I have 2 rolls of 1/4" 600ft rope. I buy it at
Harbor Freight. I buy
Chain from there too. I used to use 5/16 x 20ft Truckers chain cut in half but I'd probably get that 1/4" x 35ft in the bucket and cut it in half now. It's new and buckets are always handy.
For the best results use anchors designed for the next bigger size of boat than yours. The people who designed the anchors had no idea that we would try to anchor in 160ft deep water in a gail force wind that's whipping around in all directions.
We use cord reels for extension cord to keep the rope organized. All 600ft of the rope will fit (just barely) on a 150ft cord reel. I like the Home Depot ones better than Harbor Freight's.
