REMEMBER to use the lower eye when you moor your boat to a mooring buoy. Thus the boat will always keep in contact with the anchor. The upper eye is only intended for lift of buoy and double safeguarding. Do NOT use stainless steel together with galvanized iron, as it will start a galvanic corrosion, causing very quick breakdown / rusting through of the lower eye and the chain.
