I would suggest that your proposed 1" rode would be somewhat of an
overkill.
Although the possibility of chafe is a factor the breaking strain of your
5/16 chain is about 3 tons, while the breaking strain of 1" dia nylon is
about 10 tons. Certainly you must consider safety factors and the question
of chafe on the nylon but I would suggest 14mm nylon instead , which would
allow you to stow a longer length of it.

It probably is overkill. On the other hand I got it cheap. A chap
ordered a spool of 1 inch and after it arrived decided that he really
didn't need all that rope so gave me 100 M. It fitted, carefully
packed, in one locker under the vee birth; I spliced a thimble in the
end and decided that it was an emergency mooring/anchor line.


Yes, can't argue with that!
