Benetti Resizes the Oasis 36M's Tanks Around How Owners Anchor

What did Benetti actually change on the Oasis 36M?

Benetti stretched the Oasis line to a 35.6 metre 36M and rebuilt its bow, deck machinery and tanks around data from the Oasis family already at sea, rather than adding a size for its own sake.

Benetti unveiled the Oasis 36M at the Cannes Yachting Festival on 8 September 2026, the third model in a line that already runs the Oasis 34M and 40M. The exterior is drawn by the British studio RWD, the interior by New York's Bonetti/Kozerski Architecture, the same pairing behind the earlier Oasis boats. The new hull runs 35.6 metres (116'10") overall on a 7.8 metre beam and a 2.1 metre draft, and sleeps 10 guests across 5 staterooms. The 34M it effectively succeeds carries a 275 GT rating on a 7.9 metre beam, so the 36M is a longer, narrower evolution rather than a wholesale redesign.

Sebastiano Vida, Benetti's head of product, framed the boat as a product of fleet experience rather than a fresh brief: "With dozens of vessels currently at sea, we enjoyed a unique vantage point from which to observe and learn how owners and their crews truly live the onboard experience." Benetti names four principles behind the changes: expanded living spaces, hydrodynamic efficiency, acoustic comfort and intelligent engineering. The signature Oasis Deck, the fold-down transom arrangement that gives the line its name, grows to about 82 square metres, with a run of nearly 10 metres from transom to saloon entry and 13 metres of sundeck. Inside, Bonetti/Kozerski reworked the layout for what the yard calls a more open, airy feel, and crew pathways are routed separately from guest areas so staff can move through the boat without crossing the spaces guests use, a service detail more often associated with yachts a size or two up.

Why did Benetti shrink the fuel tank and grow the waste tank?

Fleet data showed Oasis owners spend far more time at anchor than underway, so Benetti cut fuel capacity and enlarged the combined black and grey water tank to about 5,000 litres to match how the boat is actually used.

Benetti says the tank changes came directly from watching how existing Oasis owners use their boats: long stretches at anchor rather than long-range passages. The combined black and grey water capacity rises to roughly 5,000 litres, built to cover the multi-day stays the data showed were typical and to let a boat run largely self-sufficient without a shore or tender pump-out. Fuel capacity was reduced from the levels carried on earlier Oasis models, on the same logic: if the boat is not covering distance, it does not need to carry the fuel to do it. Vida described the process as active listening to owners and captains, in which real-world cruising experience is translated into design decisions rather than assumed from a spec sheet.

The tradeoff is real and Benetti has not hidden it. A smaller fuel tank means less range for an owner who wants to cruise hard between anchorages rather than sit at one, and the yard has not published the exact litres removed or the resulting range at higher speeds, only the 2,500 nautical mile figure at 10 knot cruise. Nor has it published the boat's gross tonnage, which would let a buyer compare the 36M against the 34M's 275 GT on more than length and beam alone.

How much fuel does the new hull actually save?

A newly shaped bulbous bow cuts hydrodynamic resistance by more than 10 percent at the yacht's 10 knot cruising speed, holding consumption under 30 litres an hour per engine on the standard twin 1,200hp MAN diesels.

The standard powertrain is twin 1,200hp MAN diesels, giving a 10 knot cruise and a claimed range of 2,500 nautical miles at that speed, with fuel burn held below 30 litres an hour per engine, under 7.9 gallons. The gain comes from a newly developed bulbous bow that Benetti says cuts hydrodynamic resistance by more than 10 percent at cruising speed, a specific and checkable number rather than a marketing round figure. An SCR, selective catalytic reduction, system is fitted as standard for exhaust treatment, in line with Benetti's stated policy across its current range.

Benetti offers a hybrid option, a Siemens Siship EcoProp system, as an alternative to the standard diesel-only propulsion, but it is an option, not the boat as built; Benetti credits it with cutting emissions, fuel consumption and noise together rather than trading one for another. Away from the engine room, hydraulic garage doors, lifting mechanisms and the Oasis Deck's fold-down wings are replaced with electric actuators across the board, which Benetti says run quieter and need less maintenance than the hydraulic systems on earlier Oasis hulls, and which the yard counts as part of the acoustic comfort brief rather than a separate feature. The D.gree monitoring platform behind that shift combines digital-twin modelling, structural modelling and machine learning to track hull and fluid dynamics in real time, intended to flag a developing fault before it becomes an unplanned haul-out rather than simply logging data for an engineer to read later.

What does an Oasis 36M buyer get that the 34M did not?

Benetti has not attached a price, a delivery date or a gross tonnage figure to the Oasis 36M yet, so a buyer at Cannes was choosing a spec sheet and a design language, not a public number.

That gap is unusual for a flagship model launch at a major show, and it leaves an Oasis 34M owner comparing a known 275 GT, 7.9 metre-beam boat already in the water against a longer, narrower design whose tonnage Benetti has not released. The figures likely fill in as build slots sell and the first hull nears completion, in the run-up to the Monaco Yacht Show later in September and into 2027 deliveries, though Benetti has given no date. The 36M sits between the 34M and the 40M in a line Benetti has built around one visible signature, the fold-down Oasis Deck, so the pitch to a 34M owner is less a new concept than a longer, quieter, better-provisioned version of a boat that already sells.

No independent owner or captain has run an Oasis 36M yet: the boat was unveiled at Cannes on 8 September 2026 and every figure in this story comes from Benetti itself. That is normal for a hull days old and not a reason to distrust the numbers Benetti has given, but it does mean the tank rebalancing and the bow's real-world fuel savings will only be tested once the first owner takes delivery and the class's usual second-hand reporting starts.
