Re: What's with these flat-bottom mooring buoys?
Sounds like the big advantages are "stackable" and "lifting grips" so if you own the mooring field and want to store them all in one neat pile in the winter, stackable beats balls.
Just need one? Can't really see any reason to buy just one stackable part.
