Lee, that was excellent insight.
I believe you are exactly right and I made a note to do just that the next time
I pull the hook up.
I do have one shackle connecting the swivel to the anchor but having a length
of chain sound like a real winner.
Thanks...

The swivels are usually installed direct to the anchor. They break during a
side pull. They might be OK if several shackles or chain links we in between
the swivel and anchor to allow swinging to the side without binding.

That sound good to me.
The chain and anchor and shackle are another problem.
Ann-Marie went aground in Hurricane Hugo when the chain parted company from the
anchor. She never found the anchor so she doesn't know if the chain or the
shackle broke. It broke when the hull was sideways to the oncoming seas due to
tacking at anchor. so the forces were at peak. He ended up in the woods at
the edge of the marsh and it cost about $20K to drag the boat back to the
river.
My friend Capt Ron lost his anchor in Key West in "the storm of the century"
some years ogo. He did recover his anchor and the shackle was not there.
Other folks have advised me not to use a swivel as it is a weak point.
I have been told that all shackles are "high tensile" as in high tensile
chain. Can anyone confirm that?

Norm, I'm in NC and we have had more hurricanes than any other single location
that I know of. I like web strapping. I actually use web strapping for a normal
( as in weather) anchor rode. It will abrade and there is little material
compared to conventional line because it is flat and strong and doesn't have a
lot of mass. I would put chafe guard on webbing just like nylon or polyester or
what ever. The triple strand nylon will abrade quicker than braid. If I was
using all chain in a hurricane I would consider the webbing to attache to the
cleat. I would also use a length of nylon triple strand as a shock absorber,
and might even put a weight on the rode that would lay on the bottom near the
boat to give some "give" in the chain rode. If you have a steady 100 knot wind
gusting to 125 etc. the rode can get pretty tight and you need some play to
deal with wave action. That's my opinion.
