From my point of view the photo is not bad.
The colors are okay because they reflect the natural situation: the blue of the white part of the boat is absolutely normal as this part is in the shadow, the orange reflection on the sea is obviously the reflection of the sky, even if, yes, it could look a little strange.
The attention is drawn by the high light in the right, I agree.
I like the tonality of the clouds.
I think that this photo could have more chance to be accepted if you crop it a little the up part to remove the lighter part, and the right part to remove 40% of the high light.
Then the boat will be more centered, so more present.
Maybe you could increasing light and contrast on the boat will help a little.
