What constitutes a medium-sized ship, and why did we decide that this ship was going to be medium instead of small or large?

So, yeah, medium is basically... there's medium-large. Basically, once we started looking at what we wanted with the Apollo, which is having several patients and doing this kind of stuff over a large distance, we thought, well, it's too big to be a small ship. And the issue is that even if the Endeavor is massive, like bigger than large, large was too big for what we wanted to do. So medium was basically the sweet spot, even if it's close to some ships that are a bit too small, or some ships that are a bit too close to large. So it's a bit tight, but it's the sweet spot basically to do what we wanted to do, which, well, we will talk about it, and we've seen that in Ship Shape and other stuff. But yeah, the sweet spot on a medium ship is basically going around, but without needing a lot of people with you to do this kind of stuff.

The larger you get, the more extra stuff you have to factor in. They start becoming big targets. So you either need to start throwing turrets all over the place on them, which then, if they're manned turrets, you need spaces for people to be in those manned turrets, you need spaces to get to them. Or you start sort of almost needing larger components to provide that defense, which then just makes it a bigger ship, at which point you're back to being a large one. So medium just fits that goal nicely. And if you compare it to the Cutlass, they're the same sort of width if you factor in the Cutlass's engines, which sort of artificially bloat it, but it is a fair length longer because of the shape of it. Whilst on paper it doesn't seem that much bigger than the Cutlass, there is a lot more usable space in it.
