^Then what happens if 2 Polaris class ships need to dock?
Then they would have to find a workaround. They're not Star Trek
ships; they can't do everything at any time. Nor are they military spacecraft designed to operate as part of a fleet of ships. I'm not even sure how many Zodiac class ships exist; they're not turned out on an assembly line and may almost never encounter one another. How often did Serenity
hard-dock with another Firefly class ship?
Why would they have
to dock? There are large hatches for cargo transfer as well as hatches for crew and work craft. It's also not unreasonable that ships other than the landing boats might under some circumstances have access to those docking areas.
