I use a Cumberland Crappie double seat base. I t also has the arms for attaching your rod holders, umbrella, etc. I like that it fits in the boats pedestal base and everything can be removed and transferred to another boat if you want to do so. It does have a tendency to shake your rods if you step on one of the rod holder arms, but at least you are not drilling holes all in the boat. These will also go to the back deck if you want to use the rod holders back there for trolling- or "pulling cranks" as it is now being called !!
