I have the Furuno NavNet3D (2 MFDs, 4k radar), with RM AP and nav instruments. A friend recently installed the Simrad NSO.
Performance wise, the Simrad hands down wins. The NavNet3D is very slow to boot, once it's up and running it's tolerable. Might not be a fair comparison as I haven't played with the Furuno BB, it is suppose to have better performance. The Simrad is easier to change the configuration as most of it doesn't require a reboot like the Furuno.
IMO, Furuno has better chart choices, both C-Map
, whereas Simrad is Navionics
only (in addition to their own internal for US). Furuno also has both Maxsea
that integrates with NavNet3D.
Simrad is ahead in N2K integration, but that *should* be just a software
release for Furuno. Furuno has moved to a new release once a year, which can be aggravating waiting for a bug fix or new features. (I know of 2 bugs in the current
release that are annoying).
I don't think mixing chart plotter and AP brands is an issue. My Furuno drives my RM AP to it full capability and the RM gives stabilized heading to the Furuno (all over N2K). Obviously, mixing CP and radar is an issue.
If you care about what's under the hood
, Furuno NavNet3D is running on Windows CE (v5) and Simrad NSO is running Linux
Furuno is releasing a new touch screen
system, to be announced and the Miami boat show
in a couple of weeks. It could interesting (or not).
