And you'll do what with 25kt of something once you get there? I can see loading up missions, but I can't really see how much time savings are possible, and then you have to resolve whether or not you can board during the warm-up cycle.
You can't easily switch ships if you have cargo/passengers onboard unless it's cargo when you can switch to a ship with a larger hold. And there's still a 20 mission cap?
Is there any evidence that the Carrier can trade directly with a station?
Sounds like a shuttle situation that could be a rather tedious and long process.
I'm still not convinced there's going to be a huge time savings and increases in cr/hr.
I really just want the ability to take my fleet with me when I move about. If that's reasonably affordable and convenient, I'll be happy.
If there was a reason to take 25kt of something to Hutton the most efficient way at the moment is to use a Python. It's also the best way to ferry it from your carrier too. With a completely cargo orientated ship (no shields just cargo racks) that's going to take around 85 trips.
Using the Python alone the standard Hutton trip is close to 90 minutes, let's call it 85 minutes (I forget the exact figure) that's around 120 hours supercruise in Alpha Centauri and a 5 minute turnaround time adds another 7 hours , So the total is around 127 hours. That is assuming that you can source all the goods within 1 jump.
With a carrier you could use a shieldless T9 to load up in 32 trips. Assuming 10 minute round trips that's less than 5.5 hours to load up. An hour to jump from pretty much anywhere in the surrounding 500 ly. Then assuming 10 minute turnaround ferry trips with your Python, just over 14 hours to unload.. If I generously round that up to 14.5 that takes the total to 21 hours which I think most people will agree is considerably quicker than 127 hours.
Of course there isn't any reason at the moment to do such a thing, but in the event of a CG or Operation Ida type of situation it makes sense and there would be the added bonus of having other players helping in the loading and unloading. With the right pricing everyone would make a profit, though it might not be the maximum profit for the FC owner the chances are that one trip like that would cover their weekly expenses
