- Flake out the chain in even loops. In this case, 10-foot lengths fit across the tramp.
- Pick marking points and temporarily mark with tape. I chose 25, 50, 75, and 100 feet.
- Collect a box from the dumpster, notch it as needed, and paint away. Plain-old Rustoleum or anything similar will hold-up for years; it chips going through the windlass but remains visible.
- Just leave the box on-deck until your next visit, to make sure it's dry. No rush.
My 100-foot mark is long because I like to keep the splice off the windlass. It passes fine, but the windlass doesn't grip rope well, so hand tensioning is required.
PS. Not my original idea. I saw it posted somewhere, tried it this past weekend, and deemed it worth sharing. Good boat keeping common sense tip.
