Reliability Word Of Mouth Relative
I think it's important to remember a couple of things. First, Raymarine in its earlier iteration was one of the early volume adopters of large LED displays, networked data and smart autopilots. As such, there will simply be some early failures too. The upside is that the get it right by learning as the technology matures. Second, they are either the largest in the market, or among them. So, you will have more total failures. Third, I believe most of the US production boats have them as the default factory or dealer electronics, so you will read more on these boards about them. Having said all that, I am in no position to say definitively which is better build quality based upon any objective data. I have used them for some thirteen years now in their Autohelm, Raytheon, and Raymarine iterations and have found them generally reliable and the factory support superb. Were I to buy a new boat today, I would select them again because of my comfort level with them. I did buy a Furuno radar, but that was a preference of user interface and not about reliability. I do have an RC520 chartplotter in the nav station that I am satisfied with. It also will display the instrument data which can be handy at times.Rick D.
