That sounds like it would be great for making your anchor visible, but doesn't it create problems with setting and maintaining a good set? Where do you attach the buoy line, to the crown, or the end of the shank? I guess if you use a small buoy the buoyancy would be completely overcome by the weight of the anchor and chain, but still seems a little iffy. I can see myself losing sleep, worrying about the buoy pulling the anchor out.
