New Artemis 46 Undergoes Seatrials in China

Howard Chen’s Jet Tern Marine has launched a new planing motoryacht line called the “Artemis” with a 46-foot debut model. Jet Tern Marine”s Zhu-Hai, China, shipyard is best known for its Selene line of displacement yachts. According to the company, the new Artemis line was developed “in response to consistent and strong market demand for a high-performance yacht built by Jet Tern.” The company said that, eventually, models from 36 to 66 feet will be developed

The Artemis 46 is a two-stateroom, two-head flybridge motoryacht, powered by twin 380hp diesels from Yanmar and is designed to cruise at a top speed of 23 knots; a performance level verified during sea trials of hull 4603. The yacht has a beam of 14 feet 4 inches, a waterline length of 38 feet 11 inches, and a draft of 3 feet 9 inches. The yacht has a fuel capacity of 400 U.S. gallons, with water and holding tanks of 100 and 50 U.S. gallons, respectively.

The Artemis 46 has walkaround decks, flybridge, and covered cockpit. A sliding door opens to the saloon with a contemporary design and built-in settees with seating for four around an adjustable table. The interior layout is open with the helm station to starboard and the galley down two steps to port.

Jet Tern says the first four yachts have already been sold in China. The company press release downplays it somewhat, but I believe the Chinese market for this type of yacht may represent the best real growth potential in the near future. China has embarked on a program of luxury marina building around the country and is deliberately fostering a yachting culture. I expect to see offerings like the Artemis, perhaps even more upscale, from some interesting sources over the next several months. The base price of a new Artemis 46 is approximately $690,000, including freight and commissioning.

Glacier Bay Adopts Yanmar for Diesel-Electric Base Power

Editor — Fri, 06 Mar 2009 18:27:48 +0000

Glacier Bay Inc., the Union City, California-based energy management technology company, announced recently that it was standardizing on Yanmar diesel engines for its innovative marine diesel-electric system. Early prototypes of the system had been using Mercedes diesels but the switch to Yanmar means boats using the Glacier Bay system will have a huge in-place global support network. Yanmar marine diesels are used all over the world in both recreational and commercial applications. “The industry is yearning for a reliable hybrid propulsion solution that can be easily serviced worldwide,” said Glacier Bay CEO, Marc Hoffman.

The Glacier Bay diesel-electric system is designed to efficiently manage the generation and distribution of electrical power aboard a boat for everything from hotel loads to propulsion. The system places the diesel engine wherever it best suits the boat designer’s weight and balance requirements and connects it to the power system via electrical cables. Glacier Bay developed high-efficiency DC-electric motors which can be coupled with conventional shaft systems or saildrives for powerful, quiet electric propulsion.

In the drawing below, Glacier Bay shows how a typical diesel-electric system might be used aboard a sailing cat for both basic electrical power requirements and propulsion, through the saildrives in each sponson. Notice that the diesel generator, typically the heaviest component of any system, is here placed near the center of gravity, thereby adding to the stability of the boat and simplifying the balance calculations for trim and waterline.

First Leopard 37 Powercat on the Way to U.S.

Leopard Catamarans is preparing the first 37 Powercat for shipment to the United States, following the first hull’s initial sea trials at builder Robertson and Caine, in Cape Town, South Africa. Making the journey aboard a freighter, she is expected to arrive in Baltimore early next month.

OceanLines is the first, as far as we know, to publish photos (see gallery below) of the new 37 Powercat making her initial sea trials off Cape Town last week. The boat will make her public debut in Annapolis and the Trawlerfest at Solomons Island, Maryland in early September.

The Morrelli and Melvin design features two staterooms and two heads, with the traditional roomy catamaran salon between hulls. There is a relatively large main-deck cockpit aft, shaded by the extended flybridge above. The flybridge features a large, centered helm station, with an L-shaped sette behind and a lounger to port. A stairway leads below to the main deck cockpit, through which the salon is entered.

In the salon, the galley is to starboard, with a navigation station to port. A large U-shaped dinette is centered forward, facing aft. The boat is powered by two Yanmar 4JH4-HTE 110 HP engines, with a total of 253 gallons of fuel available in two aluminum fuel tanks. Given the typical fuel efficiency of the catamaran design and the Yanmar diesels, range should be significant, although exact numbers weren’t yet available at press time.

Among the options, are a Northern Lights 6 kW generator and dual-zone air conditioning. The boat displaces approximately 8, 500 pounds and has a fresh water capacity of 113 gallons. A specification chart follows the photo gallery.
