Jeanneau TH38 signals Groupe Beneteau’s wider multihull push

The Jeanneau TH38 is not being positioned as just another new powerboat. It is the clearest signal yet that Groupe Beneteau wants multihulls to matter across more of its lineup, with Jeanneau now carrying a twin-hull range that once sat under Four Winns and is meant to reach buyers far beyond a single home market. The pitch is simple but strategic: bring power catamaran stability, open-plan living and easier handling into a package that feels approachable rather than oversized.

A broader multihull play inside Groupe Beneteau

Groupe Beneteau has spent decades building name recognition through Lagoon in cruising catamarans and Prestige in powercats, and the group now says its portfolio spans 17 brands and services, including BENETEAU, JEANNEAU, LAGOON and PRESTIGE. That makes the TH38 part of a much larger corporate pattern, not a one-off design exercise. The company has also tied its growth story to a B-Sustainable program that targets a 30% reduction in CO2 intensity by 2030, which adds a modernization narrative around the multibrand portfolio.

The TH38 also fits the group’s recent push upmarket. At the 2024 Miami Boat Show, Groupe Beneteau framed 13 new models as part of innovation and transformation, with Jeanneau, Beneteau, Prestige, Excess, Lagoon, Wellcraft and Four Winns all pulled into the same broader brand story. In that light, the TH38 looks less like a niche experiment and more like a deliberate expansion of where the group wants to compete.

How the TH line changed hands

The TH family did not begin with Jeanneau. Four Winns launched the TH36 at Cannes in 2022, then unveiled the TH33 and TH38 at Cannes in September 2025. The transfer to Jeanneau followed shortly after, with one report placing the handover on January 6, 2026 and saying marketing, communication, development and commercialization of the TH series moved under Jeanneau’s oversight in Vendée.

That switch matters because it changes the way the boats can be sold and recognized. Jeanneau has broader global reach than Four Winns in many markets, and the move gives the TH line a stronger platform in places where dealer coverage and brand familiarity shape buying decisions, especially in Asia. The new badge also tells buyers that this is now part of Jeanneau’s own powerboat identity, not an adjacent experiment tucked inside another brand.

What the TH38 is trying to be

Jeanneau is not selling the TH38 as the biggest boat in the room. It is presenting the model as the larger weekender sibling to the TH33, a twin-hull power catamaran built for owner-operators who want easy handling, open social space and enough cabin volume to stretch a day on the water into an overnight. Jeanneau’s own description of the TH33 stresses “generous living spaces,” “exceptional stability” and a “high level of comfort,” and the TH38 extends that same logic into a slightly larger package.

The design team also helps explain the positioning. Camillo Garroni shaped the exterior, while Marc Lombard Yacht Design handled the naval architecture. That pairing points to a boat that is meant to look clean and contemporary while still carrying the practical multihull underpinnings that matter when the sea state turns less forgiving.

Yacht Style’s Cannes sea-trial coverage makes the intended use case especially clear. The TH38 was tested in jumpy conditions, yet the layout still came across as welcoming, practical and confidence-inspiring when the weather was not perfect. That is exactly the kind of promise that sells power cats to owners stepping up from monohulls: more steadiness underfoot, more usable space and less drama at rest and underway.

The layout and tradeoffs buyers will notice

The TH38 leans hard into the kind of social areas that make a catamaran feel different from a conventional cruiser. The bow lounge is reached through an opening central gate and a folding windscreen, a detail that immediately tells you the boat is built for circulation, lounging and easy movement between zones. The living spaces are modular rather than fixed in one rigid layout, which gives the boat a dayboat feel without stripping away overnight capability.

BoatTEST says Jeanneau is offering two windshield versions, a full-height windscreen for more protection and a low-profile version for a more open-air feel. That kind of choice says a lot about the target customer. The TH38 is not trying to define one perfect use case; it is trying to sit between coastal cruising, entertaining and short-stay ownership, with enough flexibility to suit different climates and operating styles.

The tradeoff is size discipline. Jeanneau lists the TH38 at 38'11" overall length, 13'1" air draft, 1'1" draft, two cabins and CE category B9 / C14. Multihulls World adds a beam of 4.47 meters, displacement of 7.42 tonnes, twin 300/350 hp outboards and fuel tanks of 2 x 465 liters, along with 2 x 95-liter water tanks. Those numbers place the boat firmly in the compact powercat bracket: substantial enough to feel like a serious cruiser, but still small enough to remain an owner-run weekend platform rather than a full-scale yacht program.

Why the numbers matter

Those published figures show exactly where Jeanneau wants the TH38 to sit in the market. At 38'11" long with a 4.47-meter beam, it is wide enough to deliver the stability multihull buyers want, but not so large that it drifts into the more complex territory of full-time luxury liveaboard cats. The twin outboards also reinforce the sportier, more accessible brief, especially for buyers who want a powercat without stepping into heavier inboard systems.

The real point is not length alone. It is the combination of beam, draft, twin-hull volume and open-deck usability that makes the TH38 feel like a bridge model. It can speak to monohull owners moving up into multihulls, and it can also appeal to buyers who already know what twin hulls buy them: room, steadiness and a social layout that works hard from breakfast through sunset.

That is why the TH38 lands as a strategy story as much as a product story. Jeanneau is not simply adding a model; it is helping Groupe Beneteau widen the path into multihulls, with a boat sized and styled to make the leap feel less like a jump and more like the next obvious move.
