For years plying the waters of our Great Lakes took skill and relied solely on
paper charts and the crackle of the ole marine radio! Nothing was more stressful
than plotting a dead reckoning on a raster chart during a 30 knot wind pushing
you closer to the rocks that you were trying to avoid in the first place!
Today, we enjoy and rely on electronic devices to solve our navigational and
communication problems. Take the new version of the maritime VHF radio! It
allows us to communicate our safety concerns within a third of a second for all
stations to hear. We can communicate with each other for a multitude of
reasons. We rely on radar, marine GPS Chartplotters and weather maps in one or
more marine devices.
Prices and competitive retail advantages have allowed all boaters the opportunity to own and enjoy all of these simple electronic pleasures. NMEA 2000 now makes hooking up all these devices a breeze. NMEA 2000 combines electrical and data specifications to set up a marine data network for communication between marine electronic devices such as radar, depth gauges, GPS – nautical chartplotters, navigation instruments, engine gauges, multiple tank level sensors and laptops. It has been defined by, and is controlled by,
the US based National Marine Electronics Association (NMEA). More and more
electronic manufactures are making their products to this standard.
Next time you are in the store looking for a new addition to your boat’s marine
electronics package, look for the label NMEA 2000 compliant. NMEA 2000 makes it easier to install, reduces costs and allows boaters to mix electronic manufacturers so they can enjoy the best equipment on the market. The NMEA 2000 system is based on a single backbone cable that sends messages and data in both directions.
The above drawing illustrates how a NMEA 2000 backbone can connect a power boats’
electronic device such as a GPS, VHF, compass, engine data, navigation system,
I know what I’m doing in the Spring! My Carver’s electronic devices need an
upgrade and there is no better way to do it. Come in and see us to discuss your
NMEA networking needs.
