text: I've had a look at this. My phraseology may be off but compared to other similar areas, the sea polygon needs dragged into the harbour, as currently the harbour does indeed have no water. I'm happy to do this, but yesterday, I drew a polygon with water=salt that seemed to have solved it but was hastily removed. I guess it wasn't right. So if folks are happy, I'll re-do this in a few days after I get an OK reply??
