Just a cautionary note to be careful not to use too much white paint in watercolor when creating highlights.  Use in moderation, normally towards the end of the painting, just to pick up a few brighter areas in a sunlit scene.  So here, masts, rigging gets the treatment.  Don't over do it, especially with weak white paint that dries like a grey, milky colour.

An imaginary scene based perhaps on somewhere in Cornwall, UK.
