Yes and no...
I've spent quite a lot of time on this issue, and finally settled on Blue Sea Systems. The reason is as much availability of components and support from the manufacturer as it is utility. I looked at Marinetics and Bass as well, and, of course, evaluated them in terms of the original OEM panel. First, let me state in no uncertain terms that the original OEM panel on my 1984 Catalina 36, which I think was made by Seaward (not sure) is a piece of junk; a fire waiting to happen. In fact, there was a burnt switch on mine which didn't work, and the fuse was still O.K. - though I don't know the history before I got the boat. The panel has no buss bars of any kind, uses daisy-chained spade connectors to distribute power and ground, and has the fuse holders and switches hot-glued to the back of the panel. The wire is not marine grade. The new panels I've look at are much, much better, but they all have some annoying functional characteristics. One that stands out is the extreme inconvenience of changing a circuit breaker once the panel is all populated and wired; on the BSS panels, it requires removing either all of the breaker mounting screws, or removing the positive bus from all the breakers. Not something you want to face in an emergency or heavy seas. Probably should not be done "hot." Also, some relatively cheap-to-make and necessary components are sold as overpriced accessories, such as the rear safety cover for the BSS AC panel - a vacum molded piece for $18.00, as I recall. That said, in the U.S. I'd recommend BSS as having the most complete system, available in many retail outlets, with good value and great amnufacturer support. See link. jvp.s. if there's interest, I'll post pics of my complete electrical distribution system upgrade.
