Going a little darker would help, this is clearly an evening shot, and you should show that, I think. It feels a little like evening, fiddle until it feels a lot like evening. Remember, viewers were not there -- you remember the scene, so you "see" the photograph the way it was. We need to be hit harder over the head to get that same sensation.
The boat seems out of focus, or blurred by camera shake? Or is that the motion of the boat you were referring to?
I like the scene. When I see it, I get a sense of relaxation and calm, the sailors are all clearly relaxing and having a soothing evening motoring home from some sailing. Also, holy CRAP are there a LOT OF PEOPLE on that boat. They're probably in violation of several laws (too many people aboard, which usually means not enough life jackets aboard and, all too often, the helmsman is a little too drunk).
