I found WM brand three strand docklines in the dumpster in Seattle that was too soft/supple for the marina I was in (the braid easily collected splinters from the dock and deposited them into the users hand). Would have been terrible had I intended to stay in the marina. A few years of UV and the nylon got stiffer and no longer picked up said splinters. I used one of those docklines as a snubber for all of our anchoring.
Procedure went something like this:
-Let out chain to the scope required for the conditions.
-cleat off one end of the dock line or throw the spliced end over the cleat
-fish dock line out through the fair lead and over bow roller
-tie rolling hitch onto chain
-let chain out until snubber goes tight and chain has plenty of slack
-pin chain to anchor roller in case of snubber failure
I normally use the stbd fair lead for this task and have not noticed the boat sailing back and forth at anchor very much, so I suspect having two sides to the snubber on boats of our size isn't really needed.
That same dock line has been going as our snubber since 2017. I dubbed it "snubby". I did have to whip the end of the line to preven the braid from unravelling. I think maybe once? I had to cut the last 8" off and whip it again when the line started to look rough. I believe the lie is 10-12' long.
A friend gave us a proper snubber off his Cape Dory 30 here in NZ, which was a chain hook on the end of a bridle. It managed to come unhooked from our chain a few times while in use. I went back to snubby and gave it away.
We rarely see winds over 25kn at anchor so I can't comment on how it would hold in a storm, but the shock absorbance of snubby is fantastic. That one piece of line is still going 7 years later....
Hearing it stretch and ease in the night from just below in the v-berth let us sleep well - we knew the anchor was still set without having to get out of the bunk to look.
I often see all sorts of fancy gizmos/gadgets being sold at the local chandleries that can easily be replaced by a simple knot in some cordage. Rolling hitches grab chain very well, I have never had it slip. They are also very easy to untie when the time comes.
