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which has a portion that is wider in cross section than the channel opening, thereby preventing the fastener from being withdrawn from the channel body through the channel opening, and wherein the fastener can be selectively secured to the track system at a selected longitudinal position.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.
