Perhaps if you are dragging towards any shore, your anchor cannot be set correct?
I have not put you in this jam, you are simply presented with a scenario, perhaps you have no solution. Rather you insist to complain that it is not realistic in your area. Perhaps go to an area in the world where it is real.
I did not specify weather it jamed at the splice or not. And you suggesting you have never jamed a windlass? Really...
The scenario is clearly meant to illustrate how dangerous situations come about. It is not the jam, or the current or the close shore that individually creates the issue. Rather it is the combination of many issues that causes the problem.
If you do not know that you cannot engage your engine because your anchor will be dragged under by the current, you are in trouble.
If you have never experienced the scenario, then you have not the experience.. just say so.
Anchoring in tidal currents in the ICW is such a common situation, we can only come to a conclusion you have no experience doing this. So how can you argue this is not realistic.
Just because you are anchored in a tidal current, does not mean you are anchored in a main channel. Quite the contrary, the ICW looks like Swiss cheese in many places, so you are not in any main channel. Furthermore, the ICW itself can have huge tidal currents due to all the inlets having different high tide times.
Your scenarios just keep getting more outrageous with every post. Now you've got me dragging anchor at 5 knots in a 5 knot current with a sandbar 1/4 mile downstream of me and my anchor and chain are so light they are going to get sucked right off the bottom into my screw as soon as I put the engine in gear.
Your solution to this problem (yes, this is your problem, because I wouldn't put myself in this situation, but obviously you would), is to spin your anchored Catalina 40 around 180 degrees through a 5 knot current and back the boat through the current.
You are saying you have had this experience? What kind of propulsion did you have to get your stern swung around against that current? How did your boat respond when she was beam to the 5 knot current with an anchor hanging off the bow? Were you single handed? Were you able to leave the helm unattended while backing through a 5 knot current so you could go forward and clear the jam? That's some fancy boat driving.
Yes, I say so, I have never experienced this scenario.
By the way, if my anchor is dragging with the boat, along the bottom at 5 knots, then as soon as I bring the boat up to 5 knots through the water (0 over the ground), my motion relative to the anchor will be nil. I'll just be holding station, as will the anchor.
Edit: if these are just rhetorical questions and you don't want me to actually respond to them, it probably isn't necessary to quote me in your post and pose the question directly at me.
