A few of questions (for you to answer privately. No need to share your answers. Really.):
1. Is your anchor:
(a)
stainless steel
(b) galvanized
steel
2. Is your anchor shackle:
(a) stainless steel
(b) galvanized steel
3. Is your anchor swivel:
(a) stainless steel
(b) galvanized steel
(c) no swivel
4. Do you anchor:
(a) only for a few hours, rarely overnight
(b) no more than 24 hours at a time and I always wash the ground tackle with fresh
water
(c) for weeks at a time, sometimes more
5. Do your anchor in;
(a) shallow coastal/aerated
water, usually in sand
(b) mud that might be de-oxygenated and in sheltered locations in which the water is not aerated by wave action
(c) fresh water only
6. Are you considering tested, calibrated, and electropolished 318LN anchor chain from a factory such as Ketten Walder than gives a warranty on the chain and will, if you deliver the chain at your expense back to the factory before the warranty expires, inspect, test, re-calibrate and re-polish the chain:
(a) yes, of course
(b) yes, and I have a schedule and
budget for replacing the stainless steel chain at the end of its warranty
(c) no, I can only afford 316 chain or a lower grade that comes without
certification or a warranty
7. Have you read and considered Adrian Pringle's story of his experience with stainless steel anchor chain:
(a) yes, of course
(b) no, but thanks for attaching it to this post.
8. Zinc, which coats galvanised steel (by definition), is far enough apart from stainless steel in the galvanic chain that:
(a) a large amount of stainless steel that is in contact with a mass of galvanized steel, with both immersed in brackish or
salt water, will lead to the sacrifice of the zinc and
corrosion of the then exposed iron or steel
(b) nothing good comes of the combination of a larger amount of stainless steel electrically connected to a small amount of zinc
