Fiart’s new SX4 and SX5 Focus on Something Rare in Yachting: Usability

Fiart has launched a new yacht line called the SX series with a fairly straightforward idea at its core: owners who spend extended time onboard care more about usability, circulation, and comfort than another sculpted fiberglass statement piece.

The Italian builder introduced two models — the 16-meter SX4 and the slightly larger 17-meter SX5 — both developed internally by Fiart’s technical office with exterior and interior design by Massimo Simeone. The pitch centers on long-range cruising, social deck layouts, and practical living spaces. Which sounds obvious until you spend five minutes looking at half the yachts launched lately.

A lot of builders have drifted into this weird architectural arms race. More glass. More angular lines. More giant floating villas that photograph beautifully and feel exhausting after two days aboard. Somewhere along the way, yacht design became heavily optimized for drone footage.

Fiart’s SX line feels like a reaction to that. Quietly, but very intentionally.

The main deck setup is the key thing here. Both yachts use a double-cockpit arrangement that splits the outdoor spaces into separate zones without making the boat feel fragmented. You can move from stern to bow cleanly, without climbing over furniture or threading yourself through tight side passages designed by somebody who clearly never carried a drink underway.

And yacht circulation matters far more than yacht companies like admitting publicly.

People romanticize life at sea until they spend a long weekend trapped onboard with guests, towels, bags, wet swimsuits, and nowhere comfortable to move. Suddenly the “award-winning design language” starts to feel less important than whether you can walk around naturally.

Fiart seems to understand this.

The SX models connect the outdoor areas into one continuous environment rather than a collection of disconnected set pieces. The stern platform sits low over the water for swimming and easy access at anchor because every yacht buyer now wants direct contact with the sea, preferably while posting about it from somewhere near Sardinia.

The cockpit shifts between dining and lounging without requiring a full furniture transformation sequence every time somebody wants lunch. The bow remains dedicated to sunbathing because some traditions in yachting are apparently untouchable.

The larger SX5 pushes the whole concept further. At 17.3 meters, it’s clearly designed for owners planning longer cruises rather than some quick afternoon runs between marinas and beach clubs. The aft cockpit features a large rear-facing sunpad and an U-shaped dining area, though the more important detail is the hardtop covering the central section of the deck.

Shade changes boating entirely. People underestimate this until they spend six straight hours exposed to Mediterranean sun reflecting off white fiberglass like a laser beam.

The covered central living space makes the SX5 usable while underway and during longer passages. Which, again, sounds basic. Yet plenty of boats still behave like they were designed exclusively for perfect weather and anchored lunches.

Inside, the SX5 comes with two- or three-cabin layouts, each paired with two bathrooms. The emphasis here leans toward privacy and comfort rather than cramming extra berths into every available corner. You get the sense somebody at Fiart understood owners might spend days or weeks onboard instead of treating the yacht like a floating restaurant reservation.

Power comes from twin Volvo Penta D8 engines producing 550 horsepower with IPS700 drives, with an optional upgrade to IPS800. Enough for serious cruising without drifting into the increasingly absurd horsepower inflation happening across larger yacht segments.

The SX4 carries the same philosophy into a slightly more compact package. At 16.1 meters, it keeps the protected deck concept and open social layout while feeling easier to handle operationally. Frankly, this may end up being the smarter boat for many buyers.

There’s a point where yacht ownership starts resembling facility management.

Like the SX5, the SX4 offers two- and three-cabin configurations. Families can lean toward guest capacity, while couples planning longer stays can prioritize larger living areas instead. Power comes from twin Volvo Penta D6 engines rated at 440 horsepower with IPS600 drives, with an available upgrade to 480 horsepower and IPS650.

What Fiart seems to recognize — and what a surprising number of luxury brands still miss — is that extended time onboard changes what matters. Dramatic styling loses its appeal very quickly when daily life becomes awkward. Owners start caring about shade, movement, seating positions, privacy, noise levels, and whether the deck layout works without constant adjustment.

The SX line feels designed around those realities instead of around boat-show theatrics.
