Networked Systems:

Furuno Vs. Raymarine

Electronics

Raymarine and Furuno are the only manufacturers offering completely

networked electronics packages. PBR takes a look at both, focusing on

user interface and screen viewability.

ngines—diesel or gas? Wind-

lass—yes or no? Genset—how

many kilowatts? These are the

options you normally have to choose

from when buying a new boat. Now

add this to the list: Electronics pack-

age—Networked? Integrated?

Standalone? Lots of marine electron-

ics manufacturers offer standalone

components like a radar, chartplotters

and sounders. In the past, standalone

units were the only way to go. Nowa-

days, integrated units with all three

are available from several manufac-

tures, including SI-TEX and Simrad.

But to take things to the highest level,

to what is today the state of the art,

you’ll need a networked system. That’s

where we cast our eyes for this re-

view. Only two major players in the

marine electronics world are in the

networking arena today. Furuno has

its NavNet system and Raymarine of-

fers HSB².

Integrated systems like those by SI-

TEX and Simrad—as well as both in-

tegrated and networked systems by

Furuno and Raymarine—all have the

ability to display multiple data

sources, like radar, chartplotter, GPS/

WAAS, and sounder data on a single

screen. This is a real advantage for

the small boat owner. Especially if you

desire a full range of electronics but

lack enough panel space for

standalone systems. Even if you’ve got

the space, the connectivity of inte-

grated and networked systems allows

them to do things independent com-

ponent systems are not capable of. For

instance, most integrated and net-

worked systems have the ability to

overlay radar returns on top of the

chartplotter display so you can see

and use both simultaneously. Try that

with a standalone system.

So what’s the difference between

integrated and networked? Net-

worked systems go one step further.

They can interconnect and use mul-

tiple display units. Plus, and this is

the big one, a networked system

equipped with multiple display units

can control all functions from any

single display. What that means is if

you have a networked system in-

stalled at the helm with radar,

chartplotting, and sounder capabil-

ity you could have another single

display anywhere on the boat and

not only see all the data but control

the functions of each, as well. That’s

quite impressive to us and nearly ap-

proaches the capabilities of the Starship

Enterprise.

What We Looked At

Even small seven-inch LCD displays

used by Furuno’s NavNet or

Raymarine’s HSB² networking systems

seem big. Their ten-inch LCD displays

are huge. Bigger screens are available

but we’ll stick to 7’s and 10’s.

Raymarine does have a couple CRT

radar systems that are HSB² equipped,

but we did not research or look at them.

Both Furuno and Raymarine build

integrated systems, like chartplotter/

sounder combos, or radar/chartplotter

combos, using the same screens as

their NavNet and HSB² packages. But

Above: The Furuno NavNet’s alphanumeric keypad, which allows easy data

entry, is one of its strongest features. Notice the trackball, which should be

removed and cleaned periodically (just like a computer’s mouse ball).
