Do you mean where the ski pylon inserts into the flooring on models that have it? If so, I have not heard of one that is made for it. Perhaps someone could fabricate one though. For those that want flags on the back of their boats, normally I hear of them either adding on the OEM version, or they do some sort of fishing rod holder and secure it in some way to the rear of the boat.I have a 2018 RSB. Do they make a flag pole that inserts into the ski pole? If so, where can I order this?
