I'm a little confused by the size referencs. If I was to build ships that look like the reference picture and with the little shadow of a ship as a size guide then I think that some of these would be bigger than my Retribution battleship!
I just have warships now but want to get some cargo carriers of my own. I think the pictures above the data cards look cool so that I would try to match that look. I have never built things this small, but maybe balsa wood can be cut down for a bow, and other ship parts to fill in the middle of a carge carrier.
I also wonder that such large ships have such small gun ranges. Would not a big Galleon have bigger guns to protect such a big ship better?
The guy I game with has all kinds of cargo ships that he says he bought from different game systems and adapted to this one. Can I buy some other make of ship and make them fit these new ship descriptions?

I want to surprise my friends soon with my new additions.
I only just started reading the magazines and I really like the look and all the reading.
My friend wants his computer back so thanks guys.
