Garmin has proposed a sleek, modern marine electronics suite for the new Kadey-Krogen 55′ Expedition that offers extensive capability and nearly unlimited flexibility and redundancy due to its extremely high level of NMEA 2000 networking integration.  NMEA 2000 has been a long time in coming and the electronics suite proposed by Garmin fully embraces it.  New Krogen 55′ Expedition owners will find redundancy and nearly unlimited configuration capability in this system.  Garmin’s proposal was developed by its in-house team of systems designers and transmitted by Greg DeVries, Director, Marine and Recreational Sales.

DeVries and his colleagues responded specifically to our hypothetical buyers’ Request For Proposal, which outlined how they plan to use the boat and the general capabilities they would like to have from their marine electronics aboard.  Kadey-Krogen does not have an exclusive arrangement with any marine electronics supplier, so its owners can examine the offerings from all suppliers. Our fictional couple intends to cruise extensively in coastal regions but may also consider a transatlantic voyage at some time in the not-too-distant future.  You can take a look at the complete Garmin package — the Response to the RFP, as well as a portable document file that includes an extremely detailed schematic of the electronics suite.  Here’s an overview.


Garmin says:

“The Kadey-Krogen 55′ Expedition Yacht is a world-class passagemaker that will require advanced marine electronics and ship systems capable of permitting long distance cruising in a safe, easy and comfortable manner for all on board. As a leading electronics manufacturer, Garmin has a strong global support presence and a service network of dealers and product support teams that are able to provide new sales, replacement units, field service and support to any location the boat may travel, should the boat encounter a problem or need to add more equipment.”

Garmin marine electronics may not yet be as ubiquitous as Raymarine and Furuno, but Garmin GPS units — of all kinds — are not only everywhere on the planet but they come from the same company as the marine electronics.  So if you can find an authorized Garmin dealer in whatever corner of the planet you find yourself, you can probably get a Garmin replacement part as easily as a handheld GPS.

Garmin feels that a critical design philosophy for the Krogen 55′ Expedition outfitting is redundancy.  Here is DeVries and his team on that topic:

Long range cruising and transatlantic voyages for which the Kadey-Krogen 55′ is intended, add an important and required additional level of equipment for redundancy, safety and comfort. Based on the vessels planned use, we have added duplicate pieces of critical navigational and communication equipment to its overall suite of marine electronics. This includes installing a second radar, autopilot, and full function wired VHF fist microphones. This added equipment is to meet the long range and transatlantic requirements, and does not have any direct relationship to the equipments service lifecycle, duty or reliability.


The Garmin proposal is centered around its one year-old 4000 and 5000 series Multifunction Display chartplotters.  They are similar in capability, but the 5000 series features a fast touch-screen interface.  Garmin suggests the 5000 series, which is fully networkable, for the new Krogen 55′.  It’s available in screen sizes from 8 to 15 inches and Garmin proposes two of the 15-inch displays for the new helm.  Cruisers on a tighter budget could go with the less-expensive 4000 series, which sport a more traditional pushbutton interface.

The Garmin 5000 series MFDs have three Garmin marine network Ethernet-type ports and one NMEA 2000 5-pin micro-sized port on the back.  The inclusion of the NMEA 2000 port means the system can not only talk with other units from Garmin but also easily connect to a NMEA 2000 backbone, on which there can be an almost unlimited number of addition devices and sensors.  The fact that both Garmin network and NMEA 2000 can be connected at the same time represents the height of convenience and flexibility.  Each of the MFDs comes with its own dedicated GPS antenna as part of the purchase price.  Garmin says the GPS 17X NMEA 2000 WAAS-enabled, high-sensitivity antennas can be installed “above or to the underside of decks and fly bridges.”

So the two big 15-inch MFDs are side-by-side on the main dash panel, as you can see in the photo above, which is an actual photograph of the helm of the Krogen 55′ that Garmin staff have re-touched to include fully scaled images of their products.  Seeing a proposal illustrated in this fashion is a major help to the buyer.  Also visible in the Garmin illustration is the smaller 5208 8-inch MFD installed on the left, angled panel of the helm station.  This unit serves as a fully independent backup navigation unit, with its own dedicated GPS antenna.  It will also display anything on either of the two networks — the Garmin Ethernet and the NMEA 2000.  It also has its own dedicated radar antenna.  Most ocean-going yachts these days will not leave port without two functional radar systems, although one is typically larger and more powerful and serves as the primary unit.

In this case, Garmin is proposing its top-of-the-line GMR 406 Open Array/Pedestal radar for the primary system.  It isn’t as big as some of the larger units available from other manufacturers but includes several features that make it an attractive alternative.  It uses a 1.1 degree horizontal beam width, significantly narrower than most units of its size and even some larger antennas.  Narrow beam width translates into higher definition views, since the radar beam is narrow enough to distinguish between small, relatively closely spaced objects.  At 4 kW of radiated power, it’s not the strongest signal out there, but frankly, unless you are a sport fisherman looking to spot flocks of birds at the horizon, it’s absolutely sufficient and will handle collision-avoidance requirements in rain and other, less-than optimal conditions.  It also comes with full MARPA (auto target tracking), as well as some interesting features, such as selectable “look-ahead” and non-transmit zones and alarm zones.  These last features are extremely handy when using the radar in crowded locations or while anchored.

The secondary radar is the GMR 24HD, a closed array radar that also has 4kW of power.  It has similar processing capabilities and MARPA and looks like the perfect backup solution.  It’s also less than half the price of the primary system, so you get a lot for your money.

You can also see on the left-hand panel of the mocked-up display in the photo that Garmin is proposing the use of three additional, similar sized instruments.  These include, on the left,  the 4.25 square-inch color display of the GMI10 marine data instrument, which can display almost any flavor of NMEA 2000 or older NMEAA 0183 data.  Garmin suggests using one on the bridge, one in the main salon and one in the master stateroom.  Since they can display almost anything, they can be used as systems monitors anywhere they’re needed.  Next to the GMI 10 are the two displays of the redundant GHP 10 autopilots.  This is one of Garmin’s newest marine accessories and it features a patented “shadow drive” technology that lets the helmsman take control at any time by simply turning the helm manually.  Once reestablished on course, the autopilot with automatically re-engage if desired.  It has a wireless RF handheld control and is programmed with a number of unique capabilities, including the ability to follow a waypoint course without a specific limitation on the degree of turn.  Many older autopilots would disengage, or like mine, simply lose its mind when asked to turn more than a relatively limited number of degrees in order to follow a programmed course.

Garmin was the leader in getting realtime weather information displayed on chartplotters and the proposal for the Krogen 55′ includes Garmin’s GDL 30A  receiver for displaying everything from NEXRAD radar, to wave and sea states, to marine weather forecasts.  Garmin proposes enhancing this with the GWS 10 Wind Sensor, another NMEA 2000-compliant sensor that will also provide barometric pressure and air temperature — two critical measurements, in addition to the normal wind data.

As another indicator of Garmin’s continued expansion of its marine electronics lines, the company is proposing its VHF 200 radio, with the optional GHS 10 Handset microphone, which you can see hanging on the helm above, to the left of the main MFDs.  Garmin also suggests our couple install a good Single Sideband (SSB) radio for long-distance, over-the-horizon communication at sea.  In this case, Garmin recommends a unit like the Icom M-802 SSB with antenna, tuner and remote speaker.  The Garmin VHF 200 provides full class-D DSC capability via either NMEA 2000 or NMEA 0183.  Garmin doesn’t specifically note, but I’m sure would agree that there should probably be some VHF redundancy as well.  Most cruisers in this class of boat would probably have an additional fixed-mount VHF, as well as one or more handheld VHF units.  The handhelds have come a long way recently and include such features as DSC, multiple-bands and full submersible protection.  Some even float.

For depth sounding, Garmin suggests its GSD 22 2kW black box digital sounder module, coupled with a Garmin Airmar M260 1 kW in-hull transducer.  This unit can provide fish-finding and depth sounding capabilities.  Garmin recommends an additional transducer for temperature and depth sounding redundancy — an Airmar dt-800 depth and temperature, bronze NMEA 2000 thru-hull transducer, coupled to the GMI 10 Marine Instrument.

Garmin agrees that our couple should install an AIS system on the yacht.  All of the Garmin 4000 and 5000 series units allow full receive and display capability of AIS information.  Garmin says a full class A transmit and receive AIS device is “a definite must-have and safety item for any long-range and transatlantic cruising.


Garmin has grown far beyond its roots in the basic GPS market and now offers a full suite of marine electronics.  Their enthusiasm in participating in our experiment with the new Kadey-Krogen is, I think, indicative of how they are approaching the marketplace.  Their product development over the last several years has been highlighted by innovation and real value-added.  The realtime satellite weather many of us now enjoy while offshore was a Garmin innovation and the touch-screen interface is something they think has a real future, as in the 5000 series MFDs. 

I think Garmin has to be commended for its NMEA 2000 integration, as well.  All marine electronics manufacturers still use semi-proprietary Ethernet networks, but with NMEA 2000 ports right alongside, the consumer gets the best of both worlds.  If you want to know more about the details and the many trials and tribulations along the road to full implementation of the NMEA 2000 specification, check in with Ben Ellison’s PANBO blog.  Ben has more NMEA 2000 integration experience than many marine electronics technicians and he was an early, and loud advocate for a speedier implementation of this new standard.
