It no more matches all of the evidence than my theory matches all of the evidence.
Hmh? I thought your theory matched all of the evidence, too. That part isn't difficult to do. It's only the power of the theory to account for the greater context that may differ here.
You can't compare real-world sea-going freighters to fictional space freighters.
Why not? It's great for expounding on the potential differences, and then expanding on those.
Why do you believe there's no shuttle? Would make sense to have this to travel surface to orbit, rather than taking down the stardrive section of the freighter.
Indeed, the design of the tug part of the ENT
Horizon may be taken to suggest a separable shuttlelike section, at the very top. But possibly for emergency use only.
The issue of how the cargo gets up there, and back down again, is an interesting one. It's ore, so clearly it isn't being optimized for minimum weight. Does this just mean it's being moved up and down by the engines of the ship, engines that certainly should have enough power to juggle mere petatons of mass against one gee if they can hurl the ship between planets and perhaps stars? The one problem with that is the shape of the ship, with engines clustered in one end - certainly not a big problem for 23rd or 24th century sublight propulsion that requires no rocket nozzles at the thrust axis, but a potential counterindication to 22nd century liftoff tech (at least the Kelvin timeline version of it).
Big transporters sound rather likely. It
is just dumb ore - no worries about scrambling some of it. And the containers of the equally large Class Y are of a more manageable size and might be stevedored down to the surface one by one, for moving the apparently more delicate general goods carried by the likes of the
Fortunate. But surface-to-orbit machinery forms a minimal part of Trek surface-to-orbit craft anyway: shuttles are just lots of empty space with tiny engines glued on. Every ore container could be a landing-capable shuttle on its own right, at little extra cost, and without need for "harbor tugs" or "forklifts" of any sort.
More likely still, the crew uses the orbital transportation infrastructure of whatever planet they're orbiting. Modern day freighters don't carry cars so the crew can get around once they arrive at a port.
This is great for freighters shuttling between civilized ports. Perhaps not so great for Boomers hunting for markets in the far frontier. Potentially crippling for poor
Franklin who was supposed to be pushing the frontiers!
