Reflections in the water should form a vertical line with the real thing! At least, I've used this idea succesfully a few times.
The waves blur the picture, of course, but if you look carefully there are a few reflections I think you can use, including those of the leftmost point of the prop circle and the navigation light on top of the tailfin.
Based on this a slight CCW rotation is indeed needed.

Since the wall was built sloped, there is no valid reference in it. I´d use Peter´s advice but with great care. In general I believe the pic is almost level. Maybe some 0,1 or 0,2º CCW will do. Or maybe not. Try it out and if you want post the results here.
I´m a bit more worried, however, about the softness of the image in some parts, specially the blurriness on the right wing. Also be careful with the blown-out whites on the wing edges, for example.
Hope it helps.
