I didn't see this in time, but I run track systems on all my boats. There are a bunch of manufacturers, Cannon, Bert's, TraxTec to name a few. All the rod holders, downrigger mounts, ect from all brands that I know of will fit in each other's tracks. I normally fish walleyes around home so I keep RAM bases in the tracks most of the time, but when I want to go salmon fishing, I just slide in my Bert's tube holders, downriggers, and rod trees. Or if the kids want to swim, just take everything off and put it in a storage locker.
Ignore the water in the first pic, had a livewell pump pop out, but you can see the tracks and RAM holder bases. The second pic is my salmon boat with some of the accessories mounted.
