Does anyone out there have a feel as to how long a servicable lifetime one can expect for a commercially manufactured concrete mooring anchor if kept in salt water for the full year (not removed in the winter and reset in spring). The style of concrete anchor does not have a metal bar embedded that can corrode but instead has a PVC tube that goes through the body of the concrete that a chain (that can be replaced) goes through the PVC to which the heavy chain rode is attached. Does concrete itself degrade or weaken when constantly submerged in salt water?
