Sanlorenzo SX100 Review (2025 Edition) by Aquaholic

On Deck

Light, space, and contact with the water drive the whole design of the SX100 and stepping aboard at the stern you feel it immediately. The beach club wraps around the side, and a drop section at the transom lowers into the water to reveal proper steps, so arrival feels more like walking into the sea than climbing down a ladder.  

The aft deck stays open by design. A crane sits here, rated to lift a tender of about 4.5m (15ft), with room for a personal watercraft alongside. Once the toys are launched, the space clears into a large, flat play area right at the water’s edge.

Where the SX100 really leans into its own idea is the side terrace. It folds up against the hull when under way and drops down at anchor. The split level arrangement turns this whole corner of the yacht into an extended beach club. It sits right on the waterline, with glass all around, so the sea stays in view whether you sit, stand, or lean over the rail. This area also reflects Sanlorenzo’s approach to owner choice. The layout shown is one option, but the furniture plan is not fixed. An owner can shift the balance between bar space and seating, or rework the area entirely.

From this lower deck beach club level, movement stays clear. There is a guest stair and a separate crew route. The guest stair links directly up to the main deck and back down to the beach club, so circulation stays simple and intuitive.

Higher up, the upper aft deck carries a serious grill setup, the sort that signals long afternoons at anchor rather than quick meals. Above that, the mast carries satellite domes, radars, antennas, navigation lights, and searchlights, all grouped neatly out of the way.

At main deck level aft, an exterior cockpit opens out from the saloon. From here, you can walk forward along the side decks toward the bow. The foredeck is expansive. It connects directly to the owner’s cabin via a private side door, so it can serve as a personal terrace. Bimini poles allow proper shade, sunpads sit forward, and the anchor handling gear stays hidden beneath flush covers on both sides. Stand right at the bow and look back, and the scale of the boat becomes clear, with the owner’s cabin stretching across the main deck and the bridge set above.

Inside, the main deck saloon immediately reinforces the exterior message. The windows are huge,  pulling light deep into the space and keep the water in view from almost every angle. 

The galley arrangement depends on layout choice. In the configuration shown, the galley sits on the lower deck. It carries the expected working equipment, including fridge freezer and full cooking facilities. A dumbwaiter runs from here to the main deck and continues up to the upper deck, which makes service workable across all three levels. A sliding door allows the galley to close off from guest areas, and that same door leads straight into the crew zone. It is a practical setup that lets crew move through the boat without crossing guest routes.

Sanlorenzo also offers an alternative general arrangement. In that version, the lower deck gains a fourth guest cabin and the galley moves up to the main deck. The galley then takes over the forward section of the main deck, using the full width and depth of that area. Dining shifts into a dedicated dining room with a large table, seating six, creating what the host describes as a kitchen diner or country kitchen feel. It is a layout choice rather than a compromise, and it comes down to whether an owner values a main deck owner’s cabin or prefers four guest cabins below and a more communal cooking and dining space above.

Up on the upper deck, dining sits here in the standard SX100 layout. That explains why the dumbwaiter travels the full height of the yacht. A bar area and refrigeration support this deck, and the lift only opens when the carriage is present, avoiding any open voids. The finish throughout feels distinctly Italian, with careful detailing and a sense of style that runs through cabins, saloons, and circulation spaces. Final materials, stone choices, and finishes all sit within the owner specification.

Owner's Cabin

In the layout shown, the owner’s cabin occupies the forward section of the main deck. It feels expansive, with wide views out through the side windows and a strong sense of openness. A private door leads directly onto the foredeck, allowing the bow to work as a private terrace when desired.

Inside, a dressing area functions as a walk in wardrobe, with hanging rails on both sides. The en suite sits aft, with the shower set within the bathroom. Storage appears throughout the cabin, as you would expect at this size, and blinds drop down over the large windows when privacy or shade matters.  

If the alternative layout is selected, this entire owner’s cabin area converts into the main deck galley and part of the dining arrangement, trading private space for a more social main deck plan.

Guest Accommodation

Guest accommodation is on the lower deck, accessed from the beach club level. A door separates this area from the rest of the deck when required.

One guest cabin includes two single beds plus a Pullman berth. The berth layout can change at order stage, depending on owner preference. Storage includes shelving and a hanging locker tucked behind the door. This cabin has its own en suite bathroom with a shower.

Opposite is a double guest cabin. Storage runs along the cabin side, and the television integrates into the mirror. A hanging locker sits within the cabin, again located behind the door. The en suite uses pocket doors and includes a rainfall shower.

Forward, the VIP cabin is larger again. A television hides behind the mirror, with a hanging locker behind the door and additional storage to the sides. Extra lockers sit near the bathroom entrance. The VIP en suite is larger than the others, with a separate shower compartment and a door to close the space off fully.

Crew Accommodation

Crew areas link directly to the lower deck galley via a sliding door, keeping service routes efficient. This zone includes a crew mess, additional laundry facilities kept away from guest spaces, and monitoring systems for the yacht.

Crew accommodation consists of three cabins. There is one double cabin, two bunk style cabins with en suite bathrooms, and a separate single cabin for the captain. Total crew capacity is five.

Crew move through their own stair route, separate from guest circulation. From this stair, there is direct access to the side deck on the main deck level. The dumbwaiter also arrives here, forming a small pantry area that supports service on the main deck.

Engine access involves a ladder down into a control area, followed by another descent into the main engineering deck. There is a full engineering level beneath the beach club, and once down there, the shape of the hull becomes clear, with the V visible overhead. This depth allows Sanlorenzo to push interior volume upward and outward for owners and guests.

The engineering deck houses shore power conversion systems that manage voltage and frequency, along with pumps and water systems. Noise was present during the visit due to systems running, which is typical on a boat still in show preparation mode.

The engine room contains four Volvo Penta IPS 1050 units, each rated at 800 horsepower. They sit as four distinct pods. There is also a more direct access hatch from the aft deck, with steps that drop straight down into the machinery space, offering a simpler route than the one used during the tour.

Performance figures quoted place top speed at about 23 knots, with a cruise around 20 knots. At 10 knots, range extends to roughly 1,300 nautical miles. The space also houses generators and a camera system for monitoring. The machinery area stays compact by intent, prioritising owner, guest, and crew volume instead. Once inside, the space feels workable, and the more awkward access route is not the only option.

A yacht around 30m(100ft) sits firmly in crewed superyacht territory. A common rule of thumb still holds up in practice. Annual running costs usually sit around 10-15% of the yacht’s purchase price. For a yacht valued at roughly €8-15 million, that typically equates to €800,000-2 million per year. Actual spend varies with how the yacht is used, where it cruises, and how the crew operation is set up. A yacht of this size normally carries five crew. At minimum that includes a captain, engineer, deck crew, and interior staff. Salaries form the core of the expense, but they are not the whole picture. Crew insurance, travel, training, certification, and rotation all add up. This is a year round cost even when the yacht does not move.

Berthing also needs realistic budgeting. Marinas charge by the metre, and a 30 metre berth in places like Monaco, Antibes, or Fort Lauderdale is never cheap. Seasonal rates and short term stays add further pressure. Over a full year, dockage alone can reach well into six figures depending on location.

After delivery, Sanlorenzo supports owners through a global service network. This includes warranty handling, technical support, spare parts, and coordination with local service providers. In practical terms, that means the yard stays involved rather than disappearing once the handover photo is taken.

New yachts take their biggest hit on their value early on. Owners who refit sensibly and maintain well tend to protect value better, and major refits every five to ten years are normal and should be planned carefully (and financially). Sanlorenzo also runs a dedicated refit and lifecycle programme under the Sanlorenzo Timeless banner. This allows owners to update systems, improve efficiency, or rework interiors later in the yacht’s life with factory backing.

The Sanlorenzo SX100 commits fully to its core idea of light and space. It keeps the owner and guests close to the water, from the wraparound beach club and side terrace to the glass lined saloons and main deck owner’s cabin. Outdoor spaces feel deliberate and usable, not added on, and circulation between decks stays clear. If the brief calls for light, water contact, and a yacht that feels open from the moment you step aboard, the SX100 makes its case quickly and sticks to it all the way through.
