Deck Plan

A Deck Plan is a schematic or blueprint of a sophontic object, typically a ship, smallcraft, or vehicle.

• It is a central feature of Naval Architecture.

Description (Specifications)

The creation of starship deck plans is based on the assumption that one ton of mass displacement equals fourteen cubic meters. The standard displacement ton used for these calculations is derived from the volume of liquid hydrogen, the fuel source for most standard star faring vessels.

The square grid scale used on most deck plans is 1.5 meters on a side. Clearance between decks is normally 3 meters. This means that two floor squares, extended floor to ceiling, equals four 1.5 meter cubes or nearly 14 cubic meters (1.5 x 1.5 x 1.5 x 4 = 13.5 cubic meters), or one ton. A 100 dton starship would thus contain approximately two hundred grid squares within.

Allowances of approximately + or - 10% were made in most areas to allow for better representation of specific parts of the ship and to cover various anomalies. For example, crew quarters call for four tons per sophont: the actual tonnage allocated on many plans is often less than that, but additional area is devoted to communal areas such as galley, mess, wardroom, and recreation areas.

Also, a limited volume of passages has been added to some starships. Passages and access ways which have no other use may be safely added to a ship without affecting volume or displacement for construction purposes. These additional passages should amount to no more than an additional 10% of the ship's total volume.

History & Background (Dossier)

Deck plans, blueprints, engineering schematics... they are all part of successful engineering design and documentation practices. Every successful and technically competent sophont society uses them. And naval architects use them extensively. The Travellers' Naval Architecture Society mandates the use of deck plans throughout Charted Space and is the dominant regulatory body for space and starship architecture across polities, sophont species, and the greater, shared interstellar civilization.

Horizontal vs. Vertical Deck Plans

In space, the only "up" is towards the direction of travel while the "up" in a gravity well is to center mass. This has long been a consideration within schools of naval architecture. Ships dedicated to space travel tend to orient towards the direction of travel until the development of the grav plate. Aircraft, Interface Craft or Spaceplanes, and those spacecraft needing to make planetary landings tend to orient horizontally. Its cheaper to orient vertically towards the direction of travel, even with grav plate technology... The culture of Charted Space tends to build craft with horizontally oriented designs, but does it have to be that way?
