Hope this helps
Andy, the bolt heads that hold the handrail on are covered with teak plugs. These must be reamed out using a drill bit to expose the head. Now, on my 25, down below in the plastic headliner are plastic caps that are friction fit inside the rail bolt hole. Carefully pry these off using a thin knife to expose the recessed nut. Having someone below pinching the nut with long needle nose pliers, unscrew the bolts. You can buy replacement teak plugs at your local chandlery. These are glued, and banged home and sanded back to the rail height. Obviously, I have made some big assumptions that our boats have similar rail mounts??? Don
