In the book I bought about anchors and line handling it mentioned an "up to 33% improvement" of holding power in soft bottoms by using a wire rope between the anchor and the chain. Apparently the wire rope doesn't create as much resistance and the anchor buries itself deeper into a soft bottom.
The question I have is, how do I put a wire rope on the anchor? I've heard of wire splicing, but am unsure if this is safe in this application. It would need to have a WLL of better than 5,000lbs to match the rest of my ground tackle. Using this webpage ( Wire Rope
) I have surmised that 5/8" 7x19 with Flemish splices should
be more than strong enough.
The length of the rope would be determined by the distance between the end of the anchor and my windlass when the anchor is raised. I would splice around a thimble for added abrasion resistance. There would be an anchor swivel between the wire rope and the chain.
