Getting a XR-5 would be a tight squeeze.
How about moving the port 90° down on the side? That way there should be room enough for most craft. If it was on the port side, the trip from the EVA port would be short.
And since this is for crew/cargo transfer only, would it be hard to make the dock "fail" during propulsion? Just undock any craft if main or hover engines are engaged.
Well, once connected no need to EVA, you ingress the ship by crew transfer.
Dock fail would be easy but yet as the Arrow don't have full "realist" system I don't like much to limit users. If one want to travel with apples glued all around in contradiction with all structural and CG constraint, why not ?
What ya think ?
