Fantasy fjord
C'mon guys, get real! You're not going to anchor in 850 feet of water--that much rhode would fill up the whole bow berth of your boat, and the chain would sink it...Chene anchors belong to a class of anchors that are favored by fresh-water fishermen in inland lakes. The chief design features the manufacturers are aiming for is ease of removal; the boats they are used on tend to be small and without windlasses, and the fishermen need to anchor and then move frequently as part of the fishing activity. A large Chene may be strong enough for a large sailboat, but since it's designed for easy removal that may not be what you want to use to keep a larger boat from dragging overnight. Use anchors for their intended purpose and you won't get into too much trouble.
