Combination stainless steel chain/ galvanized steel anchor
Grigoris, glad to hear you are "coming along for the ride" aboard WHOOSH. Thanks for the kind comments.
After seeing this thread, I returned to the boat and was handed a copy of last month´s PBO (British DYI-type sailing mag), wherein this topic was being discussed. The pic showing a stainless shackle going thru the galvanized rode´s first link told quite a story; that link wasn''t going to last long. Clearly, cathodic activity was present...and if it was happening with the galvanized chain link, one is left wondering about the stainless shackle.
Given the reverse, it´s hard to imagine why one would trust the last link in a stainless rode when connected to a galvanized shackle. The lifespans offered in the PBO article - for a galvanized shackle in "normal use" '' were 10 years when connected to galvanized chain and <1 year when used with stainless.
