I have never used the anchor.I did use the rope once for a tow rope the first time my Yami bit the dust. If I can't find a dock or a can to tie up to, I don't go there.Had it on board to keep me off the rocks should both engines ralph. The way it looks now I am glad I never needed it. Most of the shallow bays one would anchor in around these parts will have a sandy or mud bottom and depth around 20'.Bill
In that kind of bottom these things work great, the harder the drag the deeper they go. Google "plough anchor"This is the one I have on the front of the 230
