When we cruised for 20 yrs in the pacific northwest we carried 50' of chain. Rope is stretchy for keeping shock loads from the anchor in a big blow when chain cantinary goes away. My reason for chain now is concern over chafe on underwater coral etc that was not an issue in PNW. I use a snubber now but with short chain the snubber is built in. Just my highly biased opinion!
