Thank you all for the replies and PATIENCE. I just now read the posts on anchoring previous to my post and saw sentinals covered pretty thoroughly. My conclusions-- get a plow, a
Danforth, and a Grapnel-- stick one of them it on 50 - 60 feet of 1/4 inch chain at the end of 300 feet of 5/8ths nylon
anchor rode. This , in my opinion , would handle just about any anchoring situation where I want to sail in the Great Lakes. The Grapnel would be best in rock right ?
