I am looking for suggestions on where and how to mount a Raymarine A65. I have a 1993 Oceanus 400. There seems to be no space large enough on the console to mount it. I am looking at the various navpos housing units for the job. I have not seen a suitable stainless steel mounting stanchion for the job. The area just over the switch panel is curved and I have seen no stanchion bases of thet shape. Any help, or suggestions appreciated.
