Your specific words were "hold zero speed over ground in 5 knot current". If you are holding zero speed in 5 mph current, yes your free anchor and line will be dragged under your boat.
BTW I specifically used the speed of 5 mph, not 5 knots.
Now you can rattle on and on about the details. But this is what you said.
Show me the math I don't believe you. In my response I specifically said I was using chain, you have switched to line in a desperate attempt to dig yourself out of a credibility hole. Go back and read my post. Quote me, don't paraphrase.
If I power up on a dragging anchor and chain until neutral speed over the bottom is acheived, all I have done is take the strain off the anchor chain. There might be some chain under the bow, but unless you're using a planing or displacement anchor, it's not flying flat out behind me.
If you're so certain I'm wrong, show me the math. Show me how the drag on the anchor chain has lifted the anchor off the bottom and flung it out behind me like a kangaroo playing leap frog. Your physics are broken.
Yes, I said 5 knot current, that's because I'm a sailor not a trucker.
If you say I'm using all line and no chain it means I'm on a tiny 2000 lb or less boat (like my Bay Hen) and there is no windlass to jam, I just hand bomb the anchor because I'm not frail.
By the way, I'm practicing my anchoring techniques right now. Sand Bottom, all line
