Hello everyone,

To the best of my knowledge deck plan rules in Traveller, except T5 which I do not have, use the same format:

Non-allocated space is used for cargo storage or waste space.

Stateroom displacement tonnage provides passageways, recreation, dining, sleeping, and sanitary facilities.

Airlocks are part of the bridge and/or engineering volume.

With the exception of TNE/T4 none of the other rule sets appear to take in to account access space.

Realistically, deck plans should be drawn in the same way as floor plans for buildings which requires more instructions with the requirements for items like the size of a bed, the space occupied by the bathroom with all the fixtures, how much space the kitchen fixtures take up, etc.

The USN has the following document: NAVSEA Technical Publication T9640-AC-DSP-010/HAB SHIPBOARD HABITABILITY DESIGN CRITERIA AND PRACTICES MANUAL (SURFACE SHIPS) FOR NEW SHIP DESIGNS AND MODERNIZATION
