Rick....I bought a 25' dog cable at home depot that is coated in a red plastic and has a HEAVY eye on each end that allows for it to be locked (some people apparently chain/cable their dogs to the ground?) It worked GREAT and allowed me to run the cable through the handle on the motor and other parts of the dinghy when on the dock or davits. I have used that same cable for the past two years with no show of corrosion.
