====== Star ship sizes ======

Being nice and simple, **Full Thrust** tends to be a
straightforward system to convert various science fiction
settings to. There are plenty of conversions to be found
on the Web, including my own 
[[starwars/index|Star Wars]] -  conversions.



However, **Full Thrust's** simplicity also causes
problems. Nowhere in the rules are real world scales
mentioned, leaving people to guess how much mass the
//Nostalgia for Infinity// or //Lexx// would
have within the game. Given the

[[http://www.merzo.net|wide range]] - 
of ship sizes available, this can make things a wee
bit complicated.



Mostly in order to try and rationalise my own
conversions, I've laid down my own thoughts on how
things might work.

====== First Principles ======



First principles are always good. We can start by taking
something we know, and working from there. I'm assuming
by the way, that a //mass// is a measure of volume, so
two ships of the same mass will be about the same size.



The //Fleet Book// gives ship sizes in tonnes, with
1 mass = 100 tonnes. Though this suggests mass rather than
volume, Traveller uses tonnes to equal displacement tonnes,
and so I shall assume the same.



A bay for a single fighter takes up 1.5 mass. The generic
rules for bays says that a bay will take up 1.5 x the mass
of the ship it contains, so a fighter can be assumed to
be around mass 1.



Assume 20m x 5m x 5m = 500m^3.

====== Example ships ======



Imperial Star Destroyer, 65,000,000m^3.



Millenium Falcon, 5,000m^3.



Traveller Beowulf Class Free Trader. 2,800m^3.
