We’ve got a great collection of photos of the very first Nordhavn 63, Silver Spray, taken by Billy Black in Stuart, Florida, for P.A.E. last month just before delivery.  There is quite a bit of detail to absorb and the photos leave you with the overwhelming impression of a luxurious, capable bluewater yacht.  I happen to think this might be the perfect size for a couple to handle without crew, although Ken and Roberta Williams demonstrate that the N68 is manageable for a couple, too.  If you haven’t seen the initial performance data, you can view it here.

We’d love to hear your thoughts and comments on the yacht’s features and decor.  Let us know in the comments.

First Nordhavn 63 Performance Data

Pacific Asian Enterprises, Inc., yesterday released the first published performance data for the new Nordhavn 63.  The data are from the first hull, Silver Spray, which was just delivered to its owner at PAE’s Stuart, Florida commissioning facility.  As you can see in the accompanying photo above, taken by the yacht’s owner, the N63 truly looks like the “next-generation” N62, the aft-pilothouse trawler that was a customer and fan favorite all through its production run.  PAE has a lot riding on this yacht and it could become the right model to help bring the next generation of luxury distance-cruising boaters to the brand.  It’s large enough to accommodate truly sumptuous appointments, yet small enough to be easily handled by a couple without crew.

In the table below, you can see that the sweet spot for cruising will be a little more than 8 knots.  The fuel consumption basically doubles from 8.1 knots to 9.30 knots.  And of course, as with nearly every other hull like this, if you slow down you get better range.  Here you can see the NMPG at 7.55 knots is 1.42, which is very good performance for a yacht that displaces about 143,000 lbs.

The N63 hull incorporates an interesting design detail called a “maintenance strake.”  We wrote about it here.

You can download the complete performance data sheet here.

Here is a link to the Nordhavn 63 webpage for full specs and information.

What Would YOU Do With this Nordhavn 63 Helm?

The folks at Pacific Asian Enterprises just recently unloaded N63-01 from its freighter in Miami and brought it up to the Stuart completion center.  It’s a beautiful boat; an evolution of the N55/60 hull with the aft pilothouse and overall look of the venerable N62 (but not quite the beam of that boat).  In looking at the pictures P.A.E. posted on the Nordhavn brand website, I was drooling over the huge blank canvas of a dash in front of the helm and, naturally, I began to fantasize about what I would do if it was mine to outfit.

Take a look at the photo above and imagine your favorite marine electronics installed in that non-glare acreage.  It occurred to me that you could put a 32″ HDTV in that slot and use the latest Picture-in-Picture (PIP) controls to split the screen with whatever secondary input you want.  On the other hand, one large screen like that means a single-point failure is going to be more of a pain in the rear.  So, typical design philosophy says we should split that area into two large displays.

I know I would prefer a black-box solution, with the displays fully customizable and redundant.  If you really want to go the full belt and suspenders route, you could probably put a multifunction chartplotter/display on the far left side of the dash.  In fact, since most owners of yachts this size will have two radars aboard, you could run the secondary radar as part of the chartplotter setup and use the primary radar on the main displays via black-box processor.

In the other photos in this piece, all courtesy of PAE, you can see there is quite a bit of room to spread out and relax in this pilothouse, as well as a beautiful salon and galley below.  Delivery of N63-01 is set for a couple of months from now.  We did a piece a while back on an interesting design feature of the hull of this Nordhavn here on OceanLines.

Nordhavn 63-01 Sits on Her Lines at the Factory in China

P.A.E. today confirmed that hull #1 of the new Nordhavn 63 is in final preparation for shipment from the factory in China to Florida, where it will be commissioned and available for inspection. The N63 is a development of the N55/N60 series, with new deck and engine room molds. With its beam narrower than the N62, it will fit in places the latter cannot.

The N63 is described by PAE as an aft-wheelhouse version of the N60, retaining some of the saltiness of the original N62 but with the narrower beam.  In the accompanying photos, you can see it in the “tank” at the factory in China undergoing its first tests and systems checks. P.A.E. President Dan Streech told me yesterday that they hope to ship the boat by mid-September and have it available for viewing by the end of October.

Boat Design: A “Maintenance Strake” on the Nordhavn 63

We ran a story yesterday with some new photos of the Nordhavn 63 debut hull in construction at the factory in China.  As many of our readers know, part of the Nordhavn “mystique” is a result of the reputation of its full-displacement, bluewater hull designs.  These are the products of PAE’s chief designer Jeff Leishman, younger brother of one of the company’s co-founders and design contributors, Jim Leishman.  Over the years, the basic hull designs have been continually refined and have benefited from tank testing and analysis.  If you look closely at one of the photos from yesterday’s article, which I have marked up here with a black oval and arrow, you will see a somewhat unusual appendage on the bottom of the hull where the keel fairs into the flatter line of the hull bottom.  It looks in this angle to be a kind of bulbous addition to the hull.  Being a reporter and not afraid of my own naiveté, I decided to ask PAE’s Dan Streech about it.

“We call those ‘maintenance strakes’,” says Streech.  “They provide the room inside of the boat to walk around the engine.”  It sounds like an interesting way to add depth to the engine room.  Obviously, it would slightly increase the displacement of the hull, but I wondered how they came up with this idea and what the effect is, hydrodynamically speaking that is.  The answer Streech provided sheds a little light on the nearly unlimited sources of imagination and inspiration of the Leishmans.  According to Streech, “Jeff and Jim conceived and invented those while sitting on a turbo-prop plane and noticing all of the bumps, bulges and nacelles which didn’t seem to prevent the plane from flying.”  Streech adds, “We tank-tested them and actually found a reduction in drag (for reasons which were never fully explained).”

In the photo above, you see a Cessna Caravan, a turbo-prop-powered passenger and utility plane which uses a large faired extension on its fuselage (the “hull” of an airplane) to achieve a similar capacity increase.  Given that the aircraft is not designed for speeds higher than a couple of hundred miles per hour (relatively slow in commercial aviation terms) the drag penalty is negligible.  It would probably be somewhat different if the Caravan were intended to fly supersonically, but that’s a different kettle of fish.

First Photos: Nordhavn 63-01 Hull Complete, Deck Plugs Under Construction

Pacific Asian Enterprises’ President Dan Streech reports that the hull mold for the new N63-01 is complete and workers at the Nordhavn China plant are finishing the deck plugs, after which molding will commence.  In these first photos of the boat under construction, you can see the way the vessel will look when superstructure is completed and mated to the hull.

The N63 is the latest iteration of the N55 hull design, but incorporates the larger cockpit and boat deck of the N60.  PAE has already sold two of the N63s, and this first hull is scheduled to be completed in May 2010.  You can read more of the details of this fourth-generation Nordhavn in our original story about the program launch here.

In the photos with this story, workmen are putting the finishing touches on the wooden plugs for the main and upper deckhouses, including the pilothouse.  Streech reports that interior construction is also well underway.

If all continues to go to plan, the first N63 could be completed less than a year from the time the first order was placed.
