Where the Oasis concept began
The Oasis 40M is the yacht that gave the range its name and its guiding idea. When Benetti unveiled it, the promise was a beach area that folded the yacht open to the sea in a way the market had not quite seen at this scale. The concept resonated strongly and spawned the wider Oasis family that followed. As the founding model, the 40M still reads as the purest expression of the thinking. The idea proved influential enough that rival yards have since offered their own takes on a folding beach area.
Its success also marked a shift in how Benetti pitched its semi-custom range, moving the focus from decks and saloons to the water itself. The 40M sold well and put multiple hulls on the water within a few years of launch. That commercial response justified the smaller 34M and later developments in the line. The boat earned its place as a modern Benetti landmark.
A stern that opens to the sea
RWD drew the exterior, with naval architecture from Benetti's own research team working alongside Pierluigi Ausonio. The profile is low, wide and contemporary, with clean glazing and a confident stance. The defining move is at the stern, where the upper works fold outward to create a waterside platform more than 10 metres across. That platform wraps around an infinity pool set just steps from the sea. The wide beam and long glazing reinforce the sense of a yacht built around outdoor living.
With the wings deployed, the aft of the yacht becomes a broad terrace at the waterline. It is a genuinely different way to use the back of a boat, and it drives the entire exterior concept. The rest of the deck spaces are generous for the length, with strong indoor-outdoor flow. The styling has aged well against later imitators.

The founding Oasis model still owns the idea of a stern that folds open to the sea.
Calm interiors by Bonetti/Kozerski
The interior comes from Bonetti/Kozerski Architecture, whose restrained, material-led approach suits the boat's coastal purpose. The 40M carries up to 10 guests in five staterooms, served by a crew of seven. The main deck flows towards the water in line with the Oasis theme. Natural light and low horizontal sightlines keep the sea in view from most of the living space. The interior volume is generous for just over 40 metres, which the five-stateroom layout puts to good use.
The owner's quarters are handled as a private zone within the volume, away from the social heart at the stern. Material choices lean towards texture and tone rather than gloss and ornament. The result feels contemporary without chasing fashion. It gives the theatrical aft deck a quiet interior to balance it.

The folding platform, engineered
The Oasis 40M measures 40.8 metres with an 8.5-metre beam and a gross tonnage of around 385 GT. Twin MAN diesels give a top speed near 17 knots, with a cruising range suited to Mediterranean and Caribbean itineraries rather than ocean crossings. The boat is a warm-water cruiser at heart. Its performance figures are typical for a displacement yacht of this size and purpose. Stabilisers keep it steady while the platform is open and in use.
The standout piece of engineering is the fold-out beach area, which required Benetti to solve the structure and safety of opening the hull sides at scale. Getting that platform and its integrated pool to work reliably was the core technical challenge of the design. Once proven here, the mechanism became the template for the rest of the Oasis range. It remains the reason owners choose the boat.
Who the Oasis 40M suits
The 40M suits an owner whose ideal day is spent at anchor with the aft platform open and the pool in use. It rewards warm-water cruising and social gatherings over long passages. At just over 40 metres it stays within a manageable crew and cost envelope for its capability. The boat is aimed squarely at life in the bay rather than the open ocean.
In the market the Oasis 40M helped define a category that others have since chased. It offers proven design authorship and a strong resale story given the range's popularity. Several hulls trade on the brokerage market, which gives buyers reference points on condition and price. For an owner who values the water connection above all, it set the benchmark. That track record gives the model a settled place in the Benetti line-up.
Buying Into The Oasis Line
The line is semi-custom rather than one-off: first owner Tim Ciasulli described settling equipment, interior decor and colours with the yard in just two meetings. That process, and the deck concept behind it, caught on fast - the Oasis 40M debuted at the Cannes and Genoa boat shows in 2018, had roughly a dozen units sold within months, and more than 20 hulls have now been delivered since 2020, with delivery slots reported sold through 2026 and 2027.
Buyers cross-shopping the class look at the Sanlorenzo 44Alloy and 40Alloy, the Sunseeker 42M Ocean and Ocean 460, the Mangusta 39 and the Azimut Grande Trideck, all pitched at a similar 40-metre bracket with their own take on a beach-club stern. What none of Benetti's public materials settle is the hard cost of ownership: no source gives a specific annual running or crew-cost figure for this model, so a serious buyer has to get that number from a management company, not from a spec sheet. Benetti's own naval architecture team, led by Pierluigi Ausonio, has kept the underlying hull consistent across more than twenty delivered units even as the interior design credit has moved between studios, from Bonetti/Kozerski Architecture on the early hulls to Leonardo Santi Design on at least one 2026 delivery - a reminder that a semi-custom platform can still change in ways a spec sheet alone will not show.
Engines and systems
| Engines | Twin MAN V12-1400 diesels, 1,400 hp (1,030 kW) each at 2,300 rpm, shaft drive with fixed 5-blade propellers. |
|---|---|
| Stabilisers | CMC Marine electric zero-speed fins, active underway and at anchor; one brokerage sheet names the model CMC SE120. |
| Bow thruster | Electric bow thruster, roughly 65kW - brokerage sheets disagree on the exact make, so the brand is unconfirmed. |
| Watermaker | Reverse-osmosis watermaker, one brokerage sheet names an Idromar MC9S rated about 9,000 litres/day at 25C - single-sourced, not independently confirmed. |
| Tankage | Fuel 45,000 litres and fresh water 8,000 litres, consistent across multiple directory and brokerage sources. |
| Hull and construction | GRP hull and superstructure in vinylester resin composite, teak decks, vertical stem for extended waterline. Benetti's own materials describe a full-displacement round-bilge hull, though several brokerage listings call it semi-displacement - an unresolved discrepancy across sources, not a typo. |
| Gross tonnage | 385 GT per the main directory sources; some brokerage listings cite 370 GT, possibly an internal-volume figure - flagged as a discrepancy. |
| Design team | Naval architecture by Benetti in-house with Pierluigi Ausonio; exterior by RWD; interiors by Bonetti/Kozerski Architecture on early hulls, with at least one later hull (Lady Sarah, 2026) using Leonardo Santi Design instead. |
| Layout | The tender garage sits forward of the engine room on the lower deck, with crew quarters further forward in the bow. No source gives engine-room standing height or access specs, so treat this as layout-level information only. |
What owners and crew report
Praised the fuel efficiency and cabin quietness at cruise
Called it a big wow on seeing 60 litres an hour fuel burn at about 11 knots, and said the main aft deck was incredibly quiet even under way - you and I could have a conversation like we're having now, we wouldn't have to yell, it's heaven.
Tim Ciasulli, owner of the first Benetti Oasis 40M hullSea trial exceeded the declared top speed by a wide margin
Benetti had declared 17 knots top speed; his boat reportedly reached 22 knots in trials, though he acknowledged the tradeoff: I learned you can't have a fast boat and a yacht at the same time.

The Oasis aft deck only really makes sense if you are someone who likes to leave port and anchor up somewhere - in port, it can't and doesn't work.

What is good, and what to watch
Strong points
- The Oasis Deck genuinely reworks the sternSide gunwales fold down at the waterline so the aft-deck beam expands from 8m to 11m, creating roughly 60 square metres of terrace around an infinity-edge Jacuzzi that visually merges with the sea.
- Real-world efficiency and quiet running praised by an actual ownerThe first owner reported the yacht burned just 60 litres an hour at about 11 knots, and called the main aft deck incredibly quiet even under way.
- Performance beat the builder's own declared numbersBenetti had declared a 17-knot top speed, privately hoping for 19; sea trials on the first hull reportedly reached 22 knots.
- Sustained commercial momentumMore than 20 hulls delivered since 2020, with order slots reported sold out years in advance.
What to watch
- The signature deck only works at anchor, not alongsideYachtBuyer's Reviews Director wrote that the Oasis aft deck only really makes sense if you like to leave port and anchor up somewhere - in port, it can't and doesn't work.
- Storage and equipment space is traded for the terraceThe infinity terrace reduces storage and equipment space typically available on superyachts of this size, per Boat International's owner feature, even though the design team maintains it's all there.
- Even the owner frames it as a compromise, not a free lunchThe first owner, on choosing comfort and openness over raw pace, said he learned you can't have a fast boat and a yacht at the same time.
- No transparent, single published priceWith no official Benetti price list, third-party asking prices for delivered hulls range roughly 20 to 25.5 million euros, making it hard for a prospective buyer to benchmark cost from public sources alone.
Practical detail
| New-build price | No official Benetti price list is published. Brokerage and press figures cluster around 22 to 23 million euros for a standard-spec new build. Delivered and pre-owned hulls have listed anywhere from about 20 to 25.5 million euros depending on customisation and build year. |
|---|---|
| Running and crew costs | Not specifically published for this model. No attributable source gave a real cost breakdown, so none is stated here. |
| Ordering process | A semi-custom production model, not a one-off custom build. First owner Tim Ciasulli described negotiating equipment, interior decor and colours in just two meetings. The line debuted in 2018; by November 2018 roughly a dozen units had reportedly sold, and as of 2026 delivery slots have been reported sold for 2026-2027. |
| Comparable models | Sanlorenzo 44Alloy/40Alloy, Sunseeker 42M Ocean/Ocean 460, Mangusta 39 and Azimut Grande Trideck are cited as the closest 40m-class competitors with similar beach-club features. |
