Only by manually selecting destination points to coax it the way you want to go. Not what you want I am sure but the only way. 

If you have noticed, ships move with inertia--they start out slow and build up speed--often if you target or order a move to a different point you can stop the forward motion and start another slow turn/acceleration.  It helps some.  Basically it's pretty similar to parallel parking a car

As GoaFan said, try playing around with the physics of the ship within it's entity file.  You can accomplish this type of turn by adjusting the angular acceleration (lower, I think) and deceleration (higher), but I bet you have to fiddle with the linear values too so the ship still moves fluidly.
