Anchoring in deep water is a very effective way of positioning your boat over a bottom structure that holds fish.
However, if you are anchoring in more than 100 feet of water you may have to make a few modifications in your regular anchoring gear.
Most folks have a regular fluke-type anchor, several feet of chain and enough rode to play out for inshore waters. The Coast Guard recommends a ratio of 7:1 when anchoring to give close to 100 percent holding power. This is good advice when anchoring in for the night and you want to be sure your anchor will hold when you are sleeping.
This ratio would mean that if we were anchoring in 200 feet of water we would need 1,400 feet of line. In a small 23-foot boat like mine, I would have to bring along a row boat just to hold the line. For fishing you can cheat a lot and shorten the scope.
