Jeanneau TH33 Preview
Power catamarans make up less than 10 percent of the U.S. powerboat market, but the segment is experiencing double-digit growth as people discover the multihull appeal. These boats offer more living space, better stability, improved fuel efficiency, and a lower likelihood of seasickness. Yes, it can be difficult to find an extra wide berth and a yard that can haul them. Smaller power cats, however—think less than 40 feet—can still tuck into regular slips. And they offer, on average, 20 percent more space than monohulls of the same length. A lovely example of a compact family-friendly multihull cruiser is the Jeanneau TH33.
Interestingly, the TH33 is both new and not new. The Marc Lombard-designed model started its life as a Four Winns. Then, a strategic shift by parent company Beneteau in Q4 of 2025 rebranded this boat and its bigger sister, the TH38, into the Jeanneau family. The move allowed this fun cruiser to enjoy a relaunch and an introduction to a slightly different demographic.
Bow, Cabin and Head
The Jeanneau TH33 is a catamaran, yes, but it is also a bowrider. As such, it features copious seating forward. Passengers have access to a chaise longue to port, additional seating to starboard, and an optional forward ladder. Leveraging the breadth of a multihull, this bowrider has enough space for six people to relax forward. Once you add a table, happy hours will be very happy.
Jeanneau concealed a surprise under the starboard seat. Lift the seat bottom to reveal access to a surprise cabin that buyers can option with a double bed, reading lights, and a bit of stowage space.
The port hull hides another surprise. It features a well-proportioned wet head with an electric toilet, a sink, a shower, and generous headroom. You access the space via a hinged door built into the console ahead of the companion seat.
The boat has a 25-gallon freshwater capacity to facilitate doing the dishes and taking quick showers. A couple could easily spend weekends aboard this model.
Jeanneau TH33 Helm
Moving aft from the open bow, you pass through the hinging wraparound windshield. It’s angled and lower than the hardtop, so plenty of breeze funnels through to the cockpit. Jeanneau placed the helm to starboard and supplied it with twin seats with bolsters, twin 12-inch Garmin multifunction displays (MFDs), engine throttles outboard of the wheel, and a joystick with dynamic-positioning functionality.
On port are two more seats with another dedicated MFD so the mate can help navigate. Wireless charging stations are on both sides, and a Fusion stereo is connected to speakers throughout the boat, including overhead.
Cockpit
A galley console is tucked behind the companion seat. Buyers can outfit it with Corian countertops, a grill, a sink, a 90-quart refrigerator, and drawers. The chef has easy access to all of the important cooking tools.
A two-person aft-facing corner bench is to starboard, backing up to the helm seat. A bigger L-shaped version runs along the transom and the port side. A table turns this area into a dining spot.
Overhead, the hardtop reaches back over the galley, and an extending soft-top sunshade protects the rest of the cockpit.
Stowage space is exceptional. Water toys, coolers, fenders, docklines, and the other necessities of boating all have a dedicated place since there are two hulls into which you can pile loads of gear. Cubbies large and small are spread out below the sole as well as throughout the boat. Some of the spaces are large enough to hide waterskis or fishing poles, though this isn’t really a fishing boat.
Performance and Propulsion Options
The U.S. market loves outboard engines and the builder knows that, so buyers can outfit the Jeanneau TH33 a few different ways. Maximum horsepower for the TH33 is 600, and buyers can get twin twin Mercury or Yamaha outboards. Twin 250s are standard.
According to company testing with standard power, owners can expect a good cruise in the low 20s and a top speed around 33 to 36 knots. By design, the twin-hull platform is stable throughout the speed curve, holds steady in turns, and is fuel efficient with improved planing times and speeds. The two motors are set wide apart, which makes maneuvering in tight spaces easy.
A longitudinal platform between the engines provides easy access to the water. As luck would have it, this platform also hides a very ergonomic ladder with railings, so climbing back aboard after a swim doesn’t require much athletic prowess.
Jeanneau TH33 Entertaining Mode
Jeanneau rates this boat for up to 14 people, which is about 10 more than I’d like to have aboard. But that’s more about me than the boat. If you like to entertain in the harbor or at the dock, the Jeanneau TH33 provides 400 square feet of deck space to accommodate a crowd. I’d weekend the heck out of this model and then zip home at top speed without ruing the trip to the fuel dock.
At the Miami International Boat Show where I toured it, the Jeanneau TH33 had a special price of $500,000 for a well-optioned version. You should expect pricing will vary with location and outfitting, however.
