You can use the engine kill command for this purpose (press "Z" or "Y", depending on your keyboard layout). When you do so, your ship will continue to move into the last direction you were heading while you can turn around your ship freely and by this doing a "visual inspection flyby" without ruining someone elses paintjob.
EDIT: in order to being able to kill the engines you need to be in freeflight mode (press escape or the onscreen control left of "go to" ).
