Re: Maramu anchor and chain suggestions

Those are some interesting solutions that I have never heard of. Apparently a lot of thought has gone into how to deal with chain castles. I really appreciate your input on this. Did you read Toms simple solution in the next post that has worked for 20 years for him? I should have thought of that but it never occurred to me.
Yes, I understand what you are saying about how having more weight in the rode will provide more catenary at the same load, all true. Of course in higher winds even heavy chain will as you say begin to act like a rod so at that point having a really good snubber that won’t detach when the all chain rode is wanting to act like a rod is really important. That is another subject that I have been studying since I have had so many chain hooks pop off when conditions got rough and they were really needed. I have been tying my snubber to the chain in stronger conditions since the caribiner type hook that came with the boat does not look like it is strong enough for strong conditions but at least it never pops off the chain. The icicle hitch seems to be a little better than a rolling hitch to make this connection but I still worry about the line working free. I am open to suggestions. There is a lot to this anchoring business. (grin)
Assuming a proper snubber handles the surge loads, would the same weight of rode in 8mm or in 10mm provide the best holding? I think that if this was the only issue that the 8mm would be the clear winner due to the longer scope but of course it is never this simple. What options are there for instance to attach line to the 8mm that would be as strong as the grade 80 chain? And what about the strength of the shackle to the anchor at the other end? Those concerns bring me back to probably using the 3/8” chain. And of course in a tight anchorage with limited swinging room so that scope is limited, the heavier rode would be better I think.
You might check the math on the weight of the 10m of 8mm chain, unless I have made an error (quite possible) I think it is a bit over 16KG so about a 7 KG difference per 10m.
I have learned a lot from this discussion, thanks!
