garth, a blow is 20 knots with waves. Under those conditions, an all-chain
rode will jerk the anchor from the bottom unless the boat owner put out a LOT
of scope (more than a proper rode of some chain and a lot of nylon) and/or hung
50 or 100 pounds of dead weight in the middle of the rode.

chain don't stretch, and when the winds pull the chain more or less tight, wind
gusts can and do put HUGE loads on the anchor system, and jerking from wave
actions as put orders of magnitude more load on the system.

Like I said, NObody chains a boat to a dock or rock on shore. Why would anyone
think they can chain a boat to a rock under the water? ans: they don't think
so. they KNOW the anchor will drag. they are just too lazy to use anything
but all chain in their electric windlass.

20 knots is not "a blow", especially not if you are behind any kind of
protection in terms of where you are anchoring (e.g. behind a barrier
island, in some kind of protected waterway, etc.)

Those are reasonably stiff operational conditions around here, but are
definitely not "a blow".
