Very interesting replies. So, if you are not supposed to haul your boat up to the anchor with your windlass and you are supposed to snub your rode when anchored, then your tonnage should only influence rode size and grade, right? My ground tackle is a 20 kg. Bruce claw and 150 ft. Of 5/16 BBB chain. I rarely anchor in depths beyond 20 ft unless there is any emergency. For 20 ft. I lay out about 60 to 70 feet of chain.
