Hybrid propulsion on the Benetti Symmetry 67M hybrid yacht
The Benetti Symmetry 67M hybrid yacht arrives as the fourth B.Now 67 metre unit and the second equipped with a hybrid propulsion package. For yacht owners who follow Benetti news closely, this balance between proven steel hull architecture and new generation motors is more than a technical footnote; it signals how quietly hybrid systems are moving from experiment to expectation in large superyachts. On this motor yacht, the hybrid configuration is designed to cut fuel burn during coastal passages while reshaping daily life on board for both guests and crew.
Built by Benetti Yachts in Livorno, Symmetry left the yard in early July 2024 for a first Mediterranean season with 12 guests and 17 crew, a real scale test of hybrid cruising speed routines rather than a shipyard brochure run. According to Benetti’s B.Now 67M delivery notes and preliminary spec sheets, the platform pairs twin diesel engines with electric motors and a lithium-ion battery bank sized to support several hours of low-speed navigation and hotel loads without continuous generator use. Benetti cites indicative figures in the 500–800 kWh range for comparable installations and electric motor outputs around 150–200 kW per shaft, although final numbers can vary by project and owner brief, so readers should refer to the official Symmetry technical file for exact values.
The naval architect team behind the B.Now platform has balanced yacht architecture, tankage and machinery spaces so that the hybrid motors and battery systems do not compromise the signature oasis deck or the generous beach club volumes. For an experienced owner, that means the Benetti Symmetry 67M hybrid yacht offers the same exterior lifestyle as a conventional motor yacht, but with quieter nights at anchor and more flexible routing when marinas are crowded. On paper, the Symmetry yacht keeps the familiar metrics; a top speed around 15 knots, an efficient displacement hull and a comfortable long range cruising speed for passages between Côte d’Azur anchorages and Balearic calas. In practice, the hybrid mode allows the captain to run hotel loads and slow manoeuvres with reduced generator use, which directly lowers vibration levels in the guest cabins and main deck lounges.
Benetti’s published guidance for B.Now hybrid equipped yachts indicates fuel savings in the 15 to 25 percent range when operated in optimised modes, though this depends heavily on itinerary, sea state and crew training. For owners comparing yachts for sale in this size bracket, that shift in acoustic comfort is becoming as decisive as an extra metre of length or an additional infinity pool, even if it comes with added complexity in maintenance schedules and the need for more specialised engineering crew. From a technical perspective, the hybrid drivetrain also introduces new operational modes—diesel-electric, battery assist and silent running—that captains can mix to suit harbour approaches, night passages or early morning departures.

Oasis deck living, beach club rituals and life on board
Where the Benetti Symmetry 67M hybrid yacht really diverges from earlier B.Now deliveries is in how its design team has choreographed life on board around the oasis deck and the beach club. The aft oasis deck concept, already familiar from the Benetti Oasis line, is refined here with a large infinity pool, fold out side terraces and a clear visual connection down to the sea level lounge. Hybrid propulsion underpins this exterior design choice, because lower exhaust and machinery noise makes these open air decks genuinely usable from first light swim to late night cocktails.
Step down to the beach club and you find a full wellness circuit with gym, sauna and steam room, all sitting just above the waterline where traditional motor yacht layouts often suffered from hum and rattle. On Symmetry, hybrid running modes allow the crew to schedule spa heavy mornings or tender shuttles with minimal mechanical intrusion, which changes the daily rhythm of life on board for both guests and the owner. One senior crew member quoted in Benetti’s launch material notes that guests can hold yoga sessions in the beach club while the yacht manoeuvres on electric assist, something that would have been unthinkable on older diesel only platforms. For readers tracking eco friendly yacht technology that actually works on the water, this is a textbook case where hybrid systems move beyond marketing into tangible lifestyle gains, a point explored in depth in the analysis of what sustainable yacht technology really delivers at sea.
The oasis deck and beach club are also where the yacht’s exterior symmetry becomes most evident, with clean sightlines from the infinity pool up through the aft decks and into the main saloon. Benetti’s in house yacht architecture team has worked with the hybrid machinery footprint to keep these decks low, wide and open, avoiding the stacked wedding cake profile that still haunts some older superyachts. For an owner used to traditional yachts, the result is a more fluid project life on the water, where guests move naturally between sea, pool and shaded lounges without ever feeling the mechanical heart beating below.
Reymond Langton interiors, charter signals and the wider hybrid trend
Inside, Symmetry marks a clear departure from her B.Now sisters through interiors by Reymond Langton Design, rather than Benetti’s usual in house styling. The Reymond Langton studio, often associated with highly detailed custom superyachts, has used ten bespoke art installations and a calm palette to frame the technical story of the Benetti Symmetry 67M hybrid yacht in a more residential language. This is not a sinot yacht interior or a radical experimental loft; it is a measured, owner focused approach that still leaves enough neutrality for a demanding charter clientele.
The layout keeps 12 guests in six cabins, with the owner’s suite enjoying the quietest real estate thanks to the hybrid drivetrain’s reduced vibration at typical cruising speed. For charterers booking Symmetry through West Nautical at the upper end of the Mediterranean market, that acoustic refinement will be as noticeable as the Langton design detailing or the Symmetry yacht profile at anchor off Porto Cervo. When you compare this to other custom projects such as those analysed in the feature on how a major custom yacht project reshapes design for demanding charter guests, the message is consistent; hybrid is no longer a niche option but a baseline expectation above 50 metres.
From a market perspective, Symmetry enters the yachts sale conversation as both a private family platform and a signal of where Benetti yachts and their peers are heading on propulsion. Hybrid and electric assisted systems are now routinely delivering double digit fuel savings across comparable fleets, and owners are starting to weigh that against the complexity of maintenance and crew training rather than against pure top speed bragging rights. For readers interested in how broader lifestyle shifts, from wellness to plant based menus, are reshaping yacht life board culture, the rise of concepts such as vegan friendly yachts runs in parallel with this propulsion transition, reminding us that in modern yacht design it is not the length overall, but the wake she leaves.
