2023 Power Buyer's Guide

Forever Green
For this, our third edition of the Power Multihull Buyer’s Guide, we’ve introduced a new category, one that brings together multipowers that are more respectful of the environment. Powered by electric motors and capable of recharging their batteries efficiently, they are able to navigate for a few hours (or even much longer as long if a reasonable speed is maintained) without producing any polluting emissions. Let’s hope that tomorrow, all multipowers will be forever green…

OVERBOAT 100F

Electric flight for anyone

 
 
This modern and futuristic pocket catamaran allows anyone to fly above the water thanks to its four electronically controlled and automatically adjusted foils. These retractable appendages make it easy to leave from a beach or a pontoon, and return to your starting point. The Overboat is capable of a top speed of 15 knots thanks to its 4.5 kW electric motor in the single-seater version. At 12 knots, there’s enough power for 2 hours. The Overboat, which is classified under category D, passes very well through an 18” (0.5 m) chop, which is quite rare for a boat of this size. A “Classic” version, without foils, is also available.

Builder: Neocean 
Length: 10’4” (3.34 m) 
Beam: 4’5” (1.35 m)
Max. draft: 2’7” (0.80 m)

ELECTRICAT BIG SIX

Betting on inflatables

 
 
At a time when paddleboards and many small boats are now adopting inflatable technology for their construction, the choice of the manufacturer Hovercraft to offer inflatable catamarans is not all that radical... The models available today are somewhat smaller than the first 8.30 that we discovered in January 2020 at Boot Düsseldorf. We’re taking a look at the Big Six, which has 130 square feet (12 m²) of usable space on deck and another 65 sq ft (6 m²) up top, and can sleep six.

BAGOÙ 8.0

Open and electric

 
 
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, 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. We’re really keen to see how new and even more efficient battery technologies will provide high performance for longer!

TIMESQUARE 20

Designed for daytrip use

 
 
NEW
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 10 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 for day sailing

 
 
Designers Jean Marc Piaton and Clément Bercault have created a trimaran powered by a 50 kW Torqeedo Deep Blue electric motor. Thanks to its moderate displacement and especially the narrowness of its hulls, this multihull 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.

PINBALL

Hybrid and versatile

 
 
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 diesel engine of 265 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.

VOLTAIRE 33 SKY

100-mile range in full electric mode!

 
 
NEW
Voltaire Electric Yachts is banking on a modern motorboat concept: zero emissions, durability, performance and luxury. The Voltaire 33 SKY is an elegant Open catamaran designed for day-use. She is due to be built in a flax fiber composite with bio-epoxy resin, an attractive alternative to all-polyester. But the main interest of this new 100% electric model is the announced range: 100 miles at 9 knots and a top speed of 17 to 20 knots! To achieve these results, the manufacturer is counting on twin 50 kW Deep Blue motors and two 42 kWh BMW i3 batteries.

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.

ELIGHT 50

10 kWp of solar panels

 
 
NEW
On the strength of four years’ experience in the field of “electrification” of their internal combustion engine powered cats, Nova Luxe Yachts unveiled their first “in house” model just over two years ago, and this has been further upgraded since. Rather elegant with a low deck line at cockpit level, the Elite 50 offers a beautiful living space and a huge flybridge. The flybridge is protected by a hard top, which supports 10 kWp of solar panels - enough to provide enough power for 24 hours at anchor. The builder is also offering as standard a hybrid propulsion system with 55 kW electric motors and 80 HP diesels, though other combinations are possible.

WHISPER 50

A new range of powercats from 40 to 60 feet

 
 
NEW
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 320 square feet (30 m²) of solar panels (6 kWp), a 200-kWh battery pack and two 100-kW Torqeedo electric motors. The Whisper-Yachts 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 375 sq ft (35 m²), generously bordered by sliding windows. The manufacturer offers a three or four-cabin version.

SILENT 60

A catamaran emblematic of eco-boating

 
 
This electricat was launched over a year ago now, but it was only presented to the public for the first time at the recent Cannes Yachting Festival. 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). A version going under the name of the 62 3-Deck transforms the flybridge into a proper upper deck.

OCEAN ECO 60 Coupé

Banking on fuel cells

 
 
NEW
With a sportier design than that of the OCEAN ECO 60 and the ECO EX 60, 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 has already been sold, and the build has just begun. Launch scheduled for late 2022.

SOEL SENSES 62

Available in two versions, Cruise and Power

 
 
NEW
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.

CLASS 6 POWER

Hybrid or full electric

 
 
O Yachts, based in Latvia, have launched a power version of their Class 6. 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.

GR63

Wind, sunshine, and fuel cells

 
 
NEW
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 GR63 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 (4 x 5 kWh), high efficiency wind generators (2 x 10 kW), a large surface area of solar panels (totaling 15 kWp), powerful electric motors and, of course, a large battery bank (between 100 and 200 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 catalog also features a GR52 and a GR75.

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.

COSMOPOLITAN 66

An electric offshore catamaran in aluminum

 
 
NEW
German entrepreneur Christian Braun and Iván Salas Jefferson of Iddes Yachts are launching Cosmopolitan Yachts, a new brand of custom-built aluminum electric catamarans. The first model they’ve announced is a 66-footer designed for unlimited offshore cruising, with construction expected to begin in October 2022. The emphasis has been placed on the sea-keeping qualities of the hulls, 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.

NEW
At this year’s Cannes Yachting Festival, Sunreef Yachts unveiled the first model in its Supreme range 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.

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

 
 
NEW
Sunreef have launched a range with six models from 60 to 130 feet that are fully electric. The 80 Sunreef Power Eco, the first model on order from the Gdansk Shipyard, 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 will also be equipped with a high-tech battery bank: 30% lighter than the batteries used in the yachting industry, with a density of less than 13 lbs (6 kg) / kWh with greater efficiency and performance. This fully customizable luxury catamaran can be equipped with a kite for enhanced performance and range.

SERENITY 84

Reverse bows and clean deck

 
 
NEW
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.

Length: 83’8” (25.50 m)

Alva Yachts is a German builder established at the very beginning of the 2000s. The yard offers a new range of luxury electric catamarans.

WiderCat 92

Extending bulwarks and aft platform

 
 
NEW
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 WiderCat 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)
