Hi Quincylvania,
I notice you tend to add the parking=yes tag for slipways and access points that have nearby car parking available. I would recommend not using this tag on elements which do not have the tag amenity=parking. It's customary in OSM to map parking separately from business, building, and other amenity elements.

parking=yes and parking=no are considered a common tagging errors according to the Wiki: https://wiki.openstreetmap.org/wiki/Key%3Aparking
