A Closer Look at the New Krogen 52′

Kadey-Krogen’s recently announced 52′ is a classic example of a builder filling out a product line in specific response to customer demand. In this case, the company already had on offer its well-established 48′ and the new 55′ Expedition. The 55′ Expedition, however, is not really the “other” boat in this comparison — it’s the Krogen 58′ which was more of a model for the new 52′. In a recent interview, Kadey-Krogen Vice President Larry Polster talked about the boat itself and what kind of customer is the target for the new 52′.

With the first signs of the economic recovery beginning to emerge in the recreational boating industry, Kadey-Krogen is optimistic about the market for the new boat. “There’s clearly a market for bigger boats — upper 40s to mid-50s,” says Polster. He says the company originally had a hole in its lineup that stretched from the 48′ to the 58′ and originally started out designing a 53′. But input from the early customers on that design turned it into the 55′ Expedition, a significantly different design that the traditional Krogen. And the price wasn’t between the two original yachts, either.

Polster says the 52′ is better understood as a smaller 58′, rather than a larger 48′. And of course, he emphasizes, the new boat is designed fresh from the keel up. “It’s a purpose-built boat; not a stretched hull,” says Polster. The familial resemblance to the 58′ can be seen in details such as the Portuguese bridge, the Dutch door in the starboard-side galley, and the open office space below. So, the 52′ will appeal to those who like the design of the 58′ but might be intimidated either by the size or the price. And yet, it is substantially roomier than the 48′, not least because of the extra foot of beam (17′-9″).

Interestingly, all of the launch customers have chosen the same layout — master stateroom forward, twins to starboard, and a convertible open office to port. Kadey-Krogen has converted several of the initial letters of intent to firm contracts and construction is on schedule.

As a clean-sheet-of-paper design, the new 52′ is one of the few boats of her size that was designed from the outset for the baby boomers who started retiring last year. Manufacturers today — from the boat builders themselves to systems providers like KVH — understand that liveability aboard is key to success with the boomers. That liveability issue is directly related to keeping household standards. Not only do you see household-standard appliances and near-shore size beds and head fixtures, but even minor details like stair steps. “We’ve taken great pains to make all risers and treads house-standard,” says Polster. “The magic ratio is about 17 — rise plus run — but a tread of only 7″ is hard to stand on.”

Kadey-Krogen expects high efficiency from the 52’s hull. Predicted performance at a speed/length (s/l) ratio of 1.1 shows the requirement for 70 hp, moving the boat at 7.6 knots. The boat will displace 70,000 lbs at half-load. Standard engine is a 231 hp John Deere (all Krogens have JD power), and the genny will be a 12kW Northern Lights set.

The new 52′ has a competitive base price right now of $1.295 million. That compares to a base of $949K for the 48′ and $1.595 million for the 55′ Expedition.

One interesting side note: the question often arises — how big a boat do I need to live aboard? Obviously, there can’t be only one answer to that question, but in Kadey-Krogen’s experience, the answer is — “somewhere in the 40’s.” “We built 50 of the 39’s and as far as I know, only one couple lived aboard full-time,” says Polster. One size up, however, and it’s a different story. “The 42′ is a little bit longer, but a full 18″ wider in beam and tons of owners are full-time liveaboards.”

PAE Launches the Nordhavn 63

Pacific Asian Enterprises has announced the latest of the 4th generation Nordhavns, the Nordhavn 63.  This new model builds on the successful 55 hull but uses new deck and engine room molds for a roomier, more efficient layout.  The 63 has a narrower hull than the famous Nordhavn 62, which together with the 46 represents the first generation of Nordhavns.  The new 63 will appeal to people who want the roominess and overall size of the 62 but can’t find a slip for the 20 foot 4-inch beam of the earlier model.  The beam on the 63 is 18 feet yet the engine room and some interior spaces will feel much roomier than on the 62.

If you take a look at the Nordhavn line, there is a very interesting crossover point, a couple of them actually, in the mid-size models.  We’ve put some of the key measurements in the table below.  The 55 is the starting point, as it’s the hull for both the 60 and 63.  The 55 has a forward (mid) pilothouse; the 60 keeps the same deckhouse but adds five feet in the aft cockpit, and finally the 63 moves the pilothouse aft and has the same measurements as the 60, except that it draws more water.  In the midst of all these new, fourth-generation models, is the staunch veteran of the fleet — the 62; a first-generation Nordhavn that the company just can’t seem to kill.  People still want to buy it because of its unequaled reputation as a tough, tried-and-true bluewater boat.  The 62 is almost a foot-and-a-half wider than the newer 50/60/63 models and displaces almost 50 percent more.  Only when you move up to the 64 and 68 do you get back into that weight class.

Comparative Specifications for Norhavn Mid-Size Yachts

One of the driving forces for the 63 was customer demand for an aft-pilothouse boat like the 62, but with more room and less beam.  Sounds like a tough design challenge; except that Nordhavn had the 55 hull to work with.  In fact the launch customer for the 63, a couple from the mid-west, couldn’t find a 20-foot slip in their desired homeport, which forced the narrower beam requirement.  It won’t be much of a compromise, however.  The 63 has nearly two more feet of length at the waterline than the 62 and nearly three feet more length overall.  Combine those with the new interior molds, enabling the larger engine room and better layout, and you have the reason Nordhavn agreed to do the boat.

Among the new features enabled by the interior mold changes are the crew quarters just forward of the engine room, with both a fixed and pipe berth.  There is also a standard centerline guest stateroom and four large, opening port lights.  The 63 will also feature a standard raised-panel cherry, first seen on hull #1 of the 75 Expedition Yachtfisher.  The galley will have two V700 series Subzero refrigerators and one freezer.  The main salon on the 63 is larger than that on both the 55 and 60 and offers two wrapping settees for entertaining, with the galley on the same level.

The 63 will be powered by the John Deere 6081AFM w/M3 rating of 330 HP @ 2,300 rpm, which is keel cooled to enable a dry stack exhaust. The transmission is an equally bullet proof ZF ZFW320 with a 4 to1 reduction gear. The Nordhavn 63 has a projected fuel capacity of 2,250 gallons contained in four main tanks and one aluminum “day tank” holding 31 gallons which will gravity feed from main wing tanks and center tank.  As with all Nordhavns a range of at least 3,000 nm is projected.

The large open foredeck can support a tender as large as 17 feet and it comes standard with a Steelhead ES 1500 telescoping yacht crane with a 1500-lb. safe working load.  Another design cue taken from the N75 EYF is the updated dry stack which trails aft of the radar platform and forms the support for the dual tracking domes atop the pilot house.

Delivery of hull #1 is expected in late 2010.

Kadey-Krogen Confirms Launch of 64′ Expedition Program

Artist Rendering of New Kadey-Krogen 64' Expedition Yacht

Kadey-Krogen yesterday confirmed that it is proceeding with a program to build a new flagship for the company’s model lineup; the 64′ Expedition.  As first reported here in Oceanlines last November, the new boat is designed to combine the seaworthiness and classic lines of the Expedition series with maximum interior spaces.  We’ve included the latest illustrations of the design from Kadey-Krogen. They haven’t changed too much since the original back in November. The company has settled on a continuous-duty rated engine from John Deere. The following description is from the Kadey-Krogen press release:

“Until now, the largest model offered by Kadey-Krogen has been their 58’ but the company believes there is room and interest in their buying audience for a bigger model so long as it can still be handled by a couple. The 64’ Expedition is designed to be handled comfortably by two people, yet guests and/or crew can be accommodated with privacy for all as the 64′ is available with multiple cabin and head layout options.

The saloon of the 64′ Expedition is located where every Kadey-Krogen saloon can be found: forward through the welded aluminum weather-tight doors off the fully covered aft deck. The portside galley remains amidships, directly adjacent to the saloon, so those who are prepping and cooking are still a part of the conversation. The galley is well appointed with top-of-the-line stainless appliances including a four-burner Viking range, full-size Jenn-Air refrigerator, a super-quiet Miele dishwasher, a microwave/convection oven, and trash compactor. As a first for Kadey-Krogen, there is a separate dining room to starboard, opposite the galley. The design crew at Kadey-Krogen can also accommodate the “must-haves” of an owner and will ensure the 64’ Expedition meets the needs and expectations of its owners.

A wide walkway along the starboard side provides exterior access from the aft deck to the massive foredeck that is capable of handling a 17-foot tender and related equipment. For those that favor the looks of an expedition yacht but prefer to operate a vessel outside the pilothouse in fair weather, the 64’ Expedition is available with a flybridge. Kadey-Krogen vice president, Larry Polster, believes this new boat gives the company an opportunity to showcase how it can cater to cruisers who favor designs with maximum interior space without compromising handling, safety, or range. He also points out the architectural integrity of the design and says, “We don’t stretch boats. The 64’ is built using a dedicated mold and like the 55’ it incorporates three keels. Engineering aboard the 55’ was so well received that it was natural for Kadey-Krogen to extend those features and functions to the 64’.” Both Expedition models offer complete access to all machinery spaces from a single point of entry. Owners can move from the rudder post to the bow thruster through watertight doors in a machinery space boasting 6’6” of headroom. This feature makes the 64’ unique in class and size, setting the 64’ apart from its competitors.

The innovative three-keel design by Kadey-Krogen allows the Expedition model to have greater fuel efficiency than other keel forms. Each of the skegs to port and starboard is counter-faired, with the trailing end specially shaped to rotate water flowing into the propeller in the opposite direction of the propeller rotation resulting in greater operating efficiency.

The balanced, easy to propel hull form combined with continuous duty 231hp John Deere engines gives the 64’ a range of 3,000nm at 9 knots. Supporting equipment in the engine room includes fuel polishing, oil exchange, and fire suppression systems; hydraulic stabilizers as well as bow and stern thrusters; chilled-water air conditioning; and a universal power converter—all are standard.

Like all Kadey-Krogens, the hull is built using vinylester and isophthalic resins, knytex mats, and US-made Cook® UV-protected gel coat to protect the vessel’s gel coat. Critical areas of the hull will be reinforced with a special impact-resistant fiberglass mat containing Twaron, the same fiber used to give body armor its “bullet-proof” capability. Twaron is an aramid fiber that is five times stronger than steel and up to 60% lighter than ballistic steel. This strong yet light fiber helps maintain a moderate displacement-to-length ratio that is a signature of Kadey-Krogen engineering and again results in better fuel economy.”

Some more of the latest renderings, including an alternate white hull.

Northwest Trawlers Launches First 50′ Passagemaker

Northwest 50' at dock

Peter Whiting, co-founder of the Northwest Trawlers line reports that the Anacortes, Washington-based company has launched hull #1 of the NW50 series, a big sister to the original NW45.  NW 5001 was launched in La Conner, Washington, and is now undergoing final commissioning work.  As of this writing, the boat should be heading out for first sea trials.  The boat’s hull was designed to accommodate both hull-speed cruising up to the mid-teens.  We’l try to catch up with Peter in the next few days to get a report on the sea trials.

The NW50 is a big, strong boat with Kevlar in the forward hull sections and a tall, seaworthy bow with a Portuguese bridge to further protect the pilothouse.  An articulated rudder and standard bow thruster make the NW50 more maneuverable in tight situations.  The company says its designs are all about accommodating customers’ wishes in decor and outfitting.  An example is the extra pilothouse port light just aft of the main pilothouse windows.  The launch customer wanted the additional light and ventilation possibilities from this opening port light.  By the way, Peter says the owners are still looking for a good name for the boat, so if you have any suggestions, forward them to Peter at NWTrawlers

Here’s a link to the spec sheet for the NW 50 (Spec Sheet).

And here’s a photo gallery of the launch evolution and the boat sitting nicely on her lines at the dock.

Northwest Trawlers Adds 55 to Model Lineup

Northwest Trawlers Founder Peter Whiting has announced that his company is adding a new flagship to the company’s fleet — the NW 55. Designed by Steve Seaton, the NW 55 keeps the look of the Northwest 45 and 50, but adds a newer, more streamlined flybridge that will eventually make its way to the 45 and 50 as well.

Northwest says the 55 will come standard with a John Deere 6125, with 610 HP. A preliminary fuel load of 1,400 gallons should give the yacht a range of approximately 2,800 NM at 8 knots. The boat will hold 400 gallons of water and Whiting says preliminary specifications call for black and gray water tankage of about 200 gallons.

Krogen 55 Expedition to Debut at Miami

Kadey-Krogen’s new Krogen 55 Expedition will make its public debut at the Miami International Boat Show in February 2009, just six months from now.  The company said construction of hull number one is continuing apace at the company’s construction partner shipyard, Asia Harbor Yacht Builders, in Kaohsiung, Taiwan.

While obviously intended to fit the gap in the product line between the Krogen 48 North Sea and the biggest model, the Krogen 58, the new 55 Expedition combines significant design elements from either end of the spectrum.  She incorporates the 360-degrees of visibility from the pilothouse, a hallmark of the discontinued Whaleback 48, as well as the three keels in her hull, taken from the 58.  Each of the skegs, to poort and starboard, is counter-fairs such that the trailing end is shaped to import a rotation to the water flowing into the propeller that is contrary to the propeller rotation, says Kadey-Krogen.  The company says this count-rotation cancels the prop-induced flow rotation, thereby improving forward thrust.

Krogen 55 Main Deck Plan

The 55 Expedition is a classice Kadey-Krogen full-displacement yacht, intended to cover long distances in luxurious comfort.  She’s not the heaviest of her class, but with approximately 6,900 pounds of ballast, she displaces about 88,000 pounds at half load.  Her 1,880 gallons of diesel will take her 3,000 miles at 8 knots, or, as the company says, from Annapolis to Antigua nonstop at 9 knots.  The 55 is powered by twin John Deere 6068TFM M1, Tier 2 diesels, rated at 158 BHP at 2,400 RPM.

Pilothouse Layout of the Krogen 55 Expedition

The boat draws 4′-10″ at half load and was designed with an air draft that will allow reaching the Great Lakes via the Hudson River and Erie Canal system.  Height above DWL, not including the mast, is 17′-7″.  While cruising those canals, the boat can hold 140 gallons of black water and 140 gallons of gray water.

The Krogen 55 Expedition is built to handle serious ocean water.  Her hull is reinforced at the stem and stern bottom with an aramid fiber similar to Kevlar ™.  Watertight crash bulkheads are also incorporated to increase safety at sea.  The list of standard equipment on the 55 is extensive, and includes stainless steel applicances by Jen-Air, Miele, Viking and GE.  A Northern Lights 16kW generator is included as is a bow thruster and stabilizers from ABT.

Extra nice touches included in the $1.895 million base price, are a standard fuel polishing system, Nautical Structures Euro 1,200 lb. lift capacity davit, with auto rotation, and two wing control stations.
