I wonder about the length, and capacity of some ships...
I know we cant know for sure... ships are taken from the star wars wiki, and a lot of ships just have a few texts , and maybe 1 image.
Whilst i get that cruiser/frigate/capital ships, most of them dont have high cargo capacity, because its like rooms over rooms for passengers, confortability (etc ), and etc
also to hold all those big weapons, it takes a lot of space to having operational weapons like cannons, turbolasers , etc ( you get the point ).
first, the length of entities as to be right...
Some ships looks larger then other, then you see their length and ure confused sometimes ( Simiyiar freighter, or XS-800 for example )
:P
For example, The wayfarer-class ship .

Its a new ship on combine, it looks to have quite decent ccargo space.
its length is 82 meters. You can see the big cargo container attached to it.
so if we would calculate the cargo space available for its 'big cargo container',
we can do it like messy using the 82 meters length,
and it would give something in the 20,000 m3 space, ( the least ), upon calculations i made.
What do you think ? :o)
lol im such annoying :-)
