Which ship is most similar to Serenity?

A few people have told me that it is probably the Freelancer. I think that question somehow came up in my interview, actually, I remember.

I think the Carrack.

Yeah, that's what they were saying, either the Freelancer or the Carrack.

The Carrack kind of in size, but the Freelancer more in spirit, because it's supposed to be a transport. Turns out we didn't rip it off one-to-one.
