I have used many styles and have gone to 2 different ones and they hold my boat rock solid.
I have 1 Richtor anchor and the newest edition is the Digger anchor. The Digger is an awesone anchor and between the 2 of them, I can hold in about any current.
The Richtor I have 3′ of chain on and 150ft of rope. The digger has approx 125ft of rope also.
I do not typically use that much rope unless it is really bad. I do not like all of the rope out when a biggie is on as they can get into the rope.
