OK, I have a (recently purchased) 1985 46´6" Bertram Convertible. It has the standard instrumentation on the flybridge (see picture). I haven´t had the boat in the water yet but I suspect that at least some of the instrumentation is either nonfunctional or malfunctioning. As such, I had an idea: 2-3 color LCD type monitors. These would be used to present engine data (temperatures, pressures and various alarms), GPS, depth, fish finder, radar. I believe all this is possible today with NMEA 2000 technology. Basically I'm thinking of the equivalent of what in aviation terms it would be called "glass cockpit". A "glass helm" if you want. Am I crazy? Any ideas what I should be looking at? The boat has a Furuno open array antenna on the top of the half tower. It also has a Garmin GPS antenna there. In addition, there are 2 transducers in the bottom of the hull. Everything else (screens etc) is missing. Current condition of existing equipment is unknown. The boxes hanging on top are empty save for a VHF radio. How should I proceed with doing my homework on this? Are there any displays that are just displays (i.e. no built-in GPS, maps etc)?
