I am considering installing an electrical access plate sold from rigrite to gain access to my wiring just above my mast step on my 30+. The reason for this is because I am not getting power to my foredeck light. I have power to the light inside the boat prior to exiting to the mast step. I am trying to avoid taking down my mast with all the costs and time involved. Has anyone else installed such an inspection cover? It is not a large cover so it needs to be installed where the wires would be best accessed. Would this degrade the integrity of the mast?
