The Oasis 42M is Benetti doubling down on a layout philosophy that works. The Oasis Deck is not a marketing concept. It's a structural commitment that changes how you use the yacht. The GRP hull keeps weight down and draft shallow. The MAN V12 engines are proven and serviceable. The hybrid option is smart if you plan to spend time at anchor. This is a well-engineered yacht with a clear point of view.
This yacht is for owners who live outside. If you spend your days moving between the pool, the sun pads, and the water, the Oasis 42M will feel like it was designed for you. If you prioritize interior volume or formal dining spaces, you'll find the salon smaller than expected. The owner's suite on the upper deck is a trade-off. You gain privacy. You lose main deck presence. Know which matters more before you commit.
Resale on the Oasis 34M has been strong. The 42M is too new for brokerage data, but the layout differentiation should support residual value. Operating costs will run $1.5 million to $2 million annually with a full crew. The hybrid system adds upfront cost but pays back if you're at anchor frequently. Benetti's service network is solid. Parts availability is good. This is a yacht you can own and operate without surprises.

RWD extended the main deck aft and opened the midship section to create a continuous outdoor space running nearly 70 feet. The pool sits at the centre, flanked by lounging and dining zones, and a retractable cover turns the whole deck into a single flush plane for events.
That is a structural commitment rather than a styling feature, and it drives everything else on board. The salon sits forward, wrapped in glass on three sides, designed by Bonetti/Kozerski to support the outdoor experience rather than compete with it. If your days move between the pool, the sun pads and the water, this is the layout built for it.
The owner's suite occupies the full beam of the upper deck rather than the main deck, with a walk-in closet, a split bathroom and direct access to a private foredeck terrace. It is quiet and genuinely removed from guest activity, which is an unusual choice in this size class.
That choice costs you something. You give up main-deck presence for the owner, and the salon is smaller than you would expect at 139 feet because the layout spends its volume outdoors. Tony's advice is to decide which matters more before you commit, because both are permanent consequences of the same design decision.
If most of your time aboard is spent at anchor, the 42M is close to purpose-built for you, and the optional Siemens E-Mode hybrid system is the box to tick. It runs hotel mode and low-speed cruising on electric power, cutting fuel burn and noise exactly where you notice them.
The hybrid adds upfront cost and the payback depends on your habits. Tony's rule is straightforward: spend significant time at anchor and the maths works, stay constantly underway and it is less compelling. The rest of the yacht already assumes anchoring, with nearly 70 feet of continuous outdoor deck to spend the day on.
The Oasis 42M accommodates up to nine crew in five cabins. In practice you will run a captain, engineer, chef, two deckhands and two or three interior crew, which Tony estimates at $800,000 to $1 million a year in crew cost depending on experience and itinerary.
Add maintenance, insurance, dockage and provisioning and his total lands between $1.5 million and $2 million annually. Those are his figures, not Benetti's. He puts fuel consumption near 250 litres an hour at cruise, so a 300-hour season is a comparatively small part of the bill. Crew, as always at this size, is the number that moves.
The Oasis 42M covers 4,000 nautical miles at 10 knots. Cruise speed is 14.5 knots and maximum is 16, driven by twin MAN V12-1200 diesels producing 1,200 horsepower each. Benetti does not publish a fuel capacity for this model, so treat the roughly 45,000-litre figure quoted elsewhere as approximate rather than official.
Those are cruising numbers rather than performance numbers, and the boat is better for it. Four thousand miles means moving between the Bahamas, the Caribbean and the East Coast without building an itinerary around refuelling. The GRP hull keeps displacement at 295 tonnes, light for 139 feet 5 inches, which helps both fuel efficiency and manoeuvring in tight marinas.
Yes. The forward section of the main deck is a multipurpose lounge in standard configuration, and an optional layout puts a gym there with fold-out terraces. Open the terraces and the space becomes a fitness studio with unobstructed water views on both sides.
It is one of the better uses of forward deck space in this size range, and it fits the wider logic of the boat: flexible zones rather than fixed rooms. The pool can be covered for an event, the beach platform extends into a waterfront terrace, and the forward lounge changes role depending on the week. You are not locked into one use case.
