We use colored zip ties (like many others do) at each 25ft interval.
Use the large ones about 12in we place 3 to mark each 25ft interval don't clip them leave them full size. They pass thru the windlass easily and position each one so that they stick out at 120 deg to each other on the chain or rode as they pass thru the windlass one will be sticking up or two and you can see it easy at night with a flash light, they are cheap and replacing them is very easy
