Cobra Grey

Good Day Everyone, New to the Thread. Bought my Bass Raider a few weeks ago, been out three times and love it. Installed a Fish Finder, Rod Holders, Cleats, etc using rubber tight rivets, the type for Kayaks, it seems to be working well. I decided to start that way and if need be I can replace them will well nuts later if need be. I heard a few people talking about putting a carpet/plywood floor in, I was going to do this, but then my wife took me to Lowes, suggested I use the foam padding that is used for workout equipment. I bought a set, trimmed it, had it installed in all of 10 minutes. I love it, just pick it out and wash up is a breeze and it cost me $20. It is comfortable and sturdy standing on it, and has some good traction. Used the clippings to cover my Dolly setup. I also wanted to know if anyone has installed a drain plug behind the Battery, in that flat area. seems like the place for it. mine collects a little water there over the day of fishing. not an issue, but don't really want to empty boat of my gear and turn it over before hauling it home. any suggestions?
