At last week’s Trawler Fest, our own favorite professional chef, Victoria Allman, treated a group of VIP guests of Kadey-Krogen to an evening of haute cuisine hors d’oeuvres (classy snacks).  For two evenings, Victoria gave the gorgeous galley aboard the Krogen 55′ Expedition a workout.  The Kadey-Krogen folks (author Shannon Band, actually) wrote about the show and the dining delights in their latest blog, which you can read here.  Kadey-Krogen recently upgraded the galley designs and you will now find seriously upscale features, such as Viking ranges and the like on new Kadey-Krogen yachts.

I’m planning to talk with Victoria about not only the Krogen 55′ Expedition galley, but about galley design aboard yachts in general.  As the chef aboard several megayachts for many years now, Victoria knows all about both the hardware and software (food) requirements for fine dining at sea.  If you’ve read her book, “Sea Fare, A Chef’s Journey Across the Ocean,” you know she’s a great storyteller with some delectable recipes.  In fact, Victoria just released her second book, “SEAsoned, A Chef’s Journey with Her Captain,” which complements more great recipes with the often-spicy tales of professional life aboard these megayachts.  I wonder if I’m too old to ship out?

Anyway, look for our talk with Victoria about yacht galley design here on OceanLines after we get back from the Miami International Boat Show, in two weeks.

Kadey-Krogen yesterday released more details of its newest trawler, the Krogen 52′, which we first reported on here. It’s decidedly a classic Krogen trawler, with its raised pilothouse and 3,000 nm range at about 7 knots. It shares many of the features of its bigger sister, the Krogen 58′.

The main-deck galley is “Iron Chef”-equipped (my term) with a full-size Jennair fridge and a Viking range. It also has a weather-tight Dutch door with direct access to the starboard walkway. The stairs up to the pilothouse are on the portside and feature household-standard size risers and treads. The pilothouse on the 52′ accommodates dual helm chairs.

The yacht offers either a two- or three-cabin arrangement, with the master stateroom forward or amidships. Kadey-Krogen says those opting for a two-cabin arrangement will enjoy the utility of a large, dedicated office space. Both configurations include two heads with enclosed stall shower.

The company says the boat is being offered in both single- and twin-engine configurations. The hull design will feature Kadey-Krogen’s counter-faired keel, pioneered on the Krogen 58′, which imparts a counter-rotation to water flowing into the propeller, canceling some of the propeller-induced water rotation and resulting in straighter water outflow and improved forward thrust, which implies better fuel economy than that of conventional keel designs, according to Kadey-Krogen.

In the specs table below you can see that the engine options are from John Deere, with the single 6068AFM75 offering a continuous duty (M1) rating of 231 hp.  The company said tooling will be complete by late fall this year and first delivery is planned for summer 2011. The companysays it took a “more grassroots approach and contacted current owners to see if they were interested in the project,” says Larry Polster, vice president of Kadey-Krogen Yachts. “We also took a set of plans to Trawler Fest in Fort Lauderdale and within ten days of initial exposure, the first five hulls were reserved.”

Raymarine Outfits the new Kadey-Krogen 55′ Expedition Yacht

In the third article of our series on outfitting the new Kadey-Krogen 55′ Expedition yacht with a complete marine electronics suite, we have today the recommendations from Raymarine.  Raymarine has responded to our fictional couple’s Request for Proposals with a recommended electronics suite that has at its core the cream of the Raymarine crop — the G-series High Performance Navigation System.  The Raymarine response (which you can read in full HERE) was tendered by Jim McGowan, Raymarine marketing manager.  Raymarine also provided a detailed bill of materials with suggested prices, which you can look at HERE.  McGowan notes that the Krogen 55′ Expedition

“is a true all-weather, all-water cruising boat with extended range capabilities.This boat has the capability to cruise anywhere the owner dreams to take it. Because of this, it   demands a navigation system that is technologically sophisticated, yet extremely rugged. Long ocean passages with less-than-comfortable weather conditions will be a reality for it.”

Raymarine was created in 2001 when company management bought the assets of the Raytheon Marine Division.  The technology and products from the former Raytheon division have a long a successful history in the marine field, including in the commercial arena.  The new company, Raymarine PLC, is headquartered in Portsmouth, in the United Kingdom, was listed on the London Stock Exchange (LSE: RAY) in 2004.  In the United States –Raymarine Inc., in Merrimack, New Hampshire is the principal manufacturing and management headquarters.


Raymarine believes its G-Series is the ideal electronics solution for the Krogen 55′ Expedition.  According to the company, “The modular G-Series system can be easily tailored to distribute essential navigation and monitoring information throughout the vessel.”  Since the G-Series comes with a worldwide chart database already installed, our fictional couple would have a head start on collecting the appropriate navigational materials for global cruising.

The flexibility of the G-Series is shown off in this proposal by the use of a pair of GPM400 processor modules, which will handle all the computational and information distribution duties, and drive two G190, 19-inch ultra-bright sunlight-viewable marine displays.  These processors are capable of monitoring and controlling an impressively extensive array of sensors and systems aboard the yacht.  Raymarine’s product line extends farther than many of the other companies to include products in the communications, entertainment and small-boat autopilot categories. McGowan expands on the company’s rationale for the G-Series:

On a boat of this size, the action is not always happening in the pilot house. That is why we have provided for distribution and monitoring of our navigation systems throughout the boat. Each of the GPM400 processor modules at the heart of the system features dual video outputs. One of each will go to its respective G190 monitor in the pilothouse. The secondary outputs will go to LCD or Plasma televisions mounted below in the main salon and owner’s stateroom.

Using a wireless G-Series Command Center Keyboard, we can offer the Captain and crew full control of the system from any of these locations. We will fit a wireless keyboard for the main salon area and another for the owner’s stateroom.

By simply toggling the video source on the television to the input from the bridge, we can now see and control the system. For example, one could have the radar and chartplotter visible in the main salon while they are at anchor and keep a watch on the surrounding traffic and the boat’s position in the anchorage. They could call up the video feed from any of the boat’s onboard CAM50 or CAM100 cameras to see what is happening elsewhere on board.


Getting into the guts of the Raymarine proposal, the system starts with the two GPM400 modules at the network heart.  Pre-loaded with Navionics Platinum cartography for North America and Europe, they also have Navionics Gold-level charts for the rest of the world.  The two 19-inch displays, centered on the helm, provide windows into and control of the rest of the system, using a G-Series Compact Keyboard in the pilothouse.  Raymarine proposes using two (or more) G-Series Wireless Command Center keyboards, which will work anywhere onboard.  Interestingly, the company offers a wireless upgrade kit that can add that capability to any G-Series Command Center keyboard, communicating with the G-Series system through a wireless SeaTalk base station.  SeaTalk is Raymarine’s proprietary networking protocol.  Proprietary protocols used to be a significant impediment to integrating outside products into the networks of the big marine electronics manufacturers.  But with the advent, and increasing adoption, of the NMEA 2000 networking protocol, adding devices of multiple manufacturers to one network is almost seamless.  The G-Series SeaTalkhs protocol interfaces with NMEA 2000 data so information from other companies’ sensors, including engine data, is simple.

Instrumentation and Data Monitoring

Raymarine suggests taking advantage of the overhead flats above the helm in the Krogen 55′ Expedition for installation of a second tier of full-color instrumentation from the new ST70+ line.  In fact, the instruments are so new they’re not on the company’s website yet, but you can read a little more about them on Panbo.  They are controlled by a small, flush-mounted keypad on the console, “so there is no need to reach or stretch to make adjustments,” according to Raymarine.  They are high-resolution, 6.5-inch displays, fully sunlight viewable and also switchable to nigh-time viewing mode.  They can display water depth, wind speed and direction, engine data, navigation status and some other information.  Raymarine suggests supplementing them with some ST70+ analog repeaters for wind speed and direction as well as rudder angle; the traditional analog needle display perfect for at-a-glance viewing.

Raymarine suggests the Krogen 55′ Expedition be fitted with a primary RA3072HD Super High Definition open-array scanner.  According to the proposal,

“This unit has a 72” open-array scanner with an ultra-narrow 1.1° horizontal beam width, 12 kW of power and a 72 nautical mile range. That, combined with Raymarine’s Super HD Digital Processing combines to present a super-detailed radar presentation with lifelike clarity.

The secondary radar will be Raymarine’s new RD424D Digital Radome scanner. With 4kW of transmit power and a 48 nautical mile range this radome is built to perform and is great solution for both close-in and long range monitoring.

The G-Series system includes a 25 target MARPA collision avoidance system standard.”


The Raymarine recommendation is for its DSM300 HD Digital Sounder unit and a B260 thru-hull transducer.  The company says this will give the best possible underwater and bottom imagery at all times without the need for any manual tuning or tweaking.  The DSM300 has 1000 watts of Transmitter power and uses both 50 and 200 kHz frequencies.


Like the other electronics manufacturers in our series, Raymarine believes strongly that AIS should be installed on our couple’s Krogen 55′ Expedition.  Raymarine recommends its AIS500 Class B AIS transponder.  The target data can be overlaid on both the radar and chartplotter displays.  Raymarine’s unit also has a feature called “Buddy Tracking,” in which the MMSI numbers of familiar vessels are programmed into the G-Series system.  When any of these vessels appear on AIS, they are called out on the chart and radar displays with a name that can be specified and with a unique AIS “buddy” symbol.  Raymarine says this makes it easy to identify friends’ boats or even keep track of a flotilla when traveling in a group.

Raymarine also suggests our couple install an AIS500 transponder on the Krogen 55’s tender, along with a Raymarine A70D compact chartplotter/fishfinder unit and Ray 49 Class D VHF radio.  While these represent additional expenses, the security enhancement and peace of mind from being able to know where your tender is at all times when cruising in remote destinations is decidedly worth it.  It would probably be overkill for a local-only cruiser, but most Krogen 55′ Expedition owners will head to more remote waters with their new global-capable vessel.

Weather and Environmental Data

The proposal suggests our couple outfit the boat with an array of sensors, including an ST70 wind pod and masthead transducer for wind speed and direction, which will be repeated across the entire network.  An ST70 speed and temperature pod, along with a bronze thru-hull transducer will also be fitted, enabling the G-Series system to compute such things as real-time set and drift, true wind speed and direction and velocity made good.

Raymarine says the G-Series plotters can display all these vectors so the captain “can see at-a-glance how wind and currents are impacting the motion of the vessel.”  Raymarine also outfits the boat with their SR100 Sirius Marine Weather Receiver, which will stream live data to the G-Series system.  The Sirius system is GPS-aware, meaning it uses shipboard GPS location information to customize the weather information for your location.  It also enables alerts for breaking weather developments and storm warnings.

Safety and Surveillance

A unique element of Raymarine’s proposal for our Krogen 55′ Expedition is the recommendation for Raymarine’s LifeTag Wireless Man Overboard system.  Here’s how they describe it:

Using Zigbee secure wireless communications, each crewmember can be issued a small LifeTag pendant which is easily worn on the wrist or arm, clipped to their belt, or attached to a life vest or foul-weather garment. Up to 16 pendants can be monitored by the LifeTag base station at a time. If a user goes overboard, the base station will alert the Captain and crew to the emergency by sounding the included man-overboard alarm. Furthermore, LifeTag is integrated into the navigation network and will automatically trigger the man-overboard response mode on the G-Series Navigation System. This includes automated actions like marking the GPS position of the alarm, automatic reporting of bearing and range to the alarm position, calculation of elapsed time in the water, and other actions.

For monitoring interior and exterior spaces, Raymarine proposes installing a series of CAM100 and CAM50 marine cameras, connected to up to two GVM400 Video Modules for distribution of the video streams.  The CAM100 is a heavy-duty, waterproof camera designed for outdoor installations and equipped with a zero-light capability using its own infrared illuminators for a total darkness range of up to 30 feet.  The CAM50 devices can monitor interior spaces.

Engine Data Monitoring

Raymarine says its G-Series and ST70+ systems can both monitor the data from NMEA 2000-compatible engines and generators.  Up to three main engines and four auxiliary generators can be monitored simultaneously.  The ST70+ instruments can also monitor fuel, fresh-, gray- and black-water tank levels.


In the pilothouse, Raymarine would install a Ray218 VHF radiotelephone.  This is a full Class D DSC radio that also features an external loudhailer and automatic fog signal generator.  The Ray218 can also be remote-controlled using a RayMic second station microphone.  Raymarine suggests mounting a RayMic down below in one of the common areas for convenient access when at anchor or in-port, or on one of the bridge wing-control stations.  The company says that a backup VHF is both a convenience and a necessity on a boat of the size of the Krogen 55′ Expedition.  “Near the chart table, we will install a Ray55 DSC VHF radio.  This radio offers nearly all of the same features as the Ray218, minus the loudhailer and foghorn.”  Raymarine suggests that a remote RayMic for this unit could be in a locker on the aft deck or in the owner’s stateroom or opposite wing-control station on the bridge.

Entertainment Options

Unlike the other companies, Raymarine also has its own satellite TV antenna, in this case the Raymarine 60STV-HD Satellite Television Antenna System.  Here’s how they describe this system in their proposal:

With multi-satellite support for DirecTV, Dish Network and Express Vu, the 60STV offers superior coverage anywhere in North America. Raymarine’s exclusive Wide Range Search algorithms and Dynamic Beam Tilting (DVB) technologies make satellite acquisition and tracking fast, steady and reliable in even the most extreme weather conditions.

Fully stabilized to counter the motion of the boat while underway, 60STV also features conical scanning for maintaining the strongest possible signal, and a unique rotating sub-reflector minimizes the need for constant dish movement resulting in much quieter operation than competitive units.

60STV’s standard dual LNBs offer support for multiple receivers (think TV in multiple staterooms) while its simplified cabling makes installation easy.


For our couple’s Krogen 55′, Raymarine recommends installing the new SmartPilot X-30 hydraulic system, with a combination of fixed and wireless controllers.  The core pack for this system includes an integrated rate-gyro sensor which enables the autopilot to detect the most subtle yawing motions of the vessel, enabling it to make smarter decisions about how to best hold the boat on course.  This means being able to minimize large-scale movements, which saves fuel.  The X-30 is naturally integrated with the rest of the navigation system and can take navigation guidance from the G-Series plotters.  And if our couple notices some tuna schools under the boat with the DSM Sounder, they can use one of the X-30’s pre-programmed fishing patterns to lure the pelagics to the dinner table.


Raymarine has proposed an extremely comprehensive electronics suite for the Kadey-Krogen 55′ Expedition.  It utilizes Raymarine’s top-end G-Series processors and displays and takes advantage of both the company’s high-speed SeaTalk network and NMEA 2000 protocols to deliver almost unlimited systems and information monitoring and control capabilities.  With major installations in the U.S., Europe and Asia, our couple won’t have any trouble getting support or replacement parts if trouble should arise while cruising.

If you would like to talk to Raymarine about their proposal for the Krogen 55′ Expedition or any of their other marine products, you can visit them at the Miami International Boat Show and Strictly Sail, at booths A95 and A100 at the Miami Beach Convention Center site.  If you’re going to the show, stop by and see the actual Kadey-Krogen 55′ Expedition at the Sea Isle Marina in  Miami at dock 808, slips a, b and c.

Furuno Outfits the New Kadey-Krogen 55′ Expedition

For more than sixty years, since the commercialization of the first electric fish-finder, Furuno has been a pioneer in the development of marine electronics.  OceanLines asked Furuno USA to participate in our hypothetical outfitting of the new Kadey-Krogen 55′ Expedition trawler.  The company responded with a proposal from Matt Wood, Sales Manager for Furuno USA.  Furuno’s proposal represents a state-of-the-art suite of multifunction units, sensors and networking technology, focused around the company’s NavNet 3D product line.

Wood 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 Furuno package — the Response to the RFP, as well as a spreadsheet file that includes an extremely detailed list of the proposed basic and high-end electronics suite.  Here’s an overview.


Wood notes in his letter to our fictional boat-buying couple that Furuno has a long history of equipment installation on Kadey-Krogen yachts all over the world and is familiar with the requirements of cruisers in this segment.  The Furuno proposal offers a basic package, which our couple asked for, as well as a top-of-the-line outfitting package that adds capabilities, as well as redundancies.  The proposal also highlights the seamless connectivity not only of the Furuno-branded NavNet products, but, using the NMEA 2000 networking protocol, the many other systems and sensors available in the marketplace.

Furuno Recommended Equipment and Pricelist for Krogen 55' Expedition

Furuno Recommended Equipment and Pricelist for Krogen 55' Expedition

The Furuno proposal notes that its equipment was the exclusive choice for the lead vessel in the PAE/Nordhavn North Atlantic Rally in 2004, when several trawlers made a group crossing from Florida to Gibraltar.



In his letter, Wood notes that 

“Since the plotter and radar functions are so seamlessly connected in the current era, Furuno will propose the integrated NavNet3D system.  For the basic layout this will include two NavNet 3D MFD12, 12-inch LCD multifunction displays.  According to Furuno, “These full-function plotters include both raster and vector chart databases for the entire US coastline and offer true three-dimensional navigation.  The NavNet 3D (or “NN3D”) MFD series offers complete chart plotter, radar and sounder integration.  Additionally, the MFD12 and other displays offer radar ARPA, AIS, Sirius weather, weatherfax and other interfaces such as display of camera information and NMEA2000 instrumentation.

Two MFD12 units side-by-side in the main panel of your Kadey’s dash will provide one screen for plotter navigation with or without radar overlay, and an additional/redundant screen for alternate chart views, route planning, instrumentation, cameras – the options are virtually limitless.

The basic installation includes a DRS4D, 24-inch 4KW 36-mile radar antenna.  This compact and lightweight radome antenna will be perfectly adequate for the coastal navigation you propose from Alaska to Florida and beyond.  The DRS antenna series uses Ultra High-Definition signal processing to give a remarkably clear radar picture.  In fact, it’s like having two radars in one – the Navnet 3D MFD series offer true, dual-range radar capability.  One range can look far for weather and coastline, while one range can be set close in for collision avoidance.  In a fishing application, one range can be set to look for birds diving on bait, while one can be set close in for safe navigation.

All NN3D units include a built-in 30-target ARPA – Automatic Radar Plotter Aid – so it’s not a mere MARPA, or mini-ARPA.  The ARPA will use the data from radar, GPS and the autopilot’s heading sensor to generate rock-solid target lock on up to 30 targets, either manually or in auto-acquire mode.
The MFD12 unit offer both video input for external video sources (such as a camera) as well as video output.  The video output from either or both MFD12 would be used in the stateroom and salon monitors.  In this configuration, that video presentation would be “static” – or not controlled in the stateroom or salon – unless and additional MFD unit was installed in either location.  See notes on the FMD8 second-station below.”

Furuno says that in the higher-end package, they would recommend replacing the two MFD12s with a single NN3D MFDBB — “Black Box” — plotter processor.  In this option, the display chores would be handled by two 17-inch MU170C color, sunlight-bright LCD units.  Furuno refers to these as “glass bridge” monitors.  They have multiple video inputs and so can display data from several different sources, including in Picture-in-Picture (PIP) format.  Furuno says the black box processor is unique in the industry in that it can operate in an “Extended Display” mode, which uses the single processor to drive two separate displays.  While the NavNet 3D MFDs can also display video inputs, the plethora of video input operations on the black-box-driven LCDs will accommodate more separate sources.


For radar, Furuno suggests a 6kW open-array radar, using a 6-foot antenna.  “While many vessels have crossed oceans with less radar or with none, we recommend the 6kW or even 12kW radar sets for long-range cruising.  The increased power and longer antenna array give increased range and better ARPA performance — both desirable when out on the Big Blue.”

The company suggest for both installation options the use of a smaller, 8.4-inch MFD8 display for use at a remote station.  “Given the layout of the [Krogen 55′} we propose that the MFD8 be centrally located on the back deck for use at a remote steering station.  Visual access from the back deck will come in handy when fishing as well, as the MFD8 can be used as a network sounder display for reeling in the big one!”


Furuno proposes a suite of network sensors, operating across the integrated NavNet 3D and NMEA 2000 network.  For example, they propose to fit both a GP330B NMEA 2000 network GPS sensor as well as a GP32 stand-alone GPS/WAAS navigator.  “Both position fixes can be input to the NN3D system and the NMEA 2000 network will automatically switch GPS sources if position fix should be lost…”

 Furuno says that one of the advantages of  its DRS (digital radar) antenna units is that “multiple Furuno sensors can be installed on a MNEA 200 backbone “stub,” which then connects directly to the DRS antenna.  The DRS converts the data for use in the NN3D display — so only one cable needs to be run down the mastfor the NN3D sensor suite.”  Furuno claims rightly that the simplified installation will save significantly on labor costs for running the cable as well as the wiring and data integration.

Known for many years in the commercial fishing industry for its fishfinders, Furunoproposes to install a digital, black-box sounder module — the DFF1  — to provide depth and bottom information to the NN3D suite.  Furuno would pair the sounder module with a 1kW thru-hull transducer to ensure deep-water performance.

For realtime weather, Furuno proposes the BBWX1 satellite receiver, which provides subscription-based Sirius weather info for use in the network as well as any shipboard PC systems.  As with all marine realtime weather products, various subscription packages are available from the weather service provider, now Sirius/XM after the corporate merger.  To enhance the overall weather awareness, Furuno would also install its FAX30 dual-duty black-box unit for providing weather fax reception and storage as well as NAVTEX safety messages.


Furuno believes some form of AIS is essential for our hypothetical cruisers.  In a basic package, Furunocould provide its FA30 receive-only AIS unit.  But the company believes strongly that for both the basic and high-end installations that a true AIS transponder system be utilized.  Furuno proposes its FA50 Class B AIS, which will both transmit your own vessel information to others as well as show you the information of other AIS-equipped vessels.  Wood puts it convincingly in the proposal:  “While a receive-only AIS unit enables YOU to see THEM, in the cse of a tanker in the fog in the Straits of Juan de Fuca, don’t you want to be sure that THEY see YOU?”  Given that the price differential between simple receive-only Class A units and full duplex Class B transponders is likely to continue to diminish, it seems prudent to outfit our cruisers with the full capability.

Interestingly, and logically, Furuno proposes that our couple equip their tender with an FA50 AIS as well.  A watch stander can keep track of the tender’s whereabouts even on the vessel’s chartplotter displays.  Might not be a bad idea if the tender wanders around too many headlands.  As long as it’s still wtihin clear VHF range, the folks aboard their Krogen55′ will still see it and can guide it home.

As befits its status as one of the oldest marine electronics companies still in the marketplace, Furuno has fulll proposals for communications, autopilot and additional instrument capabilities.  Furuno’s proposal suggests two of its FM3000 Class D VHF radios, each fitted with a remote mike/speaker for use in other areas of the boat.  Furuno also has an SSB radio for long-distance communications; the FS1503EM has a modification for direct connection of a modem for e-mail.  Furuno would also install its LH3000 loudhailer for those times when a loud voice, or foghorn just has to be used.

Furuno also gets into the use of a PC aboard ship, noting that most long-distance cruisers nowadays, and not infrequently for navigation as well as the more traditional PC duties such as e-mail and home office activities.  Furuno says its MaxSea Time Zero Explorer program can be employed on a shipboard PC, and has the advantage of using the same charts as the NN3D system.  A tender-tracking module can be included in the MaxSea TZ installation.


Autopilot duties will be handled by the NavPilot 500, complemented by some state-of-the-art heading sensor technology.  The company’s new SC30 Satellite Compass is a dual-antenna GPS compass that offers “gyrocompass-equivalent heading information,” according to Furuno.  The upgraded SC50 unit offers even more precise steering information.  The satellite compasses offer pitch and roll correction, which can be used by keel stabilizers.  Heave compensation can be used to stabilize the echosounder presentation, as well.

As with most of the other equipment categories, Furuno has a plethora of additional instruments to choose from.  In particular, the company suggests at least an RD30 unit for use as a navigation information repeater, and redundant depth indicator.  The PB150 ultrasonic wind and weather sensor can connect to the RD30 and a PC.  One interesting note is that the NN3D network can easily display digital engine information, which is likely to come from newer engines over a J1939 buss.  Converters to translate that information to NMEA 2000 format are available from many suppliers.

For cruisers who want to fish seriously, or perhaps navigate tricky channels or perhaps, iceberg-studded waters, Furuno can even supply its CH250 or CH300 series searchlight sonar.


The truth is, Furuno has such an extensive line of recreational and commercial grade marine electronics, that the sky is the limit when outfitting a boat with the company’s products.  The company’s long history and reputation for reliability in the commercial segment gives it a big leg up in the recreational market.  That is not to say the recreational products are somehow inferior to the commercial units.  In fact, the NavNetvx2 series is the standard U.S. Coast Guard navigation product for all vessels under 85 feet.  Matt Wood notes in his letter to our buyers that it is even possible to integrate much more powerful radar units, such as some of the commercial grade (which usually means certified for oceangoing use) FAR radar series.

As with most of the other electronics companies, Furuno does not offer entertainment systems or satellite TV units as part of its product mix, but these are widely available and relatively easy to integrate to the extent that is necessary.

Check out the links above in the story to see the full proposal from Furuno as well as its bill of materials and price estimates.  Here at OceanLines, we would like to thank Matt Wood, Jeff Kauzlaric and all the systems specialists at Furuno USA for participating in this project. 

If you would like to talk to Furuno about their proposal for the Krogen 55′ Expedition or any of their other marine products, you can visit them at the Miami International Boat Show and Strictly Sail, at booth # 1617 at the Miami Beach Convention Center site.  If you’re going to the show, stop by and see the actual Kadey-Krogen 55′ Expedition at the Sea Isle Marina in  Miami at dock 808, slips a, b and c.

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.

Check out the full text of Garmin’s proposal and its proposed, general network schematic in the links above.  Here at OceanLines, we extend our thanks to Garmin, and in particular to Carly Baltes, Greg DeVries, and the talented systems specialists and artists who contributed to the project.

First Kadey-Krogen 55′ Expedition Arrives in U.S.

Kadey-Krogen 55' Expedition Hull 1 Invictus Upon Arrival in U.S.

Kadey-Krogen 55' Expedition Hull 1 Invictus Upon Arrival in U.S.

Hull # 1 of the new Kadey-Krogen 55′ Expedition line has arrived at the company’s Ft. Pierce, Florida headquarters and is now being commissioned and prepped for her debut at the Stuart, Florida Trawlerfest later this month.  KKY Vice President Larry Polster said in a posting on the company’s website that the delivery by freighter to Savannah, Georgia and subsequent offloading and transit to Ft. Pierce, was uneventful — which is generally a good thing for a new boat.

The first boat is named Invictus and will belong to Bill and Lisa Roberts.  Bill’s grandfather had sailed around the world in a sailboat of the same name, which is derived from the poem of the same name by William Ernest Henley.

Have a gander at the Kadey-Krogen photos of the arrival and unloading of Invictus in Savannah here,

. . .then stop by the KKY website and read Larry Polster’s account of the arrival and first trip to sea for the 55′ Expedition here.

And just because sailors and seamen of all kinds will find resonance with its spirit, herewith the full text of Henley’s poem:


Out of the night that covers me,
Black as the Pit from pole to pole,
I thank whatever gods may be
For my unconquerable soul.

In the fell clutch of circumstance
I have not winced nor cried aloud.
Under the bludgeonings of chance
My head is bloody, but unbowed.

Beyond this place of wrath and tears
Looms but the Horror of the shade,
And yet the menace of the years
Finds, and shall find, me unafraid.

It matters not how strait the gate,
How charged with punishments the scroll.
I am the master of my fate:
I am the captain of my soul.

William Ernest Henley, 1849-1902
