[@BurningCold] I'll be covering this in my update tomorrow when I put up the OOC, but to give you a shorter answer now: Basically there are three "classes" of manned ships currently in existance: a single-occupancy (or double-occupancy) scout-class ship, a large, bulky colony ship, and a medium-sized vessel used either for twenty-or so passenger transports or cargo. The medium-sized ship is the one we'll be using specifically in Act One of this RP; for that ship, picture something similar to the Serenity in the Firefly universe: a decent-sized freighter which is versatile enough to carry either passengers or various types of cargo.
