For kicks I decided I was going to try out some gunboats to see if I'd like to play them before investing in the money in multiplayer. I launched singleplayer, went and bough the gunboat, bought the upgrades available at the station (This was the blood dragon gunboat at both Mito and in Chugoku). When I went to undock, the doors seemed to "catch" the gunboat, causing me to become locked in the base's docking bay. I tried about 30 times and this repeatedly happened.
I even tried to wait for a friendly ship to dock and attempt to escape but to no avail. Is the only way around this to have someone else undock ahead of you to ensure the doors are open?

singleplayer doesnt have some of the undocking points we have on the serve, so large ships get stuck much more easily. This rarely happens on the server though, and when it does you can spam tab and W while undocking to loose yourself from the base.
Get ioncross and just move your character to a planet after you buy the ship.
