Very pretty shot. Love the whole blue feeling here. Nice and calm and serene. Great mood.
Only things I would change: The focus seems (very) slightly off on the boat. I would like to see it a touch sharper. I know it's hard to do with a low light subject like this.
Also, I would like to see either a. more detail in the boat (don't know if it's possible in this lighting) or b. less detail in the boat (true silhouette).
Oh and (just a personal thing) I hate the border that isn't really a border. Don't understand it.
Scoring (as usual for the POD there is no topic to skew the score so...) I would give this an eight (leaning toward nine)
