Anchor rode markers
Bob;3 strand twist is the best anchor line for your location, with about 20 feet of chain (I prefer hi tensile chain). I considered marking the rode every 30 feet, as recommended, but decided to use the low tech method. Outstreatched arms measure about 6 feet. Flake out 6 foot lengths on the deck to achieve the 7 to 1 ratio necessary for safe anchoring. Add another length or two for good measure. Close enough for me.PAT
