Here is my solution.
It finishes in about 5 seconds. That’s fast enough for me, so I didn’t try any optimizations. There is a another puzzle that better needs my optimization efforts.
UPDATE: I realized that it is much faster to first test that the lower right corner of the ship fits. My optimized solution reduces the runtime to 0.8 seconds.
