A boat hull has one or more track systems integral with a main body of the boat hull, each track system having a longitudinally extending channel comprising: a longitudinally extending channel body; and a longitudinally extending channel opening in communication with the channel body, wherein the channel body is wider in cross-section than the channel opening, the channel body is adapted to receive a fastener which has a portion that is wider in cross section than the channel opening, thereby preventing the fastener from being withdrawn from the channel body through the channel opening, and wherein the fastener can be selectively secured to the track system at a selected longitudinal position. The track systems can be used for mounting boat hull structural parts and other parts and accessories.

A modular crew cabin system includes a plurality of crew cabin modules interchangeably installable within a plurality of spaces within one or more decks of a ship. A crew cabin module can include four walls, a ceiling, a floor, an upper bunk, and a lower bunk. The upper bunk and the lower bunk are disposed adjacent to two different walls in an L-shaped configuration. The ceiling includes a lower portion and a pop-up portion disposed above the upper bunk such that a 6-foot-tall occupant can sit up comfortably within either the upper bunk or the lower bunk. The pop-up portion of the ceiling may extend higher than an industry-standard ceiling height while permitting utility conduits to be routed over the lower portion of the ceiling. Storage space within the crew cabin module may be greater than one cubic meter.

A catamaran oil production apparatus is disclosed for producing oil 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. At least one of the frames supports an oil production platform. One or more risers or riser pipes extends from the seabed (e.g., at a wellhead) to the production platform (or platforms). In one embodiment, the production apparatus includes crew quarters.
