Like I said, I used it like that for 20 years...really...so does the rest of the people I knw, and if we had trouble, I would have known about it.
Very very few boats here drag. The latest was a power yacht, in 2004 with one of those fancy stainless things that look like a manta ray. Destryed in a cove.
Look, I use the anchor to hold my boat, you use it to make a living...we can't argue, can we?? (VBG)!!
