Wow! There is definitely some strength in those snubbers! I have no doubt you've never broken one. I think the breaking strength of that rope is around 47K pounds. You could pretty much hang your entire boat off of one.
But as the Spade article says, make sure that you are using line that is sized to give you enough elasticity. That is the key. A 47K# snubber is going to transfer most all that load to the chain anyway, which will be FAR weaker. How do you attach the snubbers to the chain? That can have a negative impact as well.
BTW - how long was your trip? I assume your write up of it is in your blog link?
I forget what the working strength is, but it wasn’t 47K … I doubt if my standing rigging is that strong, let alone my chain. All I can tell you is they’re stretchy, but damn strong. I don’t want the snubbers to be the weak point in the system, after all. But they definitely take the shock load well.
We took about 60 days to go from Lake Ontario to Newfoundland. Most people do it in less than 1/2 that time. But trust me, my tag line is not simply aspirational. I live it
BTW, we only saw two docks the whole time. Anchored out the rest of the time, sometimes in rather tenuous locations.
Mark, your comment about shallow water and no catenary is true. At that point though, it is the friction of the chain on the bottom that provides the shock absorption and gentle loading. This is assuming you’ve got out the appropriate rode length (at least 5:1, and I usually go for more).
I like anchoring in shallow water b/c I prefer being close to shore. We draw 6’ so I’m fine with 8’ at low tide if seas are no issue, and as long as I can get a good set. Below 8’ I get nervous.
ADD: I’m not trying to argue everyone should be on all-chain. Rope/chain is clearly a fine choice, and is the best choice for some boats and/or some anchoring conditions. It was the best choice for my previous boat: a 34’ cruiser.
My experience has taught be all-chain is best for the widest possible range of conditions, but only IF
your boat can reasonably manage the weight and the retrival. If it can’t, then it’s not the best choice.
