I have two questions. First, on my O'Day 25, I want to add jacklines. I am thinking of the webbing type that runs the length of the boat along the deck and near the stanchions. Does anybody have any suggestions as to attachment points, webbing type/size or other suggestions?Secondly, my older parents had a difficulty in getting under the lifelines when getting in and out of the boat from the dock. I've seen stainless steel hooks that allow the steel lifelines to be unhooked. Is this easy to add? How does it affect the integrity of the lifelines?Thanks,sPk
