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:

Jet Tern Marine’s Selene Trawler Line Turns 10

Selene 48 Cruising

Selene 48 Cruising

Jet Tern Marine  is celebrating the 10th anniversary of the debut of the Selene line of ocean-class, long-range, full displacement trawlers.  The company has sold more than 300 boats in the line, which now includes boats from 37 feet to 75 feet in length.  Two factories in Guangdong Province in China — at Zhuhai and Dongguan — in the Pearl River Delta provide the company with an experienced craftsman workforce as well as easy access to the sea.  JTM is run by Howard Chen, whose family runs the parent company, Jet Tern, well-known worldwide for its flatware.  Incidentally, Selene includes a customized flatware package with all its new boats — one benefit of the Jet Tern family relationship.

OceanLines talked recently with Selene’s East Coast dealer (except for Florida), Selene Annapolis, which is owned and run by Chuck Wistar and his wife Andrea.  Wistar is a former Selene 53 owner who traveled more than 14,000 miles on their trawler before selling it.  The Wistars had happily worked with Jet Tern Marine while they owned their Selene, showing the boat for the builder at both the Newport and Annapolis shows in 2003.  When Jet Tern Marine’s Howard Chen found out they were selling their boat, he asked them to consider becoming the Selene dealer on the East Coast.

According to Wistar, the 53 and 55 are the “sweet spot” in the Selene line, although the new 59, introduced only 2 1/2 years, “is already on hull number 37 or 38,” said Wistar.  At roughly $1.5 million base price for the boat, it’s an attractive price point in the trawler industry.  Wistar says the 48 is also a popular boat; a two-stateroom alternative to the 53.  “For a couple with only occasional visitors, the 48 is a great boat,” says Wistar.  Recent updates to the molds for the 48 have deepened the hull where it joins the keel.  “This gives you roughly 5 feet, 10 inches of headroom in the engine room” in that boat, he said.

All Selenes are solid fiberglass hulls, up to the waterline; while above that they are cored with Divinyl cell.  Selene uses vinylester resin to laminate the first four layers of the hull, a laminate schedule unmatched anywhere else in the trawler industry, according to Wistar.  The result is that, “to my knowledge, there has never been an osmotic blister on a Selene,” Wistar said.  The corporate confidence in that statement translates to a lifetime warranty against hull blisters, so that’s one less thing to worry about for year-round boaters and liveaboards.

All the Selene models from 43′ upward are raised pilothouse models and all are CE Ocean-A rated.  Selene customers are typical of the trawler market; most either at or nearing retirement and with plans for most to move aboard and live aboard while cruising full-time.

The smaller Selenes have been extremely popular with Great Loop cruisers in the United States.  They have no air draft issues with the Erie Canal, which is a typical stumbling block for some other trawler brands.  “Our air draft, on the 53, even with the KVH (satellite) domes, was just a little over 19 feet,” says Wistar, who, with his wife, took their 53 on a variation of the Great Loop, called the “Down East Circle.”  This cruise of approximately 2,400 miles, takes boaters up the Hudson, across the Erie Canal and Lake Ontario to the headwaters of the St. Lawrence River.  The route proceeds downriver (although still mostly northeastward) through the locks to Montreal, Quebec and out the mouth of the Seaway to the islands of the Canadian Maritimes — Prince Edward Island, Nova Scotia, Newfoundland.  The last leg is across the Bay of Fundy to Maine and down past New Hampshire and Massachusettes to New York.  While the Wistars ran the route in two months, they say they would like to do it again but take an extra month to do some more sightseeing along the way.  Read all about the Wistars’ cruise HERE.

Selene has an active owners group, and a recent East Coast rendezvous attracted 40 owners and 7 boats to Hutchinson Island, Florida, for an event co-hosted by Selene Annapolis and Selene Florida.

We talked more about the 48 as a particularly price-attractive boat in these economically tough times.  Wistar says the basic price, plus a good cruising package of options that would include stabilizers, a/c, hydraulic davit, icemaker, bow and stern thrusters, a big inverter and a hardtop, plus delivery, would run about $896,000; certainly a competitive price for a big-boat trawler these days.

The 48 is a result of customer feedback on the original 47 model.  According to Howard Chen, the designer and builder of the Selene range, “The main 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.”

The 48 also boasts an integral swim platform with a telescopic swim ladder, and beneath this is an 18″ hull extension, creating extra room in the lazarette for storing gear and supplies, and at the same time greater buoyancy to offset the weight of the larger flybridge.”

Selene says the 48 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 315hp diesel turning at a relatively slow 1800 rpm it has a cruise speed of 8.6kts, for a range of 2,000 nm.

The Selene 48, like all Selenes, can be easily customized as far as interior arrangement and decoration.  A typical configuration would feature an offset galley in the salon to starboard, with a settee and hi-lo table built-in to port.  The pilohouse has plenty of room for an L-shape settee and a nice helm chair; some even put a pilot berth in as well.  According to Wistar, the flybridge is a (pun intended) high point, of the brand.  “These boats all have a terrific flybridge, with great sight lines forward and around.  They’ve got built-in settees and lots of room for entertaining,” says Wistar.   The 48 can be ordered with a single or with twin engines.  The singles can have a get-home engine, or a hydraulic get-home run off a generator.
