Colonia is 60 hours from the bubble, or 88 by top-speed carrier, so probably more like 50% slower once you get into the longer distances. Still pretty close for keeping things to round numbers.
On the other hand, you pay a flat fee for the trip, rather than a fraction of your ship value. And you can use more than one carrier to make the jump...
Hmm, interesting option here: get 44 carriers positioned on the Colonia-Sol route so that they can jump in relays, and start their jump sequences on a fixed schedule about five minutes apart.
- fleet docks with carrier 0
- carrier 0 jumps to carrier 1's planet
- fleet rapidly redocks to carrier 1
- carrier 1 jumps to carrier 2's planet
...etc until Colonia
Could probably get a ship to Colonia in four hours that way, which is a fair bit slower than the record for a stripped-down neutron jump route, but pretty good for a fully laden cargo or combat ship and much faster than ship transfer. Also lots of racing fun since you've only got five minutes to do each transfer, so you've got to be quick!
Announce that you'll pay twice the market rate for it at system X, get other people to mine it for you while you sleep.
The
original explorers were really enthusiastic pre-1.0-release about the concept of exploration involving difficult logistics challenges, and I think it's great that Frontier have
finally gone back and given them some content [1]. If the more modern "instant gratification" explorers don't have a use for it they can still stick to flying paper ships with a 70LY jump range and no support requirements and having fun that way.
[1] I hope some of them are still around to enjoy it after five years...
