Interesting. As for the Gallic one, the in-game stations using the model sure look rather small.
With regards to the topic, this is an issue with all ships above a certain size, and can even occur with ships like the Gull, so it's not that it's unheard of, just that it's highly unlikely to get "fixed": the game simply wasn't made for these ships to use the lanes. My suggestion is to just manually dock and try to use the directional keys rather than the mouse to adjust the heading, as they always use the maximum input in a direct angle, making them good for precise adjustments.
