The swivel rod holders that I am familiar with are heavy duty and the swivel tension is adjustable. You would want the mount to be very solid and the rod holder to be removable without a lot of hassle so that you can adjust them if needed. If your gunnel is not cored then I would try to find the best way to glue some coring on the underside where the rod holder will be mounted. If the only way is through the round hole in the top of the gunnel that could be tough, like playing operation with strips of coring and epoxy putty. Maybe not a workable plan! You might also consider a small round access plate below it on the inside liner to get to everything. If you put it near the bottom of the swivel cup then you could caulk everything in and still reach the swivel without removing the holder.
Good luck!
