Sorry I didn't reply sooner guys. For some reason my e-mail didn't let me know.
As to your question Kaftan, The Manta is roughly 70-100m, for the setting it is the smallest FTL player ship. The others are far larger. If your interested you can find out more about the game here.
Thanks for the praise Hades, I know they are basic but there is some purpose to it as I want them so that people can easily expand on them with programs such as paint that come with their puter :D
