Looks good. I went a different (cheaper) way. I bought Scotty 1101 downriggers that have a swivel base included and mounted the base behind my back track...really close to where your rigger is in your picture. All I have to do is take out four mounting bolts and remove the downrigger when not needed. The fishmaster already has a backing board under the gunnel but I added a stainless steel plate under the board and it seems really solid. No problem to reach it from the back of the boat and the swivel is approximately 4 inches high already but when removed a plastic base is all that is left and is about 5/8 inches thick and isn't in the way. Saved buying the piece of track and also the base pictured below. Approximately a $100.00 a rigger.
