Fwiw rocnas will set upside down, not really well but it can happen. We are going on ten years with ours and have never had any reset issues. Dragging has been due to bottom, fouling or not doing a hard set. In ten years and probably 2500 uses this has happened three times, all in the first year of use. Getting ready to buy our third chain this fall. We are still quite happy with the anchor choice.
