I didn't want to pigeon hole you into having presented a specific look, but you forced me to so here you go.
It has a watercolor/pastel look that creates a gritty look, typically seafaring scenes are either calm and serene or choppy and perilous, you've managed to create a combination within one composition; think about how the water swirls in the background and the sailboat cuts cleanly through the swirls. I was thinking that some of the bottom could be cropped out but I like how the boat cuts through the middle of the image.
