Described herein are examples of buoyancy supplements. A buoyancy supplement may include a system including a front flotation portion including a front deck having a front surface, a rear flotation portion including a rear deck having a rear surface. One or both front and rear surfaces having an accessory attachment point, a through-hole substantially parallel to the front or rear surface, a mounting apparatus, a tie-down anchor, and a first and second runner each having a first end configured to attach to the front flotation portion and a second end configured to attach to the rear flotation portion. The front flotation portion and the rear flotation portion may be configured to attach to a float tube.

A boat in which at least a portion of at least one of the port side and the starboard side of the hull is moveable between a first position and a second position. In the first position the moveable portion forms a generally upright portion of the port or starboard side of the hull, and, in the second position, the moveable portion forms a generally horizontal deck surface. A walkway connects a seating area within the boat to an area aft of the seating area, and at least a portion of the walkway is adjacent to the moveable portion of the port or starboard side. A first seat is positioned adjacent to at least a portion of the walkway and a removable seat is configured to be positioned over the walkway and adjacent to the first seat.

A field configurable autonomous vehicle includes modular elements and attachable components. The vehicle can be assembled from these modular elements and components to meet desired mission and performance characteristics without the need to purchase specially designed vehicles for each mission. The vehicle can include a mechanisms that magnetically attach and release configurable elements from the vehicle.

Disclosed is a device for connecting two parts of a ship hull, including: a first frame intended to be integral with a first part of the hull; a second frame intended to be integral with a second part of the hull; a tenon integral with the first frame; a mortise arranged in the second frame and able to receive the tenon as a result of a relative translation of the two frames towards each other in a longitudinal direction of insertion; and a pin which is able to be engaged, on the one hand, into a transverse housing provided in the second frame and opening into the mortise and, on the other hand, into a transverse through-hole provided in the tenon, so as to hold the tenon in the mortise. Also disclosed is a hull of a ship including such a device.

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.
