This is how i saw it looking....
Just cropped to original size but ticked the 2 little arrows to make it crop in portrait,went to one of the corners and rotated it so the bottom of the box was in line with the sea,cropped so it conformed roughly to the rule of thirds,1/3rd sea 2/3rds sky.
Tried the boat on an intersection but looked to conformist so just left the 3rds composition....
