I was out for a short boat ride. The GF had her daughter and friend out so thought we would just go run around the lake and bay. The music was on and then suddenly died.....I thought the Bluetooth had lost connection....nope...radio was dead. Oh wait...chartplotter...dead...all radios...dead. EVERYTHING on the flybridge....DEAD!!!! Engine instruments were the only thing working.
On my boat there are actually 3 different DC panels. The panel with the big breakers(and also the "hot items" like bilge pumps) is under the companionway stairs. On that panel is a breaker labeled "Flybridge". That provides power to another DC panel on the flybridge where all of my electrical appliances on the flybridge are powered from. Yep you guessed it. The actual breaker fried. It was a 60amp breaker and I have a pretty big stereo up there. Maybe the age and the stress I put on it caused it to cook.
Anyway, my point here is we always aim for redundancy. One breaker that provides power to ALL navigational instruments is not that redundant. It was a nice sunny day so it was really of no consequence. But that one failure caused all of my "redundancy" to go out the window....not redundant at all.
So while one may think they have backups, You may not. If they are all running off of the same bus, not redundant at all!!!! Had I been in a busy channel in the fog, I would have been fooked!! My only back up at that point would be to navigate via app on my phone. There is a high likelihood I would have survived, but it would have definitely upped the pucker factor.
