I still got 3 good claw and swivel anchors and chain for sale. Make excellent mooring anchors.
Go get a cheap solar pannel and a cheap gell cell battery And a sunset to sunrise LED 12 volt white light. For the 360 degree light. Never need to worry about morring light. I use solar panel to keep my secondary electronics battery charged completly seperate from starting battery. Pictured
dang... dont have a dog in this fight but it sounds like when you connect up to a mooring ball in a designated mooring area there is no need for an all around lite?...
the op says folks have been mooring in this area for 40 years.. was it ever a designated mooring area?..
