You don't necessarily need $$$$ so much as planned redundancy. Multiple antenna
, multiple display units (multiple E80's or E120's say), etc. Its a marine environment
, things *WILL* get tossed around. Brands don't matter if something goes flying into the LCD display despite your best effort to secure things. Using recreational vs commercial equipment
can be just fine if you keep this in mind.
If you are sailing in commercial
lanes or any congested area I'd be sure to get AIS
as well as the standard instruments people put in. I put a Multi display in the aft cabin
near my berth so I could check wind
speed, position, and other items without leaving my rack. I can also redirect any display from my E80s to multiple flat screen
TVs on the boat or redirect my notebook PC display (with its internet
connection to lots of weather
and doppler radar sites) to my E80 displays.
Integration is the key, but redundancy makes it safe. FWIW
