I'm Not So Sure, Gary
It depends on where you are. I got so tired of the 30' of chain on my Vision 32, I substituted 6' of coated chain so I could use the winch and a cheek block to lead the rode to it. In SoCal waters, there is little to worry about in the way of rock to chafe and scope takes care of the rest. Danforths buried plenty deep. I decided to try it when I often laid to bow and stern anchors and had no chain on the stern. The stern always set strong even when pulled different directions with the wind and current. I think a lot of chain (or all chain) makes sense when you have a windlass, even more if you have a reversing windlass. But I'm not so sure otherwise. BTW, in San Diego, we had five big boats on one smallish Danforth stern anchor with clocking winds and cross currents. We didn't care if it dragged, it was just to keep us from looping around our own rodes. After two days, it took three dinghies full of guys to disloge that sucker. Must have buried itself several feet. Never dragged either. Rick D.
