New Nordic Tugs 39 A Nice Update to NT Fleet

New Nordic Tugs 39

New Nordic Tugs 39

In a piece I wrote for YachtWorld.com this week, I said that the new Nordic Tugs 39, an updated replacement for the NT-37, is a worthy successor.  The couple I interviewed in the story, Donna and Kevin Steele, went through a meticulous process that culminated in choosing the new NT-39 and their experience would serve any new boat buyer well.  Have a look at the piece on YachtWorld.com.

Video – Wilbur 46 Launched, Cool Green Features

The New Wilbur 46 from Maine Boatbuilder Wilbur Yachts

The New Wilbur 46 from Maine Boatbuilder Wilbur Yachts

Wilbur Boats, the Maine custom yacht builder, has launched Betsy, a Wilbur 46 that brings together classic design elements of Downeast lobster boats, with some of the most advanced green energy technology available.

With a crossover-type hull that can be driven efficiently at both displacement speeds and plane at 27 knots, the Wilbur 46 you see here has a Caterpillar C-18 diesel with 1,015 hp for main propulsion. The yacht also incorporates solar panels and a fuel cell to replenish batteries. Fuel cells are often considered one of the Holy Grail clean power technologies but are still extremely rare aboard boats.  Maine Boats, Homes & Harbors magazine has a nice story about the launching here.

Layout Details of the New Nordhavn 78

P.A.E. has released preliminary layout details for its new Nordhavn 78 long-range motoryacht.  The plans reveal a focus on outside entertaining and roomy berthing spaces. Clicking on the drawing above will open a larger view that can be magnified somewhat to show more detail.

The plans show a spacious owner’s cabin just forward of amidships and oriented fore-and-aft. A sitting area to port and a desk to starboard are complemented by a large head aft and to port, with a walk-in dressing area aft and to starboard. A guest stateroom is farther aft and features twin berths, a spacious head and storage closet. A dedicated laundry room is also on the same aft level.

The main guest stateroom is forward, accessed down a stairway from the pilothouse and features lots of storage and a head between it and the owner’s suite aft (let’s specify extra sound insulation in that bulkhead). The guest suit also has room to port for a small desk or dressing table.

For the crew, there is a captain’s cabin, with a small head in the aft end of the pilothouse; the main quarters being all the way aft, entered normally through a transom door, but also accessible through a hatch in the aft end of the engine room. Another door at the forward end of the engine room leads to the smaller guest suite and laundry room.

The nominal layout for the saloon shows a dining table for eight to port, with sofa and two chairs to starboard. The galley is forward and to port and puts the stove on the large, aft-facing counter, with a raised counter above it and three bar stools on the other side for informal dining or conversation with the chef. The aft cockpit looks roomy and uncluttered, with a long bench along the curved transom with a table in front of it for dining. Curved steps lead down to the swim platform from both corners of the transom.

Up a few steps forward into the pilothouse and you come into a large, comfortable-looking space. Twin helm chairs, with the main instrument panel and controls on the left side and complemented by a large desk/chart space to port and a huge, u-shaped settee and table aft. Sliding doors on either side of the pilothouse lead to wide walkways, which can be followed forward to a large sunpad on the forward deckhouse.

The flybridge is accessed from a starboard stairwell in the pilothouse. There are twin helm chairs forward and to port, and a circular table and chairs behind that. To starboard is an outdoor galley and curved bar. Aft are the Jacuzzi to port and an L-shape settee to starboard. The boat deck is all the way aft and this drawing shows a davit to port and a moderately large Nautica center-console RIB tied down athwartships.

As with most Nordhavns in this size, there is likely to be plenty of flexibility for owners to customize the layouts, particularly on the main deck.

Selene Goes With Deep-Hull Mod for Entire Fleet

Selene 53DH Hull Mold

Selene 53DH Hull Mold

A series of recent design changes to a small number of the Selene models, including the 53, which we wrote about here on OceanLines, will now be standard on all new Selenes, according to an announcement last week from Howard Chen at Jet-Tern Marine, the parent company of the Selene brand of trawlers.  In addition to some of the larger models that have already incorporated the new design, new 2010 Selene 38, 42 and 49 models are already in production.

According to Jet Tern, “The foundation of the new generation of Selene Ocean Trawlers is a hull design that turns the chines inward to the keel deeper in the water than earlier designs. In addition, all of the next generation molds feature the “cruiser stern” as standard.”  The company listed the following benefits and implications of the design changes:

  • Without changing the draft, headroom in the engine room is increased by a foot or more. Some of this increased headroom is carried into the lazarette.
  • Each new mold is 1-2’ longer than its predecessor. This fact plus the added length of the cruiser stern increase the waterline length resulting in slightly greater hull speed.
  • Greater headroom permits fuel tanks of the same capacity to be higher but narrower, increasing the effective area in the engine room for improved access, storage, and usability.
  • Engines are mounted relatively lower in the hull. This results in a flatter angle of the shaft, and therefore more efficient transmission of power to the propeller.
  • A prop tunnel is now molded in to the hull, further enabling a flatter propulsion angle and the resultant improvement in efficiency and performance.
  • Test tank results indicate the cruiser stern is 7%-8% more efficient through the water than traditional transoms. Some mechanical loss always must be accepted, but this efficiency could translate into 4%-5% improvement in fuel consumption at a given speed.
  • The cruiser stern, with its curved sides and bottom dissipates following seas for improved seakeeping in those conditions.

Of the three smaller 2010 models in production, the new Selene 38 and Selene 42, each with the cruiser stern, evolved from the popular double-cabin layouts of their first-generation counterparts. With LOAs of almost 42’ and 45’ respectively, the yachts are “proven and dependable,” according to Jet Tern.

The Selene 49 is a “next generation” evolution of the very popular Selene 48 model.  It features the new “deep hull” design with its cruiser stern, 10” increase in engine room headroom, and the larger, standard Cummins QSL 9.0 330 hp engine.   LOA is over a foot longer.  On the interior, that also translates to an 8” increase in the cockpit and 4” more in the salon.

According to Chen, the designer and builder of the Selene range, “Another significant difference is a wider body flybridge giving space for entertaining friends and family with style in the open air. This new flybridge layout incorporates an ‘L’ settee and table to one side, a bar/sink/BBQ unit on the other, and behind, ample room for a substantial dinghy and hydraulic crane.”

Jet Tern said the Selene 49 is still an excellent long range cruising boat with a D/L ratio at full load of 316, and A/B ratio at full load of 2.54.  With the standard Cummins at 1800 rpm it has a cruise speed of 8.6 kts for a range of 2,000 nm.  The company considers the 49 to be the flagship of the smaller end of the Selene fleet, intended to incorporate some of the room and luxury of the larger models in a package both affordable and easily handled by a couple.

Jet Tern now has four dealers in the U.S. for its Selene trawlers:
