Lovely sense of tranquillity; the almost mirror smooth water provides a good reflection of the details of the boat. I like the way you've positioned the boat within the frame, having a lot of water surrounding it on one side; it draws the eye in rather than just "hitting" it as a centred arrangement would. The water's not solid enough in colour to be boring, and the lack of a distinct interrupting line like a horizon increases the peacefulness of the mood.
