Hi all,
I write periodically on ground tackle effectiveness and contributing factors. The attached article is one of those. As always, I invite questions and comments.

Hi Andrew,
Thanks: your comment is a good addition to the article.
3-strand does, indeed, cause the chain to wrap around the rolling hitch when loaded. This, however, I have never experienced as a problem as the wrap “un-twirls” itself when you transfer the load from the snubber to the chain when upping-anchor. When the rolling hitch gets to the bow, the wrap “nest” is gone, the load solely on the chain, and the knot is easy to get to and untie.
You cite problems dealing with the twisting to get the snubber released when under load. I am not sure why one would try to do so. Unload the snubber and the twist takes care of itself. I also suspect that undoing a rolling hitch under load is actually not possible, certainly not easy, and may be dangerous to fingers (same with other snubber-chain connections such as a chain hook).
That said, the twisting of chain and 3 strand snubber connection when loaded is unsightly and I suspect there is little functional difference between my 3 strand and your 8 plait.
What diameter 8 plait do you use?
My best, Dick Stevenson, s/v Alchemy
