If I'm using incorrect terminology please educate me. Anywho. When I bought my boat the previous owner had removed the sidelines? lifelines? The lines that run along the edge of the boat and hopefully the kid from falling over. The line and the posts that hold them had all been removed and stowed inside the boat. Today while cleaning the interior I came across what I believe are the screws originally used to fix the posts to the deck. When I attempted to test fit one of the screw I found that there is simply a hole in the fiberglass deck and nothing for it to screw into. What is the proper method for re-installing these?
