The X100 Triplex is a 28.9-metre explorer that behaves like a yacht half again its size. Its name comes from the layout: three full living decks stacked on a dual-mode hull, giving interior volumes Extra Yachts compares to a 40-metre. That is the whole idea, comfort and space over speed. Designed as a go-anywhere family yacht, she pairs a raised bow and protective hard top with generous, sheltered living areas built for long stays aboard. Construction is GRP with carbon-fibre reinforcement, keeping weight sensible for a 145-tonne yacht that still cruises efficiently. Power comes from a flexible engine package: a standard pair rated at 1,550 horsepower, with options up to 1,800 horsepower or a quad 1,000-horsepower arrangement for owners who want more pace, giving a top speed between 15.5 and 18 knots. The dual-mode hull lets her run economically in displacement or lift for a faster passage. Accommodation is a genuine strength, with five guest cabins for ten and quarters for five crew across the lower, main and upper decks. Above sits a sun deck for open-air living. Stabilisation combines electric fins with an optional Seakeeper for comfort at anchor and underway. For a family that wants the volume, range and presence of a much larger explorer, without the tonnage, running cost or crew of a 40-metre, the X100 Triplex is a clever and well-judged answer.

The X100 is built for reach and comfort rather than speed, and its engine options say as much. A standard pair of 1,550-horsepower units gives a relaxed cruise and a top end around 15.5 knots; owners wanting more can specify 1,800-horsepower engines or a quad 1,000-horsepower package that lifts top speed toward 18 knots. The key is the dual-mode hull, which runs economically in displacement for long passages yet can pick up pace when conditions and schedule allow. Fuel capacity of 17,500 litres supports genuine range for a yacht of this size, and a 145-tonne displacement keeps her steady and sea-kindly. Electric fin stabilisers, with an optional Seakeeper 40, hold her level at anchor and underway. This is propulsion tuned for a yacht that crosses to an island and stays, not one that races back to the marina.
The X100’s exterior is defined by its vertical development. A raised bow and three stacked decks give her the tall, purposeful stance of an explorer, while the full hard top shelters the upper living areas and frames the profile. The remarkable height is what unlocks the interior volume, and the design uses it honestly: this is a yacht that looks like it carries a 40-metre’s worth of space because it does. Exterior living is generous and layered across the decks, from a swim-friendly stern to sheltered social areas and an open sun deck up top. The styling is clean and contemporary, prioritising function and protection from sun and weather over sporty flourish. It is an exterior built for people who intend to spend real time outside, in comfort, wherever the yacht takes them.
Accommodation is where the Triplex earns its name. Five guest cabins sleep ten, spread across decks rather than crammed onto one, with a full-beam master that benefits from the yacht’s height and width. Five crew in three cabins keep her running smoothly on extended trips. Interiors are arranged for genuine liveaboard comfort, with the volume to include proper storage, generous heads and social spaces that do not feel compromised by the compact overall length. Large windows and the tall superstructure bring in light and long views from every deck. The mood is calm and contemporary, a home at sea rather than a showpiece. For families or groups planning to live aboard for weeks at a time, the sheer usable interior space sets the X100 apart from conventional yachts of similar length.
Three decks give the X100 a rare degree of separation between its living zones. The main deck handles the primary saloon and dining, the upper deck offers a second, more relaxed lounge and helm, and the sun deck opens the yacht to the sky with room for sunbathing and al fresco living. Guests can find a quiet corner or a social hub without treading on one another, and the crew can serve without crossing the owner’s spaces. The stern and beach areas connect the yacht to the water for swimming and toys, while the sheltered mid-deck areas stay comfortable in sun or breeze. This layered approach to living space, normally the preserve of much larger yachts, is the clearest everyday benefit of the triplex layout.
The X100 Triplex is built in GRP with carbon-fibre reinforcement by Extra Yachts at Palumbo Superyachts in Italy, giving owners a boutique explorer backed by a major industrial group. The flexible engine and stabilisation options let each yacht be tuned to its owner’s cruising pattern, from efficient long-range passages to quicker coastal hops. As a current production model, layout and finish can be specified within the platform. Indicative pricing for a new X100 sits around eight million euros depending on engine choice and specification, strong value for a genuine three-deck explorer with this much volume. For a buyer weighing the space of a 40-metre against the cost and crew it demands, the X100 offers a genuinely different route: superyacht living, family-run practicality, and the freedom to go where the season leads.
