EXTERIOR DESIGN

As with ALVA Yachts’ existing models in the ECO range, the 78 has been designed with responsible yachting at its core. Its expansive roof has been specifically conceived for its integrated solar panels, giving her a transatlantic range and virtually unlimited autonomy, as the panels take energy from the sun and store it in the battery packs that power the electric engines.

Access to the water is easy from her twin bathing platforms. From bow to stern, this remarkable 12m beamed catamaran offers impressive space, modern style and stable sailing.

Design Process

The 78 benefits from a generous master suite, complete with ensuite and separate walk-in wardrobe. Completing the starboard side is an additional double guest cabin with ensuite.

Further guest accommodation is located within the portside hull and features a double room and twin room with plenty of storage space and both offer ensuite double shower facilities.

The lower deck is complete with twin drop down terraces providing sunbathing options on both sides of the yacht.

ALVA Yachts reveals electric Ocean Eco 78

German yard ALVA Yachts has introduced a new addition to its range of environmentally responsible electric catamarans. The Ocean Eco 78 is a 23.7-metre multihull yacht that features electric propulsion and transatlantic range.

Based on the Ocean Eco 60, the Ocean Eco 78 "offers everything the 60 does but on a larger scale," says Milan Henn, Head of Design at ALVA Yachts.

A beam of 12 metres gives owners and guests plenty of space, while twin bathing platforms offer easy access to the water.

The lower deck is the main spot for socialising and features U-shaped seating for eight guests and twin drop-down terraces to catch the sun on both sides of the yacht. Additional seating and sunbathing spaces can be found on the foredeck, featuring oversized sunbeds and refrigeration options, and at the helm.

Inside, there's a spacious saloon, a generous galley with a bar, and a large master suite featuring an ensuite and walk-in wardrobe. Guest accommodation includes a double guest cabin on the starboard side and a double and twin room to port. All have ensuites.

The interior features a "new-found design direction and material selection" comprising textural layers and a mix of furnishings and fabrics that give a timeless feel with a modern twist. The styling is semi-customisable and owners can choose between five moods: Mountain, Forest, Desert, Dune and Sea.

The yacht's large roof is integrated with solar panels that collect energy to power the electric engines, giving her transatlantic range and "virtually unlimited autonomy". The launch is the next step in ALVA Yachts' mission to promote responsible yachting.

“The new Ocean Eco 78 was created as the perfect addition to our existing range, and sits between the Ocean Eco 60 and 90 models providing owners with a generous increase in size from the 60 but removing the need for crew on the 90," said Henn.

Alva yachts has revealed new, stunning images of the ocean eco 90 interiors.

New renderings of the interiors show huge spaces ansd understated luxury. Ocean Eco 90 has been developed by Alva Yachts and HENN Design.

You can see the renderings in our gallery on top of the page: plenty of images ofthe main saloon and the owner’s apartment. Below is our article about Alva Ocean Eco 90, written at the time of her launch in July 2020.

Alva Yachts introduces Ocean Eco 90 all-electric catamaran

The 27M solar catamaran Ocean Eco 90 will be ready by the last quarter of 2021 and will have virtually unlimited range. Engineers and technicians at Alva Yachts are completing the molds for hull and superstructure.

Alva Yachts, German builder of electric catamarans and sail boats, has just announced the introduction of Ocean Eco 90 by Henndesign, a 27M multi-hull yacht with electric propulsion and (claimed) transatlantic range. The model fits the brand’s philosophy, which has sustainability at the heart of their yachts, both motor and sail. Differently to other electric boat brands, Alva Yachts models are designed specifically around electric propulsion, not retrofitted.

The (electric) journey has started

At the end of June 2020, the project of Ocean Eco 90 is completed and the technical specifications are defined. Construction has begun with the molds for the hull and the superstructure, while the yacht will touch the water by the last quarter of next year.

Ocean Eco 90 is a 27.50 meter long catamaran, with an impressive beam of 14 meters, with a hull made for the range of speed of green cruising, which is not about the thrill of speed but rather about enjoying the voyage. She will available with hybrid or fully electric powertrain. The design is by Milan and Holger Henn of the German Studio HENNDESIGN and the Hamburg based naval-engineering studio iYACHTS .

The superstructure is covered with over 200 square meters of solar panels, giving her a transatlantic range and, under right circumstances, a virtually unlimited autonomy, as the panels take the energy from the sun and store it in the battery packs that power the electric engines.

The hybrid version has two 250 kW electric drives and two 456 kW diesel engines, which also replace the conventional diesel generator.

In the full-electric variant, Ocean Eco 90 is pushed by two 500kW electric drives, connected to a 360 kW/h battery pack, which is powered by sun and generators. The solar panels reach 40 kWp (kiloWatt peak), allegedly much more than the best competitors, while the diesel generators produce 100 kW / DC each.

An even cleaner option is available: the diesel generators can be replaced by two hydrogen-fuel cell ones, and according to the shipyard this makes Ocean Eco 90 the first solar catamaran in this range without the additional aid of fossil fuels.

In both cases, the range in only-electric mode (generators off, power coming from the batteries) can reach 60 nautical miles, a good distance for exploring the most recessed and wild parts of the earth, even restricted marine reserves. All of this, in silence, enjoying the sound of the nature and without disturbing the sea fauna.

Ocean Eco 90 by Henndesign has been shortlisted for “Concept Under 40 Meters Award” in The International Yacht & Aviation Awards 2020.

While the process of construction is well underway, the first unit will be launched by the last quarter of 2021. Manufacturing is fully European, with hull and superstructure built in Antalya, Turkey, and interior and finishing made in Germany.

ALVA Yachts introduces new 78-foot solar electric catamaran with ‘transatlantic range’

Luxury electric boatbuilder ALVA Yachts is back with its latest solar electric catamaran. The upcoming OCEAN ECO 78 will arrive as a mid-size marine vessel in ALVA’s current lineup and comes equipped with the solar and electric propulsion technology to reach a top speed of 14-15 knots (16-17 mph) at sea, plus plenty of battery capacity to go far – all backed by solar panels on its roof.

ALVA Yachts is a German company founded in 2020 by Mathias May and Holger Henn, evolving out of PICA yachts, which was originally founded back in 2013. In that time, ALVA’s predecessor launched over forty 20-30 foot sailing and electric powerboats.

As the brand looks to create the next generation of electric yachts, it remains quite aware of the issues facing marine electrification as well as its own hurdles in developing its zero emission technologies. Its current solution is a growing lineup of solar electric catamarans that are as luxurious as they are sustainable.

The past three years, ALVA Yachts has introduced a 50-foot cruiser, two electric sailboats in lengths of 72- and 82-feet, plus 60- and 90-foot all-electric yachts, including the OCEAN ECO 60, which debuted in 2022 and is now in production.

Today ALVA Yachts has introduced a new 78-foot solar electric catamaran that will fit nicely between the OCEAN ECO 60 and OCEAN ECO 90 .

ALVA Yachts ‘launches’ its latest solar electric boat

The sustainable boatbuilder unveiled the OCEAN ECO 78 in a press release today – a multihull yachts that measures in at 23.7 meters, features a fully-electric drive system, and offers the ability to gain additional power from the Sun, even while navigating the sea.

The fully-electric version of the OCEAN ECO 78 is propelled by two 217 kW electric motors that are powered by massive battery capacity ranging between 280-490 kWh. The large roof of integrated solar panels allows for 26 kilowatt-peak (kWp), which ALVA Yachts states is best in class compared to the 78’s competitors.

By combining large battery capacity and solar integration, ALVA Yachts states the upcoming OCEAN ECO 78 will offer transatlantic range and “virtually unlimited autonomy” with the help of the Sun. From bow to stern, the solar electric catamaran is strengthened by 12-meter beams, another best in class design according to its makers. ALVA’s head of design Milan Henn spoke to the boatbuilder’s latest entry in responsible yachting:

The new OCEAN ECO 78 was created as the perfect addition to our existing range, and sits between the OCEAN ECO 60 and 90 models providing owners with a generous increase in size from the 60 but removing the need for crew on the 90. This new model offers everything the 60 does but on a larger scale.

Other features include twin bathing platforms for easy access to the water, a lower deck with seating for eight, an enclosed saloon, and galley complete with a full size fridge/freezer and island bar with stools. Moving to starboard, OCEAN ECO 78 owners can entertain at a large dining table for eight or at it’s L-shaped obervation area near the helm.

Accommodations include a master suite with a walk in wardrobe, a double guest cabin with ensuite, plus further guest spaces to the portside hull, including double and twin rooms with showers. Like all ALVA Yachts, customers can choose from one of five moods for their interior, including Mountain, Forest, Desert, Dune and Sea. We are awaiting additional details such as the yacht’s estimated range, pricing, and production timeline, but when the OCEAN ECO 78 does arrive, it looks to be another impressive entry in solar electric catamarans. Per ALVA Yachts:

ALVA Yachts is bringing yachting into a new era with electrified solar catamarans and sailing yachts that combine self-sufficient, long-range cruising capabilities and class-leading design, delivering the best boats for forward-thinking explorers.

For superyacht shoppers, the Palm Beach International Boat Show, kicking off its four-day run this week, is set to break records with more than 60 yachts over 100 feet long on display. Last year was also a banner year for superyachts at the show. 

Headliners will include the likes of the 295-foot Corsair Nero ,  the 278-foot Victorious by AKYacht, the 230-foot Turquoise-built Talisman C , and 213-foot Benetti Triumph among brokerage yachts, and in new yachts, the 113-foot Ocean Alexander Puro 35 is making its world debut.  

There are so many gleaming white vessels over 100 feet, in fact, that the fleet will be split between the Palm Harbor Marina at the main show site on the downtown West Palm Beach waterfront and the Safe Harbor Rybovich Marina two miles north. 

Now in its 42nd year, PBIBS will also showcase hundreds of models of dayboats, cruisers, and fishing boats, as well as marine accessories. Running from this Thursday through Sunday, the show coincides with the Palm Beach Modern + Contemporary art show, a fortuitous opportunity for yacht owners wanting to add new art to their collections.

Here are 10 must-see boats at this year’s show.

Corsair Yachts ‘Nero’

The undisputed star of this year’s Palm Beach show? That would be the 295-foot, classically styled superyacht Nero , built in 2007 and inspired by American financier J.P. Morgan’s legendary 1930s steamer Corsair IV . Nero ‘s attendance at PBIBS marks its return to the charter market after an extensive refit in 2021. Now better than new, the boat is being managed by Burgess. With weekly charter rates from $497,000, the vessel offers five-star accommodations for 12 guests in six cabins, with pampering from a crew of 20. Part of the refit included a full interior refresh by Italian interior designer Laura Pomponi, plus a major focus on wellness. That meant the construction of a new, state-of-the-art gym and spa, the assistance of a certified onboard trainer, a masseuse and beautician. After PBIBS, Nero will spend the winter in the Caribbean before returning to the Med for the summer season.

Ocean Alexander Puro 35P

Ocean Alexander is debuting the first of its new Puro superyacht series at PBIBS. The 113-foot Puro 35P comes from the drawing board of Italian designer Giorgio M. Cassetta and is a step back from the polarizing lines of OA’s recent Revolution and Explorer series with their bold, vertical bow designs. Aimed at long-distance cruising, the 35P can carry over 5,000 gallons of fuel and is powered by twin 2,000 hp MAN V12s for a 24-knot top speed. Twin 55kW Kohler generators can also keep the yacht powered at anchor for long periods. Other standout features include extensive glazing in the chiseled fiberglass hull, a forward deck plunge pool, and spacious accommodations for 10 guests. 

Think of it as the “starter” Sirena. Aimed at a younger demographic, the Turkish builder’s brand-new Sirena 48 is making its U.S. debut at PBIBS after a global reveal at last fall’s Cannes boat show. Such is its appeal that 27 hulls have already been sold, with 13 of the orders coming from North America. Looking like a scaled-down version of Sirena’s popular 58, its distinctive, trawler-style lines are from Argentinian designer Germán Frers. With more interior space than a typical 48-footer, the yacht offers three staterooms—plus a crew cabin—a spacious, light-filled salon, a large cockpit, an oversized flybridge, and a vast forward social area. Take your pick from twin 550 hp Cummins QSB, or 670 hp Volvo D11 turbo diesels. Or the builder is also offering hybrid power with twin 285 hp electric motors charged up by variable-speed generators that are good for a 30-mile battery-only range.

Feadship ‘Olympus’

Picture purchasing a classic 180-foot Feadship superyacht, and then getting a $10 million bill for a major refit. That was the case with Olympus , built by the Dutch masters at Feadship in 1996 to a design by Britain’s Andrew Winch and the celebrated naval architect Frits De Voogt. Sold in 2022, the new owner sent it to the Monaco Marine refit center in La Ciotat, France for a major makeover. It included overhauling the 2,600 hp Caterpillar engines and generators, repairs to the structure, substantial upgrades to the guest areas and crew quarters, and new paint throughout. With the work completed just last year, the vessel is said to be in mint condition. Offered jointly by brokers Fraser and Edmiston, Olympus has an asking price of $28.5 million. With accommodations for 16 guests in eight cabins, the boat’s highlights include two primary suites, tropical-spec air conditioning, and Palm Beach-chic decor.

Benetti ‘Triumph’

Italian yachting powerhouse Benetti is showing off its superyacht-building skills with the 213-foot Triumph . Delivered in 2021, this Giorgio M. Cassetta-designed steel-and-aluminum world girder features six decks, a 1,400-square-foot primary suite with outdoor terrace and adjoining lounge, a 750-square-foot beach club, and a touch-and-go helipad. What sets Triumph apart, however, is its lavish interior furnishings put together by the owner along with Benetti Interior Style and Monaco-based Green & Mingarelli Design. It includes pieces by French glassmaker Lalique, marble from Marfil, Statuario and Armani, furs, silk and wool carpets, plus a collection of cool black-and-white wildlife photographs by British fine art photographer David Yarrow. The pièce de résistance? That would be the owner’s Triumph Bonneville motorcycle displayed in the salon.

Fjord 39 XP/XL

Germany’s Fjord Yachts, part of the Hanse Group, has a new 39-foot day boat that it’s unveiling at the Palm Beach show. The 39 XP and XL keep all the bold design cues of the bigger Fjord 41 XP and XL, like a big, open cockpit, walkaround center console, vertical bow, mile-high windshield and stretched hardtop. As for the differences between the XP and XL, it’s all about power. The XL comes with a choice of twin 320hp Volvo D4 diesels, or bigger 440 hp D6 versions, both with Volvo stern drives. Likely more appealing to U.S. buyers will be the XP powered by twin 400 hp Mercury Verado V10 outboards giving a 50-knot top speed. Pricing starts at around $500,000.

Turquoise ‘Talisman C’

Chandeliers don’t come more dramatic than this. Cascading down the central spiral staircase of the Turkish-built, 231-foot superyacht Talisman C , this jaw-dropping piece of art comprises an array of multi-colored glass balls threaded on stainless-steel rods and illuminated by hanging fiber-optic strands. It’s the creation of Prague-based Crystal Caviar and is one of a number of glass installations on this sleek, low-profile superyacht. Built in 2011 by the Proteksan Turquoise shipyard, Talisman C was designed inside and out by London-based studio H2 Yacht Design, with naval architecture by Italy’s Hydro Tec. With cabins for 12 guests, one of its highlights is a huge primary suite, which boasts more crystal chandeliers and a private library. Twin 2,447 hp Caterpillar diesels give a top speed of 18 knots and a transatlantic range of 7,000 nautical miles at 12 knots. It’s listed with Burgess for $59.9 million. 

Sanlorenzo 44 ‘Kamakasa’

Delivered in 2020 and sold to a new buyer just last August, the 146-foot Sanlorenzo 44 Alloy Kamakasa will be for sale at PBIBS. The asking price, through the Italian Yacht Group, is $23.75 million. Lack of use might also be the issue here; the yacht’s twin 2,600 hp MTU V16 diesels have a mere 289 hours on the clock. Built in aluminum to a design by Rome-based Zuccon International Project, Kamakasa was the second hull in the Sanlorenzo 44 Alloy series. One of the top features is a primary suite that spans three levels and almost 1,600 square feet; it also comes with a private Jacuzzi, separate bathrooms, a walk-in closet, and a private study. The yacht’s lightweight construction and MTU power combine to deliver an impressive 20-knot top speed.

Bahama 41 GT2

As ultimate, reel-’em-in, fishing center consoles go, the Bahama 41 from West Palm Beach-based Bahama Boat Works is as hard-core as they come. But when owners kept asking for a little more comfort for the family, the builder responded. The result is the brand-new flagship 41 GT debuting at PBIBS. While the proven, wave-slicing hull stays the same, the cockpit layout is new. In place of the single bench seat, there are now three-across bucket seats with a second row behind. The wider console now has space for a pair of 22-inch Garmin screens, while the new extended hardtop features sun shades and even a rain shower. Outboard choices stay the same with either twin Mercury V12 600s, or four 400 hp Mercury V10s, good for a 65-knot-plus top speed. Pricing is from around $920,000.

Heesen ‘Book Ends’

Launched in 2022, this 164-foot Heesen is part of the Book Ends collection, owned by an American couple who have had more than 18 yachts with the same name. The exterior design of this Heesen was by Omega Architects, while Dutch studio Van Oossanen did the naval architecture. The yacht is part of Heesen’s fast cruising series, which is more efficient than other vessels its size, and can reach 23 knots at full speed with its MTU 16V 4000 M65L engines. The yacht is listed through Ocean Independence for 42 million Euro, or about $45.7 million.

12 months of record ocean heat has scientists puzzled and concerned

Every day for the last 12 months, the world’s sea surface temperatures have broken records.

Ocean scientists are growing increasingly concerned. 

“It’s not just an entire year of record-breaking ocean temperatures, but it’s the margin it’s breaking them by — it’s not even close to what the previous record was,” said Brian McNoldy, a senior research associate at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science. “That’s what’s raising the eyebrows of a lot of people.”  

Average sea surface temperatures today are roughly 1.25 degrees Fahrenheit higher than they were from 1982-2011, according to the University of Maine’s Climate Reanalyzer . It’s a huge anomaly that could have significant effects on weather and ecosystems. 

Human-caused climate change is likely playing a role, researchers said, but is probably not the only factor. Climate models predict a steady rise in sea surface temperatures, but not this quickly, and ocean surface temperatures also fluctuate and can be affected by natural climate variability, including patterns such as El Niño and La Niña.  

So scientists don’t yet know precisely why sea surface temperatures have climbed so high. 

“I pray we’re having a once-in-a-lifetime year of hot sea surface temperatures, but I do fear there may be something else going on that is causing a long-term change in sea surface temperatures we hadn’t predicted,” said John Abraham, a professor at the University of St. Thomas who studies ocean temperatures. “All bets are off now, this is something that is so unusual, it’s challenging our past expectations.” 

If ocean temperatures continue to break records, that could bleach corals, generate more intense and fast-developing hurricanes, drive coastal temperatures up and make extreme precipitation more likely — events scientists already observed in 2023.

Temperatures first soared to record levels in mid-March last year, according to the Climate Reanalyzer, which tracks average measures of sea surface temperature data from across the globe. The data used to measure these trends dates back more than 40 years and comes from networks of monitoring buoys and robotic devices designed to help meteorologists make weather forecasts.

Abraham suspects the main cause of the trend is climate change, with some natural ocean processes that aren’t well understood playing a role, as well.

Average air temperatures are roughly 1.8 F higher today than they were from 1979-2000, but water has a greater capacity to absorb and store heat — the ocean has absorbed about 90% of the heat created by global warming. So, seas were not expected to warm this much already.

“It takes a lot of heat to raise water’s temperature,” Abraham said. 

He and McNoldy both acknowledged, however, that it’s possible that an ocean system has crossed a critical threshold because of global warming. 

Last year, some scientists also pointed to El Niño, a natural pattern that involves warm ocean water in the tropical Pacific Ocean, as a factor driving average sea surface temperatures up.

But now El Niño is dissipating, so they suspect something else is at play. 

“What we see now driving high temperatures is something in addition to El Niño and can’t be explained by the arguments being given six months ago or 12 months ago,” Abraham said. “Sea surface temperatures are higher elsewhere and very far from El Niño locations.”

McNoldy listed other dynamics that may play a small role, including the weakening of trade winds in the North Atlantic, which has reduced the amount of dust blowing from Africa’s Sahara Desert  toward North America. Dust absorbs the sun’s energy over the Atlantic Ocean, so it’s possible that more radiation is being absorbed into the ocean. 

“That could be a factor, but I don’t have a good sense of being able to quantify it,” McNoldy said. 

Some researchers have also suggested that changes to maritime shipping regulations may have reduced sulfur pollution in ship exhaust, ultimately reducing cloud cover and allowing the oceans to absorb more energy. 

“All these little ingredients by themselves don’t explain what we’re seeing, but maybe in a combined sense, they do,” McNoldy said, though he added that he’s skeptical of the theory but can’t rule it out.

Whatever the reason, higher sea surface temperatures can pose dire threats. Warmer water provides more energy for storms to feed on, so “the ones that form often become stronger,” Abraham said.

Warmer waters also increase the risk of rapid intensification — when hurricane winds intensify suddenly as they near the shore. Last year, Hurricane Idalia went from a Category 1 to a Category 4 in 24 hours . 

Some of the largest sea surface temperature anomalies are in the Atlantic and off the west coast of Africa, where the hurricanes that rattle the East Coast of the United States often start. What’s more, the National Weather Service’s Climate Prediction Center says that there is a 62% chance of a La Niña —  which is associated with active and damaging hurricane seasons —  developing in late spring. 

”Not ideal for a calm hurricane season,” McNoldy said, noting that the extra ocean warmth could also lengthen the season. 

High sea surface temperatures can contribute to more intense coastal rainstorms, as well, Abraham said, by helping to build a more moist and hot atmosphere. 

McNoldy said he’s also concerned about corals, which took a beating last year. 

Warm waters caused some of the worst bleaching events ever observed in Florida and the Caribbean Sea , with stressed corals turning white and expelling the photosynthetic algae that lives in their tissue. 

“If the anomalies we’re seeing now are in place during the hot months, the oceans will be warmer than 2023 and we’ll see even worse coral bleaching events,” McNoldy said. 

Among ocean scientists, he added: “We’re kind of all just observing something strange happening. At some point, someone will come up with an answer, but I haven’t seen that answer yet.”

NOAA and partners showcase ocean action at the UN Ocean Decade Conference

• March 19, 2024

April 8th through April 12th

Take a breath – you’re inhaling oxygen generated by the ocean. The ocean might seem like a distant and vast expanse, but its health directly impacts each and every one of us. The ocean provides sustenance for billions of people worldwide, supporting livelihoods, economies, and cultural practices. Protecting ocean ecosystems is essential for maintaining biodiversity and preserving the wonders of the natural world, and sustaining life on earth.

NOAA and partners will highlight efforts in ocean exploration and ecosystem health through panels and events at the first in-person Ocean Decade Conference held in Barcelona, Spain from April 10-12, 2024, with satellite events happening April 8-9. 

Now in the fourth year of implementation of the UN Decade of Ocean Science for Sustainable Development (2021-2030), this conference will bring together the global Ocean Decade community and partners to celebrate and take stock of progress, and set joint priorities for the future. Speakers will discuss Ocean Decade Challenges for issues such as climate change, food security, sustainable ocean economy, pollution, and extreme weather hazards — and the importance of partnerships at a global scale to work towards solutions to safeguard our planet’s most vital resource.

NOAA will host a booth in the exhibit hall and facilitate several panels and events including:

Tuesday, April 9, 9:00-11:00am
