A spreadsheet for using canon-ish rules to design KnightHawks ships: civilian ship, paramilitary ships, and military ships.  The rules were heavily inspired, influenced, and copied from previous design rules such as Expanded Ship Design (Kveldulf for engine efficiency /ADF calculations), KH:INT (Rob), and Shadow Shacks house rules foradditional systems.

Note on Canon-ish: can't use canon rules to create Military or Paramilitary ships (Paramilitary ships from Dragon.) So, tried to define rules that get one close... 

It is implemented using OpenOffice 3 Calc (spreadsheet) for multi-platform (my work is on OS X.)
