I have to disagree, Chain Rode serves a very important purpose,
espially in Sandy or Muddy Sea Floors. The intent of the Chain is to
keep the Anchor set, of course this can also be done with Weights on
the Rode. This has been the salvation of any Boat that went to Sea in
a Hurricane and Moored, rather than have the Surge pile thier vessel
up on the shore with all the remnants of the Marina.

Sorry, but you are wrong. NObody chains a boat to a dock, and NObody chains a
boat to a rock onshore. The ONLY people who chain a boat to rock underwater do
so because they are too weak and too old to lift an anchor. An anchor chained
to a rock underwater WILL break out and/or break loose the deck chocks when the
wind picks up and the waves start. Everyone knows that but weak and lazy old
men.
