcium hydroxide and ballast water from the marine vessel ballasting system into the ocean to sequester atmospheric CO.sub.2.

An apparatus for securely attaching various stowable items on watercraft is provided. The apparatus allows for non-destructively attaching a mount or base to one or both sides of the craft. A number of securing strap configurations can be added to the base, the straps secured to the base so as to limit movement of the strap.

A watercraft accessory operable to be secured to the deck of a paddleboard and provide storage of a plurality of items. The watercraft accessory of the present invention includes a housing having a top, bottom and a plurality of wall integrally formed to create an interior volume. A first storage compartment and a second storage compartment are secured within the rear wall and are slidably mounted thereto. A third storage compartment is secured to a side wall and is configured to provide additional storage. At least one storage compartment is sealably secured within the housing and another is thermally isolated. The housing further includes navigation lights and a bow light secured thereto. An audio player is further provided and the housing includes integral mounts to facilitate securing to the deck of the paddleboard. An internally located power supply provides the necessary electrical power.

A bar gripping assembly is configured to join a bar to a marine accessory on a marine craft. The bar gripping assembly has a single piece housing having an upper housing portion and a lower housing portion. A marine accessory is formed as part of the upper housing portion. A first wall slot and a second wall slot are arranged through the lower housing portion. A hollow portion adjacent to a weakened wall on the lower housing portion that has a lower portion opening and an upper portion. A strap is arranged through the first wall slot, the second wall slot, and around the lower portion opening. The strap compresses the lower housing portion against the bar to join the marine accessory to the marine craft.

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 boating accessory attachment system includes a mechanism that is selectively movable between first and second configurations. In the first configuration, one member of the mechanism is substantially vertical to support a boating accessory above the deck and/or fencing so that the boating accessory is accessible and usable by a occupant in the passenger area of the boat. In the second configuration, the member of the mechanism is rotated approximately ninety degrees to be substantially horizontal so that the mechanism supports the boating accessory above the water for use by someone swimming or lounging adjacent to the boat. A tubular receiver mounted to the underside of the deck facilitates attachment of the mechanism to the boat.

The present invention provides a watersports board rack for attaching to a support member (e.g., hanging down from an overhead support tower) of a boat. The rack may have a low profile, superior padding and an increased contact area compared to current rack systems, as well as at least one strap for securing the board against the padding and a coupler for attaching to the overhead support member. The rack may thus be operable to securely hold up to two watersports boards (e.g., two wakesurf boards) without the usual wear and tear (e.g., dents and scrapes) that occurs from regular contact with the tines of current rack systems. The rack may thus increase the boat's capacity to securely store watersports boards while the boat is in motion, and due to the low profile, the rack will not substantially reduce headroom or require removal from a folding tower before folding the tower down for transporting and storing the boat.

A ship cabin loading capacity measurement method and apparatus thereof, comprises: acquiring point cloud measurement data of a ship cabin; optimizing the point cloud measurement data according to a predetermined point cloud data processing rule, and generating optimized ship cabin point cloud data; calculating said ship cabin point cloud data with a predetermined loading capacity calculation rule, and getting ship cabin loading capacity data. According to the ship cabin loading capacity measurement method of the present invention, the point cloud measurement data can be acquired by a lidar, and processing the point cloud measurement data of the ship cabin with a predetermined point cloud data processing law and a computation law, and as the point cloud data processing law and the computation law can be deployed in a computer device in advance, after point cloud measurement data acquisition, loading capacity of a ship cabin can be acquired quickly and precisely.
