60 degree anchor swivel. Our stainless steel chain and anchor swivel shackle is precision cast and made from grade 17-4 PH stainless steel for maximum corrosion resistance and durability. It swivels 360 degrees and is equipped with a solid bronze thrust washer and a stainless steel screw pin. Multiple sizes are available to fit 1/4″ to 3/4″ chain.
To obtain maximum holding power of your anchor, the total anchor rode should be 4 to 7 times the depth of the water you will be anchoring in.
A good compromise between all-nylon or all-chain rode is a short length of chain (6′-30′) connected to the anchor, with a long length of three-strand nylon line connected to the chain. This combination satisfies nearly all requirements of a good anchor rode, except that it is not
abrasion resistant over its entire length. Long scope must be used to keep the pull on the anchor shank horizontal. Nylon is preferred for its elasticity. Its stretch reduces peak loads on the anchor and on your boat. The primary function of chain is to handle the chafe from rough bottoms that would otherwise abrade the soft nylon line. How much chain you should have in a chain-and-rope anchor rode is not fixed because of the variety of factors involved (boat displacement, draft, surface conditions, etc.)
In summary, at a fixed anchoring depth, the longer the rode, the less chain required. The shortest rodes are achieved with all chain, the heavier the better, but the penalty is increased weight and handling difficulty, and the slightly increased possibility of catastrophic failure if the chain stretches taut.
