ISA Building Hybrid-Powered ISA 140 Megayacht

ISA- 140_1

Come next summer, ISA plans to deliver this 140-foot (43.63-meter) megayacht, its first featuring all-fiberglass construction as well as a hybrid propulsion system developed by Siemens.

There are several well-known benefits to hybrid propulsion, such as lower fuel burn, quieter atmosphere onboard, and lower emissions, without compromising speed or performance. Hybrid propulsion can involve batteries and/or gensets in addition to traditional diesel engines. For the ISA 140, ISA has selected two gensets powering electric motors in addition to the diesels, each set of which can operate with a single pair of Rolls Royce waterjets. For times when the owner wishes to travel close to the anticipated 32-knot top end and 26-knot cruise, the ISA 140 megayacht will operate solely on traditional power. For maneuvering slowly, up to 8 knots, the captain will engage the electric motors. Of course, the hybrid system also serves as a redundant source of propulsion, should something go wrong. The shaft gensets for the electric motors can turn the props if the main engines fail.


If the owner is particularly concerned about fuel consumption, or the megayacht is in an environmentally sensitive area, it’s easy to imagine the electric motors will be used often. ISA expects a fuel burn of only 2.9 gallons per hour (11 liters per hour) at 8 knots when they are the sole source of propulsion. ISA also expects fuel consumption at the best cruise under diesel power to be miserly, just 23.78 gallons per hour (90 liters per hour) and range to be 2,600 nautical miles.

While full details on the interior design aren’t available yet, the five-stateroom layout of the ISA 140 will be designed by Nuvolari-Lenard. Expect customary indoor and outdoor spaces like a saloon, sundeck, and beach club (above).

On a related note, this isn’t the first time a megayacht builder—ISA included—has collaborated with Siemens. Kingship, Wally, and Wider Yachts have all either launched or plan construction on megayachts featuring Siemens hybrid systems. While it hasn’t built a megayacht with Siemens yet, Trinity Yachts is more than familiar with the offerings, as its sister company, TY Offshore, has worked with Siemens on commercial and/or military vessels. As for ISA, it aimed for zero emissions in presenting the ISA 390 Zero concept back in 2009.

Palmer Johnson Launches 210 Sport Yacht Lady M

The weather on Friday may have been dreary, but the mood was anything but at Palmer Johnson, because that’s the day its largest megayacht to date, a 210 Sport Yacht christened Lady M, rolled out of her build shed in preparation for her launch, which took place Saturday.

The all-aluminum 210 Sport Yacht, so-named for her 210-foot (64-meter) LOA, was fully designed by Nuvolari-Lenard, both outside and in. Aficionados will no doubt recognize their signature styling elements. No photos are yet available of Lady M’s interior, but it does include five staterooms and a joinery job that the design team calls “fantastic.” To get an idea of what the megayacht’s layout looks like, initial illustrations showcase a fold-down balcony off the master suite, plus an overall emphasis on big, casual yet chic relaxation areas. It’s interesting to note that, on its Facebook page, Nuvolari-Lenard says, “this officially is our best design ever. Alfa Nero was a queen for the last 4 years, it was about time for a new princess.”

It’s also worth noting that the movement of the trideck Lady M was a tricky situation. Power and phone lines were alongside the route the 210 Sport Yacht needed to take to get to the launch area, and her beamy nature (31 feet, or 9.5 meters), necessitated tapping the assistance of utility crews. In addition, due to those wires and the overall height of her build shed, the navigation mast could not be put in place until the 210 Sport Yacht slipped into the water.

Sea trials will be conducted through the rest of the month, after which Lady M will be prepared for final hand-over. Thanks to 9,000 hp generated by twin 16V 4000 series MTU engines, cruise speed should be 24 knots and top speed should be 28 knots.

Quattroelle Delivered by Lürssen (VIDEO)

The 282’5″ (86.11-meter) Quattroelle, the first Lürssen yacht to be designed by Nuvolari-Lenard, was handed over to her owners this past weekend. The video below shows the megayacht making her way along the Kiel Canal in Germany, prior to the official delivery.

Nuvolari-Lenard didn’t just pen the megayacht’s exterior lines or her classic interior. The design team was responsible for everything from the look of the tenders to Quattroelle’s crew uniforms. But, in reference to the megayacht, Dan Lenard of Nuvolari-Lenard explains, “As we drew the lines, we kept two things in mind. Firstly, we wanted the yacht to be truly Italian in her styling. So we gave her an aggressive yet streamlined look that still manages to be elegant. Secondly, we wanted to make sure her external appearance reflected a timeless heritage and reflected the best engineering practices available at the builder’s yard in Germany.” Nuvolari-Lenard further ensured a good deal of alfresco space was available for dining, relaxing, and entertaining, a directive from the owner.

Quattroelle is available for charter in the Caribbean, where she’s expected to head soon, and the Mediterranean this summer. In case you’re wondering why she’s named Quattroelle, it’s in honor of what the owner, who has more than a decade of experience owning large yachts and megayachts, considers the four Ls: Love, Life, Liberty, and Luxury.


Lürssen’s Quatroelle: Designer Commentary by Nuvolari-Lenard

Delivered this month after extensive sea trials in October, the 282’5″ (86.11-meter) Quattroelle is the first Lürssen yacht to be designed by Nuvolari-Lenard. The Italian design team of Dan Lenard and Carlo Nuvolari was responsible for both exterior styling and interior design. Sold and supervised by the technical team of Moran Yacht & Ship, the megayacht, as you may recall, was originally known only as Project Bellissimo. Quattroelle essentially means “four Ls,” these being Love, Life, Liberty, and Luxury.

Nuvolari-Lenard’s partners give us some insight into this challenging project. Due to her size (beam is 45’3”, or 13.8 meters) and her massive volume, the test became to keep her sleek and proportionate.

“It was an exciting project,” says Lenard. “This large yacht is one of our most detailed designs ever. We started with a blank sheet of paper and designed both the interior and the exterior. The owner is well known to us and trusts that we understand what he wants to achieve. We have tailored the design to precisely suit his personality, and we have no doubt that when he looks at this yacht he sees himself reflected in what we have designed. She is more ship than yacht, and as we drew the lines, we kept two things in mind. Firstly, we wanted the yacht to be truly Italian in her styling. So we gave her an aggressive yet streamlined look that still manages to be elegant. Secondly, we wanted to make sure her external appearance reflected a timeless heritage and reflected the best engineering practices available at the builder’s yard in Germany.”

“One good example of what we mean is the tri-dimensional shape of the sheerline amidships,” Lenard continues. It enhances the ‘power’ of the hull at the same time as introducing a styling detail of the superstructure.”

Lenard also says that the owner wanted Quattroelle to have plenty of exterior space devoted to leisure. “To make sure he always had the opportunity of using it, we designed the after end of the upper deck so that it could be closed in, using glass panels that slide and pivot into place easily,” Lenard explains. “By doing that, we have made the space far more flexible. In warm weather it is always open, but move northwards, and there are times when the evenings can become a little chilly. In keeping with the supply of plenty of exterior space, we have made the huge foredeck user-friendly and have built a terrazzo around the large swimming pool.”

In terms of the interior, Nuvolari adds, “Beautiful woods dominate the interior decor but never overpower the senses. It is not so much a classic interior but a modern approach to a classic feel. We think the finished result is rich and sophisticated and just as importantly is neither excessive nor vulgar.”

“The detailing is what makes the interior special,” he continues. “Take, for example the use of Murano glass in the chandelier above the dining room table, or the bronze railing of the main lobby stairs. They are both in their own special way true pieces of art perfectly created.”

Interesting enough, Nuvolari-Lenard’s involvement with Quattroelle’s design didn’t end with the styling or interior. “We designed everything from crew uniforms to the two large tenders the yacht carries,” Nuvolari says. “One of those is a classic limousine tender, and the other a sleek walk-around model. We designed them both on the same hull line using the same engines. That way they can be carried on either the port or starboard side because they each share a common cradle requirement, and what is more, the engineer need only carry spares for one type of engine.”

Moran Yachts, which wrote the technical specifications for Quattroelle and represented the owner both before and during construction, has a long relationship with this client. “We have represented the owner of Quattroelle for over 14 years, having sold to him his previous yacht, the motoryacht Capri, and represented him with the sale of several of his previous yachts,” Robert Moran, CEO of Moran Yachts, explains. “This client, being very familiar with the operations of large yachts, had a very explicit brief for what he wanted with his new custom yacht.” After discussing the project with several shipyards, Moran adds, the owner selected Lürssen. Moran also says that Quattroelle’s captain, Paul Bell, and chief engineer, Robert Miller, were involved in many aspects.

Quattroelle is now available for charter, as part of the central agency of Moran Yacht & Ship. Her rate is €1 million per week, plus expenses. She already has 12 weeks booked for the upcoming Caribbean and the Mediterranean season.

2 Nuvolari-Lenard Megayachts Underway at Palmer Johnson

Thanks to Nuvolari-Lenard, we’re getting sneak peeks at two megayachts presently under construction at Palmer Johnson.

The design studio shares updates on several of its projects on a regular basis on its Facebook page, and these Palmer Johnson megayachts are among the updates this week. The megayacht pictured above is one of the PJ210s, a.k.a. 210-footers, the shipyard is building, code named Project Stimulus and Project Hermes. The all-aluminum PJ 210 is the largest Sport Yacht in Palmer Johnson’s history, and its largest-ever megayacht period. In fact, the PJ 210 is the largest yacht to be constructed in Palmer Johnson’s home state of Wisconsin. Interior renderings reveal fold-down balconies will be to each side of the dining area. Another fold-down balcony forward in the main-deck owner’s suite will make a nice terrace, too. There’s further a good deal of alfresco space, in keeping with the Sport Yacht theme, including a terrific crow’s nest complete with seating. Delivery is set for next year.

As for this megayacht, she’s slightly smaller, at 171 feet LOA. Nuvolari-Lenard describes her as a sistership to DB 9, still bearing the Sport Yacht styling and emphasis on alfresco enjoyment. Though, there is a difference. This time, the yacht will have a closed upper deck between the mast wings, which were not yet in place when the photo was taken recently.

We’ll have more updates in the coming months.
