The downside of
course is you really need to maintain a nylon rode under such
conditions...rigging chaff protection or letting out small increments to
minimize chaff.

nylon rode in heavy weather conditions should have "safety" lines attached to
take the chafe, sometime two safety lines. A safety line takes 100% of the
chafe load until it gives up (if it should give up) at which point the second
safety line takes 100% of the chafe load, etc. safety lines are rolling
hitched onto the nylon (or chain ****IF**** the safety line is
looooooooooooooooooooooooooooooooooooooooooooooooo oooooooooooooooooooooooo
ooooooooooooooooooooooong enough to give shock attenuation to the chain, i.e.
safety line lengths of 50 to 100 feet), the first safety line tight, with the
second line loose as a back up in case the first safety line gives up, the
anchor rode loose upline from the safety line(s).

A proper safety line will be wormed (if twisted line), parceled and served with
Spectra line (Spectra fishing line is a good source) to form a serious hard
spot where the safety line goes through the chock.
