The problems that I see with the rope and chafe protection is that it
has to be maintained and in severe conditions when a crew is likely to
be exhausted this may not be possible.

I have said it before and will say it again and again and again until people
listen. chafe protection on nylon is NOT wrapping a t-shirt around the line
and hoping for the best.

Proper chafe protection on nylon is at least one, better yet two, "safety" line
rolling hitching onto the nylon rode. the first safety line takes 100% of the
load until and unless it breaks and then the second safety line takes 100% of
the load until and unless it breaks at which time the nylon rode takes over.

IN ADDITION, *proper* safety lines are wormed (if three strand, not necessary
with braided line, which is better because is stretchs less back and forth
going through the chocks), parceled and served with Spectra fishing line. This
makes for one serious hard spot in the safety line where it goes through the
chock/edge/whatever. If you want belts-and-suspenders, you can also use
firehose over the hard spot, and even plastic tubing over the firehose and even
a t-shirt over the tubing if you want.

worming/parceling/serving has worked and worked well for centuries. It felt
out of favor of recreational sailors of late because it requires a sailor to
spend some time properly preparing a safety line ahead of time and most
recreational sailors are rather lazy, preferring early sundowners instead.

an all chain rode *will* pull your anchor loose (or break of the deck mount) in
a blow. Dragging anchor on all chain in a blow is NOT an act of god, but
rather an act of negligence on the part of the sailor.
