Puzzle #437 - Nothing To See Here (Yajilin)

This was the 11th Yajilin puzzle from my somewhat recent LMI contest, Yajilin Yacht. A solution video for the contest puzzle can be found on the contest page.

My goals here were to make a laterally symmetric puzzle (instead of the usual rotational symmetry) and to only use zeroes. The result was one of what I view as 2 difficulty mis-steps in Yajilin Yacht, as I should have gone bigger with this puzzle, or moved it earlier. I had expected it to be harder than it was to solve and also wanted to keep it far from Sloop and the result was a drastic difficulty drop two thirds of the way through the contest. Maybe I should have cut it and gone with something else instead to bridge the gap...
