On my next boat I'm going to about 50 - 100 ft. of chain and a nylon

to rig a snubber every night.

You're in coral country aren't you? Coral sand erodes nylon and coral
cuts it. My take on this is that in light winds when the chain is
lying on the bottom you want the nylon well above the level of any
bommies that might be around and still want enough scope out to be
safe. I've been using 35m (~114') of 10mm (~3/8) chain and wouldn't
go with much less. Indeed, I just replaced that with 150' of
nominally 5/16 (actually 9mm) G43. Rigging a snubber is pretty easy
work.
