Nordhavn to Expand Coastal Pilot Series with 59CP

Nordhavn to Expand Coastal Pilot Series with 59CP

Two years after it launched the 52CP, Pacific Asian Enterprises (PAE) has announced a larger addition to the new semi-displacement lineup of Nordhavn yachts — the 59 Coastal Pilot (59CP).  The Coastal Pilot boats are a little more than half the displacement of  a similar full-displacement boat, and sport top speeds up to 20 knots.  PAE says they represent not only a good way for the company to expand the demographics of its high-end customer base, but as transitional boats for people moving into or out of the full-displacement bluewater ocean-crossers that make up the original Nordhavn line.  Jim Leishman, PAE vice president, said, “This is the perfect type of vessel for anyone with dreams of extended cruising that don’t involve ocean crossings — for instance, an Alaska-to-Maine itinerary.”

How is the Coastal Pilot series different?

They are lighter. The 59CP has a design displacement of about 71,000 lbs., which compares to the full-displacement Nordhavn 60 at 130,000 lbs. Obviously, the ocean-crossing N60 needs to carry much more in the way of fuel and other consumables.  To be honest, the two yachts are not really that comparable since the N60 is fully 4′ longer and a foot wider in beam.

They are faster.  It’s probably obvious, but with less hull in the water and with two engines standard, cruising and top speeds are going to be higher.  A full-displacement hull is normally limited in top speed mainly by the length of the hull (longer hulls go faster).  The N59CP will reach about 20 knots at top speed, while an N60 is just about 10 knots.

They are designed for coastal cruising.  A number of factors contribute to this quality.  From the captain’s perspective, draft, speed and range all contribute.  The higher cruise speeds mean more destinations within reach during shorter time spans.  The significantly shallower draft — only 4′ 2″ on the 59CP — mean that much more gunkholing and close-in island anchorages are accessible.  The Bahamas, for example, become much more interesting in a luxury yacht with that kind of shallow draft.  The range (at lower cruising speeds) is up to 1,000 miles.

They are sedan and express cruiser designs.  Nordhavn full-displacement yachts are raised pilothouse designs, intended to provide appropriate isolation from the normal distractions of the living spaces, particularly during night time watches on extended passages. In coastal cruising, however, night passagemaking is much less often a requirement and the single-deck design on the main level means the watchstander can be part of the family dinner discussions.  Here’s a link to the Nordhavn 52CP, the first boat announced in this new Coastal Pilot series.

How are the Coastal Pilot Yachts similar to other Nordhavns?

They are the same quality, which is certainly at least equal to the best in the entire industry.  That includes the substantive areas of mechanical and electrical systems, as well as the cosmetics of furnishings, surfaces, cabinetry and household appliances. Nordhavn mechanical and fuel systems are known for their offshore reliability and simple concepts like a sight glass for the fuel tank demonstrates the safety mindset of the designer.

They are as safe.  The N59CP will carry a “CE – Category A” unlimited offshore rating, which ensures the highest levels of seakeeping and strength.  There isn’t a boatbuilder around that knows more (or maybe even as much) about safe cruising as PAE  In fact, 2014 is the 10th anniversary of the famous “Nordhavn Atlantic Rally (NAR),” which saw a fleet of Nordhavns cross the Atlantic non-stop.

General Configuration

The Nordhavn 59CP is an express-style cruiser with a single main deck that includes the raised aft cockpit, salon, galley and helm area. The design features a roomy flybridge with seating for 12 people and plenty of room on the aft portion for a tender.  The lower deck features a VIP guest stateroom forward and a massive master stateroom amidships. There is a three-stateroom option with twin upper and lower bunks that takes a bit of room away from the master.

Also on the lower level, there is a large utility room at the landing of the stairs from above.  It includes the separate Bosch washer and dryer along with a deep freezer chest.  The main stateroom aft of this landing is isolated from the engine room farther aft by two bulkheads, with the fuel tank in between.  There should be no problem of noise and vibration in the master stateroom emanating from the standard twin Cummins QSM11 diesels.

Island Pilot Launches New IP535

Island Pilot Launches New IP535

Island Pilot is super-sizing its IPS-powered 435 into a new 531/2-foot model. New molds for the 535 have been built at the company’s yard in Zhuhai City, China, and Island Pilot reports that it has two firm orders already for the new yacht. If you really liked the 435 but wished it had a little more room, I think this new-but-familiar hull is going to be your ticket.

While the new hull will provide the extra luxury and roomier accommodations requested by Island Pilot customers, the IP535’s performance capabilities will derive from the latest IPS variant from Volvo Penta — the IPS II 900. The announcement from Island Pilot noted that in addition to three “joystick” docking stations, the IP535 will be fitted with Volvo Penta’s new “Dynamic Positioning System,” which holds heading and position automatically using a GPS array mounted on the radar arch.

On the performance side, here’s what Island Pilot says,

Extensive tank testing plus computer simulations predict a top speed of 33 knots with economical fast-cruising speeds between 18 and 28 knots. At slower speeds, the IP535 will have similar economy to single-screw displacement trawlers and mid-speed, semi-displacement cruisers. The pair of 700hp, D-11 diesels is aft in a walk-in, stand-up, uncluttered engine room accessed through a weather-tight door in the cockpit. The spacious engine room allows easy access to all sides of the engines and generator with room left over for a work bench and tool storage. Other systems normally crowded around the motors are located in an easily-accessed “basement” under the galley sole.

More from the Island Pilot press release:

The IP535’s high-end performance is complimented by her inviting and accommodating cockpit layout, spacious flybridge arrangement, and interior appointments. A 9-foot U-shaped settee is the focal point of the cockpit and with its own canopy the space is perfectly laid out for outdoor entertaining. Owners can select to have a full summer kitchen including grill and wet bar either in the cockpit, on the flybridge, or in both locations. The flybridge has space for three helm chairs or a pair of twins and is outfitted with a pair 15-inch Garmin touchscreens, the same found at the lower helm.

A signature feature of all Island Pilot yachts is the bright, open feeling of the deck house, with plenty of glass and 360-degree vistas. The IP535 continues this tradition with even more space—the U-shaped settee is 11×6 feet—the LED HDTV is 46 inches—and room remains for a pair of barrel easy chairs and the raised helm chairs. At 12×14 feet 6 inches, the deck house is highly customizable. Forward of the deck house, under the great expanse of windscreen, is the “great room” with the fully-equipped galley overlooking the dinette. Forward is an island-queen VIP stateroom and aft, under the deck house, is the full-width, mid-ship, master stateroom. Measuring 11×16 feet, this space can be configured to an owner’s preference and be fitted with an island queen, either angled or squared off, or a pair of twin berths. With her unique layout, the IP535 affords the privacy found in an aft-cabin yacht with the advantages of the sedan-styling. Reuben Trane comments, “The only time at night that owners are likely to even remember that guests are on board is if they all choose the same time to raid the fridge!”

Grand Banks Launches New 55 Aleutian RP Yacht

Current 59 Aleutian RP from Grand Banks - New 55 Aleutian RP Has Similar Profile

Current 59 Aleutian RP from Grand Banks - New 55 Aleutian RP Has Similar Profile

An e-mail from Grand Banks last week to current and prospective customers invited them to a private micro website which reveals the existence and details of a new junior member of the Aleutian raised pilothouse series of yachts the company is building.  The new 55 Aleutian RP is intended to offer “outstanding long-range capability,” according to an overview of the new yacht on the website.

The new 55 Aleutian RP is not simply a smaller 59, according to Grand Banks, although in renderings it retains all the classic lines of the Aleutian models.  The company says it did a complete re-evaluation of everything from hull design to layouts and made a number of changes as a result, including a new three-cabin layout, and a redesigned engine room with significantly more space.  The website shows video of  a hull model of the new 55 being tank-tested under various simulated sea-states and speeds at the University of Michigan in Ann Arbor.  Grand Banks says it also built full-size, walk-through mockups to validate the new layouts and storage areas.

The website was noticeably vague on propulsion details, although one section notes the yacht will be outfted with -blade props from ZF, measuing 34 inches in diameter by 31 inches in pitch, and tuned to S-class tolerances.  The boat will also be equipped with Delta T™ Air Demisters and a full Fireboy automatic fire suppression system with automatic engine, generator and ventilation shutdown.

When asked for artist’s renderings for this article, a Grand Banks representative said the company was not ready for a full-blown media launch but would start advertising in October.  It seemed clear from the website information that the first hull was already under construction but that could not be confirmed by press time.  As we find out more about this boat, you will see and read about it here on OceanLines.  In the meantime, here are the basic specifications of the new Grand Banks 55 Aleutian RP as provided in the preview website.
