USCG Light List for your area
The published Light List has all LIGHTED buoys as well as lighthouses. Several thousand entries are in each volume covering a large area.It can be purchased for about $30-35, or it can be downloaded- I forget the link, do a Google search. If you can't find it, reply and I will look. The problem with the download is that the INDEX is NOT INCLUDED and you need to scan the pages for a particular geographical area to find the buoy of interest. That is the way it was a couple of years ago, maybe now it it different.Rich
