I hope this is helpful.
Very helpful, thank you. I would not have dreamed of considering a synthetic line for the keel cable, I thought stainless was "de rigueur" for that purpose.
found that the chain I originally used for mooring my floating docks in a fresh water lake were eaten up in a few years, but after switching to nylon or poly (forget which) lines they have lasted a decade.
I'm sorry to say I avoid facebook, don't care to publish my personal info worldwide and am concerned about the many security breaches there.
