I invested 26 years to sailing hobby and I loved the idea , living in a boat at a marina at winter time more than anything. I love their whiteness contrasted on dark sky and dark sea so much.
I can see that the day is overcast which is no help to you when shooting a picture like this. To my eyes the boats are the main focus point and as such I find the floating dock on the RHS a major distraction. Perhaps on another day when the light is better this shot could really sing.
