Vessel: LOA 39' 0" (22,000lbs)
I have about 125 ft of 5/16 galvanized G4 chain and 150 ft of 3-strand 5/8 line and a 44lb anchor. I anchor in between 8 - 20 feet of water. Average is typically 10-12 feet. The line has never been in the water.
The benefit of an oversized anchor and an all chain rode is I can anchor around 4:1 - 5:1 with no issues. We regularly ride out blows of 20-25 mph winds at 5:1 with a sand or sand/clay bottom with no issues. Over 30mph winds I tend to not sleep well, then laugh when the anchor is so buried the windlass struggles to break it free from the seabed.
