To settle an argument, I am looking for an all chain rode anchoring scope
table. Chapman's nor the Coast Guard Auxiliary Seamanship manual has
anything on all chain rode scope. I need something in black and white.

Ralph,

I use the same scope as with rope. It is certainly safe to do that. It's
true that scope is related to angle of pull on the anchor, but in extreme
conditions both chain and rope could get bar-tight and would have no
cantenary.

One other "angle." If you art in the habit of backing down on your anchor (I
am) short scope would likely pull it out instead of burying. Most of my
experience in Long Island and the Chesapeake is with sand and mud only.

Ralph, that may depend on the anchor. I am using a SuperMax right now in
Nantucket harbor at the manufacturer's recommended 7:1. Working well in 20k
with gusts to 30k. 5:1 works okay for me most of the time, but the SuperMax
guy (Andy (601) 442-1630) says not to trust it when the wind picks up.

There may not be a correct-for-any-anchor chain scope table...

Hope it calms down tomorrow...I need to start heading home.
