I added a couple of bolt-on's to my factory launchers and they worked out well, then I added (3) across the transom. along with the (6) boat rod holders, I troll 15 rods with the use of planner boards in the spring, not bad for a 25' boat. Also I did not like the gold launchers that came with the boat so I used easy off oven cleaner to remove the old gold anodizing and then polished up the bare aluminum. They hold up pretty good, I took pictures 1 &2 last night and I have not polished them since spring
