I bought the anchor when I had my last boat. I had watched a friend anchor with one in the Virgin Islands and liked what I saw. I was diving as he dropped the anchor and it set beautifully and quickly. So when I returned to the states I bought one. After one summer's use I was disappointed. I had dragged with it in a couple of places I never expected to drag. I had it on 3 fathoms of 3/8" HT chain and 15 fathoms of 5/8" braided line. I sold it the following summer.
I will not have another on our boat! Barnacle Anchor Grade F
