2024 Multipower Buyer's Guide

Forever Green
For this, our fourth edition of the Power Multihull Buyer’s Guide, the category that brings together the most environmentally friendly multipowers now features right at the beginning of the Buyer’s Guide, rather than at the end. Powered by electric motors and able to recharge their batteries efficiently, some multipowers presented here are capable of cruising for a few hours, some for much longer, provided the speed remains reasonable, all without producing polluting emissions. What if tomorrow, all multipowers were forever green?

BAGOÙ 8.0

Open and electric

 
 
{{ALTERNATIVE::getLinkEssai(434)}}
This power catamaran is original in more ways than one. First of all, the construction is in epoxy plywood, then, it has an open deck - no cabin - and it offers efficient electric motors. During our test of the prototype version, we easily reached 10 knots and were able to appreciate the hull’s excellent passage through the chop. The different power options will allow you to optimize speed or range. The builder now offers its powercat concept in larger models (Bagoù 10 and 12 meters).

TIMESQUARE 20

Mission: boating pleasure

 
 
Austrian boat builder Frauscher specializes in high-end craft - their catalog includes 5 different models of runabout and 4 boats with central console. The company is also well established in the electric boat market with 4 models... What is new, though, is that Frauscher are moving into catamarans, with the TimeSquare 20! This day boat is designed for navigating on protected waters and lakes. A hedonistic program for 7 people which does not skimp on the high-tech side of things, since this multihull integrates carbon fiber in order to reduce its displacement, making it barely a ton. The electric propulsion systems on offer range from 2 x 3 kW to 2 x 12 kW with a battery bank from 7 to 30 kWh. The deck plan totals 215 square feet (20 m²); it is modular and integrates a refrigerator, a sunshade and an audio system.

ORPHIE 29

Pocket-sized electric trimaran

 
 
{{ALTERNATIVE::getLinkEssai(1092)}}
Designers Jean Marc Piaton and Clément Bercault have created a trimaran powered by an electric motor. Thanks to its moderate displacement and especially the narrowness of its hulls, this multihull equipped with a 50 kW Torqeedo Deep Blue can maintain a cruising speed of 10 to 12 knots with a range of 30 nautical miles. The Orphie 29 has been designed to accommodate 6 to 10 people: the table of 6’7” x 2’8” (200 x 80) cm is in the shade and can accommodate the whole crew while the trampolines will be great for hanging out in the sunshine. Inside, a mini-cabin: this space is dedicated mostly to storage but there’s a small bunk that could be used by a child, and there’s also a toilet. This trimaran is simple, elegant and integrates sustainable and environmentally friendly materials in its plywood epoxy construction. That said, for the sake of keeping it light and rigid, the linking arms are made of carbon. A kite wing is also offered by the builder for use in favorable winds, and the Orphie 29 is available in all stages of completion.

PINBALL

Hybrid and versatile

 
 
{{ALTERNATIVE::getLinkEssai(1030)}}
The designers of this platform, developed in the region of the Arcachon basin in southwestern France, chose to use a catamaran configuration so as to offer a deck area 45% larger than that of a monohull. However, the beam is in line with that of a “modern” monohull – 9’8” (2.95 m) in width with a hull length of 27’4” (8.33 m). The aim is of course to use the same size marina slip. The manufacturer has developed an original hybrid drivetrain: one central gasoline engine of 350 HP and two electric motors of 8 kW each, with ducted propellers. At 4 knots, the range in electric mode is two hours. In the internal combustion mode, it is possible to set the electric motors going, but this time using alternator power. The deck plan, which includes a tilting platform, has been optimized for ease of use, comfort and storage. The sundeck folds up to form a mini-cabin for two, VW Combi style.

HERLEY BOATS 3400

Aluminum hulls, hybrid drivetrain

 
 
New Zealand-based Herley Boats, who specialize in the construction of aluminum motorboats, has launched its first powercat with either internal combustion or a hybrid powertrain. The latter option sounds very attractive with its two 100 kW electric motors, 60 kWh of lithium-ion batteries and a 120-kW generator: at 6 knots, you get a nice range of 1,300 miles or 700 miles at 8 knots. The maximum speed is 20 knots. (12 without the help of the generator). The forward windows, with reversed slope are perfect for maintaining good visibility and to limit the greenhouse effect. It would be great to be able to take full advantage of the foredeck with an additional pulpit. Inside, a fully equipped galley and a large main saloon open up onto a large cockpit. Each hull offers a double cabin and a bathroom. A third cabin – a single - is among the options.

CAT 12.0

The electric powercat designed by professional users

 
 
Since 2015. Sun Concept has built more than 30 electric catamarans aimed at either professional or private use.
Based in southern Portugal, the builder launched the Cat 12.0, a very fine-hulled catamaran in 2019. Versions of this model are available to suit various uses – Open for transport of passengers and a large nacelle for cruising. Following the example of her baby sister, the Cat 7.0, the 12.0 is propelled by two electric motors, which are powered by solar panels on the bimini. For safety, a generator allows for minimum functions should the batteries not be sufficiently charged. An all-carbon version is also offered.

E-40 POWERCAT

Fine hulls for limiting drag

 
 
Based in New Zealand since 2016, Earthling has become a specialist in electric drivetrains and offers a hybrid powercat based on the very racy Stealth 36 - a catamaran designed by Australian Alan Carwardine and built in Phuket, Thailand. This sailing-style design is no longer in vogue in the world of powercats, but thanks to the slenderness of the hulls, it generates very little drag at low and medium speeds. That said, the boat’s beam is considerable, and the original coachroof limits the output of the solar panels to 2 kWp. The two powerful 50 kW motors are deliberately oversized - at 10 knots, they consume just 7.5 kW each. This remarkable efficiency is due in part to the large 600 mm (just shy of 24”) propellers, which turn at a relatively slow speed of 400 to 600 rpm. With 22 kWh of battery power in each hull, the E-40 PowerCat has a maximum range of 40 miles in all-electric mode. The maximum range is 18 miles at 10 knots. Two generators, each rated at 8.5 kW, make it possible to maintain this speed without losing battery charge. The manufacturer uses a high-performance, automated interface to free the captain up from the hassle of energy management.

Builder: Earthling
Length: 39’4” (12 m)

ELIGHT 40

Open nacelle for commercial use or closed nacelle for private owners

 
 
Novaluxe, specialists in hybrid and electric powered catamarans and re-engineering, are offering a 40-foot powercat for professional use. Capable of carrying around 40 passengers, the Elight 40 features a large surface area of solar panels capable of producing 6 kWp. The 48V propulsion system is capable of 10 hours of operation – a speed of 5 knots can be achieved using solar energy alone. For safety, a generator can be installed. And while the nacelle is completely open in the dayboat version, it can be enclosed on the Owner version.
In both cases, the hulls are equipped with a full galley and sleeping accommodation.

ELIGHT 44

A new, even more seductive design!

 
 
Nova Luxe’s Elight 44 has been extensively redesigned for a second time compared to the original model. What was previously the 43 now features a more fluid design with larger windows, but its main ambition remains to be high-performance (14 knots all-electric top speed, 4 hours of operation at 6 knots per day) and to be even more comfortable. The manufacturer emphasizes the long range of 1,000 miles at 7 knots (using all energy sources), partly achieved thanks to a drastic “slimming diet”: the new Elight 44 will weigh in at just 9½ tons, compared with eleven previously. The Station Keeping system, which eliminates the need for anchoring in most situations, and the Joystick Docking system - very practical when coming alongside - will also be appreciated. The builder also offers two much bigger models, the Elight 60 and Elight 70.

WHISPER 50

The first model in a new range of forevergreen powercats

 
 
Symphony Marine is getting into the electric catamaran market with models from 40 to 60 feet. Guy Marchal, the founder of the Whisper-Yachts brand, asked Berret-Racoupeau Yacht Design to draw this environmentally friendly catamaran with 430 square feet (40 m²) of solar panels (6 kWp), a 240-kWh battery bank and a pair of either 50 or 100-kW Torqeedo electric motors. The Whisper 50 should be able to provide “clean” propulsion at 5/6 knots. It can of course sail faster - up to 18 knots - but at that speed, recharging the batteries is necessary through the generator and/or the shore power. The deck layout does not seem to inhibit the surface area of the solar panels - many areas remain well clear. Inside, the nacelle offers a decent amount of area, generously bordered by sliding windows. The manufacturer offers a three or four-cabin version.

SOLAR EXPLORER 52

A new brand in the electric world!

 
 
Solar Explorer is a catamaran brand created by the New Zealand team at Herley Boats to focus on the energy transition in recreational boating. The first model presented is a 52-foot powercat, which is currently in build. Construction involves a composite sandwich made using the infusion process. The first drawings reveal fairly high hulls with inverted bows, and a flat coachroof roof that extends into a bimini, providing maximum surface area for solar panels. The inverted forward face, extended by a cap, blends perfectly with the interior helm station offset to starboard. Inside, you’ll find very comfortable accommodation - a large galley with central island, a huge open saloon, and an owner’s cabin that makes full use of the available width.

SILENT 60

A catamaran emblematic of eco-boating

 
 
{{ALTERNATIVE::getLinkEssai(1019)}}
This electricat was launched over two years ago now, and has seen great commercial success, proof that the concept of electric multihulls is no longer limited to a handful of custom examples – we’re now talking series production. The Silent 60 has managed to validate its specifications, i.e. sailing without burning any fuel, thereby not emitting any pollutants, at up to 4/5 knots. The Silent 60, like all the other models from the brand, is of course powered by twin electric motors. The manufacturer offers three formulas - 2 x 50 kW, 2 x 200 kW, and 2 x 340 kW. Extended forward at the front of the coachroof by a cap, and aft by a large bimini, the superstructures are designed to support a maximum surface area of solar panels (450 sq ft/42 m², compared with 325/30 on the previous Silent 55).

OCEAN ECO 60 Coupé

A racier design without a flybridge

 
 
With a sportier design than that of the Ocean Eco 60 Open and the Explorer, the Coupé version differs by having no flybridge. It has only one deck level, but it offers a total surface area of 2,475 square feet (230 m²), while retaining the forward supports of the nacelle that are characteristic to the brand. This reduction in superstructure makes it possible to limit the air draft to just 21’4” (6.50 m) - a dimension more compatible with inland waterways. The manufacturer announces a record range of 2,800 miles with the help of two generators. A full-electric version is also available. The interior promises only the most refined comfort. The first example of this ocean-going electric catamaran is scheduled for imminent launch.

SIXTY SOLAR POWER

Hybrid propulsion and XXL comfort

 
 
Following two years in development, Xquisite Yachts, in collaboration with Dixon Yacht Design, has set up the tooling for the new Sixty Solar Power and begun construction of the first example in Portugal - where Xquisite is setting up its new production facilities in partnership with Corthinx and Walby Portugal. The new model features a design typical of the builder, with coachroof supports in the form of an arch. The Sixty Power uses a hybrid diesel-electric propulsion system. Energy autonomy is based on an immense area of solar panels on the bimini and the T-Top. The builder is putting the accent on on-board comfort.

SOEL SENSES 62

Customizable as you like

 
 
With a length of almost 62 feet (19 meters), the Senses 62 promises impeccable comfort for her crew, especially since Soel Yachts highlights the customization possibilities of their new model: whether it be the layout of the flybridge (it can be closed, for example) or the cabins, all options are possible. The modern design is associated with particularly accomplished technology. The Soel Senses 62 has 17.6 kWp of solar energy, which translates into a daily energy production of 40 to 50 kWh (in good weather). Regarding the propulsion system, the 62 is available in two versions, Cruise and Power. The former has two 100-kW electric motors, a 212-kWh lithium battery pack and a 100-kW generator. This will ensure a cruising speed of 8 knots and a top speed of 12 knots. The 62 Power has a 2 x 200 kW drivetrain and a battery bank that’s also doubled up. On board, priority is given to large openings to the outside. The layout inside is designed to accommodate up to nine guests and three crew. The builder is also getting ready for an even more ambitious model, the Senses 82.

SILENT 62 3-DECK

The brand’s first triple-decker...

 
 
Developed using the Silent 60 as a base, the 62 3-Deck is the brand’s first model with three deck levels. This new model gains 34½” (87 cm) of hull space, but also a 538-square foot (50 m²) flybridge that remains fixed. This generous surface area provides space for a bar, galley, dining table and large bench-seating for 10 to 12 people. The flybridge is of course covered by a vast T-Top, which not only provides protection but also, and above all, means you’ve got optimal surface area for installing solar panels. But the manufacturer goes a step further than the classic open fly version - which is the one we’ll be discovering at Cannes - as this third deck can also be converted into a closed saloon or Owner’s suite.
The drivetrain chosen for this model is identical to that of the Silent 60: despite its displacement now approaching
40 tons, the 62 3-Deck is capable of covering 100 nautical miles in 100% electric mode - at reduced cruising speed, of course. A kite can also be deployed for longer passages at favorable speeds.

CLASS 6 POWER

Hybrid or full electric

 
 
O Yachts, based in Latvia, offer a power version of their Class 6 sailboat. After two years of sea trials, the builder has validated the original “Smart Hybrid” powertrain (the builder’s GTS version). In other words, an electric engine in one hull, a diesel engine in the other. The idea is to take advantage of all the benefits of electric propulsion - no pollution, no noise pollution, the possibility of sailing in protected areas - and of the longer offshore range guaranteed by the diesel propulsion. The fineness of the hulls, combined with a displacement of 11.5t (25,350 lbs), ready to sail, thanks to the composite/carbon construction, allows for minimal consumption: one liter (just over ¼ US gallon) per nautical mile at 9 knots and half that at 7 knots! A “Full Electric” GTE version is also available. All sorts of customization are possible: traditional diesel motors, solar panels, a rig with a short mast, kite wings, etc.

SERENITY 64

Retractable bimini

 
 
So, what’s the winning recipe for the Serenity 64? American marketing and Turkish production. The designers chose to offer a hybrid engine combining two electric and two internal combustion engines: a reassuring and environmentally friendly choice. While the layout is fairly traditional, much attention has been paid to its quality. But what amazed us was the ingenious rigid bimini entirely covered with solar panels, which lowers to the point of almost covering the huge flybridge to reduce air draft and/or windage.

GR63

Wind, sunshine, and fuel cells

 
 
Behind GR are the initials of Gilles Reigner, the former owner of Catathai - who wanted to validate a second brand that is both green and high-end. With a doctorate in physics, this Frenchman living in Thailand is well placed to run a 100% electric powercat project whose energy production is ensured by wind generators and solar panels. The GR60 guarantees a cruising speed of 7 knots and a top speed of 18 knots thanks to a pretty wide range of technical solutions - fuel cells (up to 30 kWh), high efficiency wind generators (2 x 10 kW), a large surface area of solar panels (14 kWp), powerful electric motors and, of course, a large battery bank (240 kWh). The design of this powercat calls for a careful lightweight sandwich construction associated with very fine hulls and optimized aerodynamics. The interior layout and the deck plan are customizable according to the wishes of the owner. The first GR63, due to be launched in less than a year’s time, will feature a 130-square foot (12m²) hydroponic space in the forepeak for vegetable growing! A GR80 is also in the catalog - it won’t go unnoticed with its drone and submarine, both of which are two-seaters...

COSMOPOLITAN 70

An electric offshore catamaran in aluminum

 
 
German entrepreneur Christian Braun and Iván Salas Jefferson of Iddes Yachts have launched Cosmopolitan Yachts, a new brand of custom-built aluminum electric catamarans. The first model, announced last year, was a 66-footer that’s now been extended to 70 – a powercat designed for unlimited offshore cruising. The emphasis has been placed on the sea-keeping qualities of the hulls (note the tunnel between the hulls in a double gull-wing shape), the electric technology, and respect for the environment. Aluminum was the obvious choice thanks to its capacity to be recycled, its lightness and its solidity. Foils have been designed in order to improve comfort. Engineering has been focused on reducing energy consumption and vibration while guaranteeing maximum range and reliability. High-performance electric motors guarantee top speeds of 20 knots. These will be powered by a top of the range battery bank, recharged by solar panels integrated into the design. The builder also offers a Cosmopolitan 85 (available in a “Narrow” version, in the region of 6½ feet/ 2 meters less in the beam) as well as a Cosmopolitan 115.

SUNREEF SUPREME 70 ECO

Maximum comfort with minimum emissions

 
 
Image removed.
Image removed.
In 2022, Sunreef Yachts decided to make its Supreme range available in an ECO version, i.e. electric. The design of the Supreme with the forward face of the superstructure inverted has been maintained, but green technology is used to reduce carbon emissions by the maximum amount possible. Logically, there are solar panels integrated into the sides of the hulls, and everywhere else possible, that are capable of producing up to 30kWp. The solar energy obtained is used both for the equipment on board and for propulsion, ensured by two powerful motors of 180 kW each.
Fully customizable, the Sunreef Supreme 70 Eco offers an infinite choice of layout solutions, including the option of an owner’s suite with sea view on the main deck.

SERENITY 74

6 to 8 knots at cruising speed

 
 
Currently in build, this model is the big sistership to the Serenity 64. Like her, she will be powered by solar energy thanks to 1,185 square feet (110 m²) of panels and two electric motors of 25 kW. The cruising speed in electric mode will be 6 to 8 knots. The underside of the nacelle is relatively high, but notably features an embryonic third hull: this gull wing structure guarantees excellent stiffness to the structure and a smoother passage through bigger seas.

80 SUNREEF POWER ECO

Unlimited range

 
 
Sunreef launched an initial range with four models from 60 to 130 feet (18 to 40 m) that were fully electric, and which has now been completed by two Supremes (70 and 80) and four Ultimas (44, 55, 77 and 88), not forgetting the 40M Explorer. A total of no less than 11 models! The 80 Sunreef Power Eco, the first among these models ordered from the Gdańsk shipyard, was presented as a world preview at the recent Cannes Yachting Festival. This multiyacht promises silent, non-polluting cruising and infinite range. Sunreef’s plan is to reconcile yachting and ecology: by operating a vast multiyacht platform, the builder has succeeded in installing 2150 sq ft (200 m²) of light and ultramodern solar panels - producing up to 36 kWp of electricity. The 80 Sunreef Power Eco is also equipped with a high-tech battery bank: 30% lighter than the batteries used in the yachting industry, with a density of less than 11.5 lbs (5.2 kg) / kWh with greater efficiency and performance. With a 990-kWh battery bank, range in all electric mode is some 300 nautical miles. This fully customizable luxury catamaran can be equipped with a kite for enhanced performance and range.

SILENT 80

Opening roof or three decks

 
 
Following the launch of their 55 and 60, which demonstrated the feasibility of 100% electric power, Silent Yachts is now offering an even more ambitious 80-footer. This new model is seeing excellent commercial success with several examples having been ordered! With her E-power or E-Power+ drivetrain (various options available) and 26 kWp of solar panels, you can sail for hours at a cruising speed of 6-8 knots, and even all night at 5 knots without having to start the generator, not even to cook or run the air conditioning. Built with 4 to 6 luxury cabins - plus crew quarters and galley, the 80 is available with a retractable sunroof or in a three-deck version (the Silent 80.3), with a 970 sq ft (90 m²) sky lounge, open or closed, above the saloon. A tender in the port hull and jet skis on the other side complete the equipment.

SERENITY 84

Reverse bows and clean deck

 
 
Thanks to its long length, the latest model announced by Serenity Yachts features a clear foredeck, resulting in a particularly successful silhouette. The three-level superstructures are of course covered with solar panels - perfectly integrated in terms of design. As for the hulls, they feature reverse bows that contrast with the more traditional designs seen with the brand’s other models. On the sides, the upper recess in the hulls that house the openings for the hull windows is very convincing.

OCEAN ECO 90

All electric or hybrid

 
 
The Ocean Eco 90 is the flagship of the range developed by Alva Yachts. This ambitious powercat is characterized by a modern design. But it is notably her very high bows, and the bulwark connecting them directly to the superstructure, that catch your eye. The foredeck clearly benefits from exceptional protection. As for the flybridge, this accommodates an outdoor saloon, a bar and a jacuzzi. Inside, of course, there is room for ultimate luxury and comfort. In terms of propulsion, this unit will be available all-electric or with a hybrid powertrain.

WIDER 92

Extending bulwarks and aft platform

 
 
The forthcoming 92-foot catamaran announced by Wider Yachts continues with one of the brand’s specialties, namely the mastery of mobile platforms. In this instance, the classic aft platform will be complemented by outwardly pivoting bulwarks, creating a huge uninterrupted horseshoe-shaped sundeck with direct access to some of the cabins. The Wider 92, like all the boats developed by the manufacturer since 2010, also aims to sail emissions-free thanks to the use of solar energy. The first model will have a hybrid diesel-electric drivetrain, but a hydrogen fuel cell may be employed on a future model. The expected top speed is 15 knots, with a range reaching 3,000 miles at eight knots.

Builder: Wider Yachts
Length: 92’ (28.04 m)
Beam: 39’ (11.89 m)
