I was bored today and curious, so I loaded up Vassal and tried to work out all the possible moves for the SSD (assuming it moves from the front of the rear base).
I came up with 21 possible moves. 3 naturally (Speed 0-2), 3 either side with a Navigate Dial (so one click), 2 more each side with Moff Jerjerrod (a second click at the first joint), and another 4 each side with Moff Jerjerrod and a Navigate Dial (so ||, | or |, |).
Even without Moff Jerjerrod the ship can move surprisingly far, both forwards and sideways. With Jerry... oh my.
Key:
- Blue - natural moves,
- Green - Navigate Dial (or with Moff Jerjerrod),
- Red - with Moff Jerjerrod,
- Yellow - with Moff Jerjerrod and a Navigate Dial.

Let me know if I've missed any or overlooked something.
