I have a Danforth that I use on my 27 ft regal. #14 and about 5 or 6 ft of coated chain. I gave 100 ft of rope that I alway use all of unless at the beach. Most of the time I can't pull it out. I have the tie it to the cleat and power it out with the boat then drag it behind to clean it cause it always brings alot of mud up with it.

The only time I have had any trouble with it holding is on rocky bottom, which is given, it's ment to dig in, can't dig into rock.
