Simple Inland River Navigation Aid

I wanted a simple way to keep track of which side the navigation buoys/channel markers should be relative to my direction of travel on the boat. You know, red right returning and up river/down river stuff. This is more helpful for the less seasoned boaters more than anything. It follows U.S. Inland water/river navigational aid logic, and things may be different for your neck of the woods. For our 650+ miles of river, this is how our aids are laid out. All you have to do is remember to rotate it to the correct orientation once, at the start of your trip. Be sure to spin it around on your way back. I printed this in PLA for now, as I do not have green ASA or PETG. Simply use model glue or super glue to glue the channel marker buoys to the base.
