@SoloFlyer I have soloed my Carrack but must admit it can be nervewracking - really gotta keep an eye on surroundings when landed in port or planetside, LOTS of hideyholes for would-be ship-jackers and jackholes alike. Sounds like it is also still possible to glitch-force in past the airlock doors under at least some conditions.
If solo, I will run an external view check just before jumping out of the pilot station and leaving the ship to make sure there aren't any one-eyed willies sneaking around (I leave it powered on so the shields are up, side benefit is Carrack makes hydrogen fuel faster than anything else in game) - pay special attention to closing the ramp as I have apparently hit the switch more than once and panicked when I take an external view once in the pilot station and see the ramp open, I will close it and then run a complete security sweep (literally EVERY openable panel or door on all decks including all onboard vehicles) before I leave the armistice zone.
She is a big girl to run solo but assuming no stowaways she's tanky enough, and fast enough in most situations to just bravely run away\carry on course (assuming no EMP's which apparently are running a bit OP right now). Seems to be more fun to run with friends though, just not sure how to share in profits if trading (and they already seem kinda slim compared to risk IMO but not reasonable to ask guys to donate their time) - one way to make that up is take on a few claimjumper missions as a crewed Carrack makes easy work of those and if everyone is running A Call to Arms the bonuses are nice. Alternative would be for everyone to grab package delivery missions form one gravity well to another and let them earn their own wayt and then split fuel costs (Carrack is a little slow in QT on the stock drive but it is ridiculously efficient for a 380 foot long ship).
Keep in mind, I am only just coming back to SC after a hiatus of roughly a year so I am learnnig\relearning a lot myself.
That said, she is an awesome ship, having 2 or 3 ground vehicles, plus a runabout\shuttle just makes it seem so much more incredible - I am running an Ursa, Cyclone, Cyclone-TR and the Pisces as my current fitout and other than being a bit of a pain to load up if solo after a 30K or other crash it is great, tons of flexibility.
