I would say that with the exception of an occasional manual windless
they are all equipped with electric anchor windless and probably 90%+
are using all chain rode and fairly heavy anchors. My own 40 ft sloop
displaces about 13 tons and has 45 lb. and 60 lb. CQR anchors and 200
ft. of 5/16 inch chain. If I were making off shore voyages I would
carry an additional 100 mtrs of 1 inch nylon rode for a total of 528
feet. Probably fairly typical of the anchoring equipment you see here.

Just for information (and I don't recommend it) I did make a trip down
to Malaysia and back with an inoperative anchor windless and hauled
the anchor once a day by hand, for six days.

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.
