Steelhd101 it really depends on what type of anchor you have (ex) is it a pyrimad anchor because I also had the same problem (with that type of anchor), I actually built a new 45Lb anchor with flat bar welded on the bottom sticking out from the sides about 5" this works well. They also sell anchors simlar that work just as well if not better. I might also add that the more anchor line you let out the better you will hold, you might know this already though.

just some advice
