Thanks for the link Gene, by the way, I missed that the first time
around.

don't thank him, Tom. The site is like a Texan fraud. "Big hat, no cattle."

While the site uses a lot of math symbols, it is the work of someone who
understands damned little about catenaries AND thinks boats anchor in lite
winds always.

if you wish to anchor on mostly or all chain in a blow, you MUST hang LARGE
weights (plural) in the middle of the rode. otherwise, the forces on the
anchor and deck chocks get huge very quickly as the chain goes tight, and you
will break loose (which is not an Act of God, but rather the consequence of an
act of neglegence).
