Sanlorenzo SD118 Yachts For Sale

The tri-deck design includes a sun, upper and main deck, but it is the upper deck that is the clear star, an asymmetrical design that creates a long spread of teak from bow to stern and an upper salon with huge sliding glass sections that merge inside to out. At the stern, the SD118 has one of the best beach clubs around at this length with folding terraces and spectacular pillars. 

Two salons are joined by five ensuite cabins, including a huge full-beam stateroom, with buyers offered a vast array of options on the final layout and finish.

The semi-displacement hull design will hit around 18 knots with twin MTU engines, with cruising speeds of around 12-15 knots and an estimated range of at least 2,500nm.

Buyers in the 35-37m sector have surely never been more blessed with choice and the SD118 sits at the very summit of that fleet. A perfect balance between interior and deck space is headlined by a superb upper deck layout that merges inside to out, adding balconies, massive glass doors and spectacular lounges. It is easy to focus on the SD118’s deck spaces, especially with its two-tier foredeck and outstanding beach club, but the interiors are also class-leading particularly the owner’s stateroom. This SD118 Buyer's Guide will take a look at her inside and out.

The Sanlorenzo SD118 is a 35.75m (117′3″) tri-deck motor yacht in the builder’s semi-displacement SD series. It offers the volume, cruising range and layout flexibility of a much larger yacht while staying under the 40m and 500 GT thresholds. Designed for long-range comfort and onboard privacy, the SD118 suits owners looking for autonomy, livability and low-friction upkeep.

Ease of upkeep and long-term flexibility

Built in GRP with proven commercial-grade systems, the SD118 offers global serviceability, no corrosion risk and straightforward compliance for private or charter use.

• GRP construction avoids corrosion and has shown no systemic issues in early hulls
• Engines, gearboxes and generators from MAN, CAT, ZF and Kohler support global servicing
• Stabiliser seals require routine service but support long-term reliability
• Built to RINA class with optional LY3/REG charter coding and 50/60Hz shorepower flexibility

The SD118 draws in experienced yacht owners and design-conscious clients who want long-range autonomy without the scale or complexity of a full steel superyacht. Most buyers arrive with a clear sense of how they’ll use the yacht. Many are stepping up from smaller Sanlorenzo builds like the SL86 or SD96, seeking more space and better range. Others are coming down from 45m to 50m yachts to reduce running costs and simplify crew operations while keeping full tri-deck living.

The model lends itself to long onboard stays and a quiet, private cruising style. Sanlorenzo designed it for those who see extended sea time as the ultimate luxury, not a rush to the next port. Buyers often use it as a second home that moves with them across the Med, Caribbean or Pacific. Though charter is an option, most SD118s are held for private or mixed use. The fact that production continues as of 2025 confirms strong market traction, and the limited build slots help preserve resale value for existing owners.

Buyers tend to fall into three groups:

• Step-up yacht owners: Buyers moving up from the SL or SD lines who want more range and comfort without stepping into steel. They often stay with their existing crew and work closely with designers to personalise the interior.
• Step-down superyacht owners: Clients scaling down from yachts over 45m to reduce crew size and docking costs. The SD118 keeps tri-deck comfort and long range but is easier to berth and manage.
• First-time superyacht owners: New entrants coming from 100ft composite yachts. They often rely on brokers or shipyard support and use the SD118 as a lifestyle platform rather than a pure investment.

What links these groups is a mindset. They value custom design, comfortable autonomy and the ability to spend meaningful time aboard. These buyers typically invest in layout changes, high-spec interiors and supportive crew infrastructure not to impress others, but to match the way they live.

Where the SD118 Spends Its Time

The SD118’s long range and shallow draft make it well-suited to both cross-ocean trips and tighter cruising grounds. Owners use it in distinct seasonal patterns, often based on infrastructure and climate. Many hulls follow a Med-Caribbean rhythm, some shift between US and Bahamas waters, and others operate year-round in the Gulf or Southeast Asia. 

• Mediterranean: Summer base for most SD118s. Owners favour the Western Med (France, Italy, Spain) for short-range hops between marinas and anchorages. Stern-to mooring is routine, so crew manage passerelle and line work daily. 
• US East Coast & Bahamas: Florida provides easy slips for 36m hulls. With the SD118’s 2m draft, it can explore much of the Bahamas where deeper yachts cannot. Owners here value self-sufficiency - reliable watermakers, air con, and converters ease the load in regions with sparse support. A 60 Hz shore power converter is useful for US marina stops. 
• Caribbean: A common winter charter ground. The SD118 handles open water legs between islands and stays steady in ocean swells thanks to its fin stabilisers. Fuel is cheaper than Europe, and the yacht’s long range means fewer stops. Strong sun and warm seas test the AC and deck gear, so upkeep matters. 
• Middle East: Used by owners who cruise in cooler months or keep yachts in sheds during summer. High heat and dust call for constant filter checks and steady AC loads. Fuel is cheap, but marina space varies. Trips from the Gulf into the Red Sea or Indian Ocean are possible, though some take added security steps for transit routes.
• Asia-Pacific: Long distances and mixed infrastructure make range and reliability key. Owners run between Singapore, Indonesia, and Thailand, using local yards for upkeep when needed. Moisture is a concern - dehumidifiers and soft crew cycles help keep the boat in shape during moored periods. Regional dealers support most systems, though remote repairs may take planning.

The Sanlorenzo SD118 was introduced in 2021 and remains in production as of 2025. It replaced the older SD112 in the builder’s composite range and quickly became a cornerstone of the semi-displacement line. By the time the first hull debuted at Cannes, at least 13 units had already been sold off-plan. That early traction has continued, with strong demand and long lead times today.

There’s a steady progression from early builds to later ones, but no sharp generational cut. All SD118s share the same hull and asymmetrical deck structure. Updates have come through shifts in equipment, interior details and emissions readiness. For buyers choosing between hulls, the main differences lie in engine spec, small comfort tweaks and how owners have customised layout and finish. The core experience holds steady across the timeline.

Concept and Launch (2019-2021)

Sanlorenzo began designing the SD118 in 2019, building on the design language of the SD96. The Zuccon studio led exterior styling, applying the asymmetrical upper deck concept from the SL line to a navetta for the first time. The result launched publicly at Cannes in 2021. Early highlights included a transformer stern, fold-down terraces and a two-level foredeck tied to the master suite. From the start, the builder offered both MAN and CAT engine choices, and the layout left room for owner-led changes. These early units established the model’s appeal as a long-range cruiser with custom interiors and wide flexibility.

Early Hulls (2021-2022)

The first deliveries ran through late 2021 and 2022. They all used the same base structure and came with zero-speed fins and twin gensets. Owners could choose between MAN V12 1400 horsepower engines or CAT C32s. No major problems emerged. One minor note from the first hull was that crew had to adjust line handling on the asymmetrical upper deck due to the single side walkway. Port and starboard wing stations were fitted to help with visibility. Interiors came from top designers, including Liaigre and Urquiola. These early hulls hold their own today and show how well the platform allowed for personalisation.

Mid-Series Refinements (2023-2024)

Sanlorenzo made a few quiet improvements as more yachts launched. By 2023, the MAN engine lineup became the primary choice, possibly due to emissions rules or availability. The builder removed the MTU option from new brochures. Later hulls were built with space to fit SCR units if needed, though the model does not require Tier III compliance in most cruising zones. Displacement was updated in the specs from around 201 tons to about 215 tons, likely reflecting real-world equipment loads. On the comfort side, joinery isolation improved. Hull 5, for example, received added sound dampening near the engine exhaust to better shield the owner’s suite. Clients also began to ask for an upper-deck captain’s cabin behind the bridge, raising the crew count to seven. These changes reflect use-driven tweaks more than a shift in design intent.

Current Build and Status 

The SD118 continues in build with no sign of slowing. Lead times now run to 18 to 24 months. Each yacht still gets a bespoke interior, and there is no standard décor or fixed update cycle. The core structure remains the same. Latest units ship with updated nav and AV packages, and owners may request hybrid-ready system prep, though the SD118 itself has not gone hybrid. More yachts are now built to charter class by default, as owners seek flexibility. The SD132, which launched in 2023, sits above it in size but does not replace it. 

The SD118 pairs a semi-displacement hull with twin diesel shaft drives to support long-range cruising. Her rounded bilges flow into a shallow V aft, while slight propeller tunnels reduce draft to 1.96 m without compromising prop size or shaft angle. The bow is fine and flared, helping her lift through head seas and keep the foredeck dry. Twin stainless rudders and fixed five-blade props complete the setup. This hull shape softens motion at sea and stays steady through changes in trim. 

Engine Options & Specifications

An upgraded MAN V12-1650 is also available, offering slightly faster speeds and higher load capacity but is less commonly chosen to date.

Survey Hot Spots

• Check hull cut-outs around fold-down terraces for signs of cracking or movement.
• Inspect shaft seals and alignment during haul-out service.
• Review coolant and oil samples against engine hours and usage pattern.
• Confirm stabiliser firmware version and service logs.
• Fuel tank senders and gauges may need calibration or inspection for accuracy.

Choosing between new and used comes down to timing and fit. A used SD118 may already have charter coding, shore converters or upgraded nav gear in place. Some buyers prefer the certainty of a known yacht with documented use. Others want to choose every option and work through the design process. Because the SD118 has only been in build since 2021, even early hulls are still fresh, with parts support and yard knowledge carried across every unit. That continuity helps buyers hold value and run their yacht with confidence.

Buying a New Sanlorenzo SD118

Buying a new Sanlorenzo SD118 is a bespoke experience that blends series production with true customisation. While the yacht is part of the semi-displacement SD range, every build is shaped by the owner's choices. Those looking to customise a new SD118 work closely with Sanlorenzo’s design team and, if they wish, a named interior designer. Lead times for a new order run between 18 and 24 months, though short-lead delivery slots do appear when a contract changes hands. From layout planning to material selection, buyers are involved from start to finish.

Production & Build Process

The Sanlorenzo SD118 is built as part of a defined production schedule, but every yacht is made to order. There are no standard inventory units. Buyers commit to a hull slot and work through a five-phase design and planning process with the yard. Key decisions cover the general arrangement, interior styling and major equipment packages. The build includes scheduled milestones such as hull shell formation, hull and deck joint, engine installation and full interior fit-out. Buyers are invited for in-person inspections, often visiting the yard multiple times. Sanlorenzo encourages this, knowing that owners who engage closely achieve the best result.

Layouts & Interior Choices

Layout flexibility is a defining trait of the SD118. Buyers can configure the guest cabin setup, change crew arrangements and introduce custom rooms such as gyms or office spaces. One of the most common layout changes is the addition of a captain’s cabin on the bridge deck, which raises total crew accommodation to seven. The interior scheme is fully open. Sanlorenzo offers in-house design or collaboration with designers like Liaigre or Patricia Urquiola. Unlike some builders, there is no preset style catalogue. Each SD118 reflects its owner’s taste, right down to door handles and lighting.

Key Options & Upgrades

Sanlorenzo SD118 build options are broad, especially when confirmed early in the process. Buyers can shape how the yacht behaves at sea and how it functions under crew. The following upgrades are commonly selected during planning:

• Choose between MAN 1400 horsepower or CAT 1622 horsepower engines depending on cruising needs.
• Electronics upgrades include Gold and Diamond navigation suites with larger screens and optional night vision systems.
• Crew layout can be expanded with a bridge-deck captain’s cabin to improve service and privacy.
• Deck gear such as telescopic cranes, custom awnings or larger passerelles are offered as upgrades.
• Jacuzzi installation is possible on the sun deck with early structural planning.

Other key SD118 options include watermaker redundancy, frequency converters for global shore power and painted hull finishes. Tropical air conditioning is standard, as are zero-speed stabilisers. Hybrid-ready systems can be prepared if requested, though the model is not currently offered with full hybrid propulsion.

Delivery & After-Sales

Every new SD118 is handed over with full commissioning, typically at Sanlorenzo’s facility in La Spezia. The delivery includes crew training, sea trials and all system documentation. Buyers receive wiring diagrams, manuals, certificates and a builder’s certificate as standard. A new Sanlorenzo yacht warranty usually covers the hull structure for two years and equipment for one year, though machinery components follow the original supplier’s terms. Buyers can extend some warranties, and key coverages may transfer to a second owner during the active period. Sanlorenzo’s after-sales support network and regional dealers guide owners through the shakedown period and assist with service scheduling worldwide.

Buying a Used Sanlorenzo SD118

A used Sanlorenzo SD118 yacht for sale gives buyers the chance to avoid the build wait and take delivery more quickly. Most yachts on the market are still within their first few years, often with low hours and documented upkeep. Because each yacht was built to order, it’s important to check not just condition, but also how well the original layout and equipment match your own use. Some units are more charter-ready, others were kept purely for private cruising. Buyers should look closely at maintenance logs, equipment fit and any early refit works that might add or detract from long-term value.

What to Look For

• Maintenance history: match engine and generator hours with yard service intervals.
• Refit record: confirm any major works such as paint, teak, or stabiliser upgrades through dated invoices.
• Survey evidence: review hull and system reports, and ask for oil or coolant analysis if available.
• Equipment fit: stabilisers, thrusters, or upgraded navigation suites add comfort and resale weight.

Used SD118s hold their ground well. Most listings show low to moderate machinery hours - for example, a 2022 hull might show 500 to 800 hours on the main engines and 1,000 to 1,500 hours on the gensets. This suggests moderate use, often a mix of private and charter. Some yachts may have tropical air conditioning or shore power converters fitted; these extras add value, so check if they were installed. Hulls built with painted finishes rather than gelcoat may show earlier signs of wear or require touch-up by year five. One example, M/Y Let It Be, was offered in 2024 as a turnkey brokerage yacht with known specification and warranty balance, a sign of seller confidence.

Survey & Sea Trial Priorities

• Inspect the fold-down terraces and transom cut-outs for signs of cracking or movement around the openings.
• Run a full grounding check across keel area and stabiliser fin mounts, especially for yachts with shallow draft operation.
• Check the sea water cooling circuits and AC system strainers if the boat has been based in warm fouling waters.
• Confirm stabiliser service records and check for controller software updates on the electric fin system.

Sanlorenzo SD118's running costs reflect those of a small superyacht, covering crew, fuel, dockage, and upkeep. Owners manage these through planned haul-outs, class checks, and steady maintenance. With good care, the yacht holds value and benefits from strong yard support.  

Annual Sanlorenzo SD118 Running Costs

• Crew: The top line. Salaries, insurance, and support costs for a full team often reach €400k per year, based on role and region.
• Fuel: Usage varies. At 11 knots, the yacht burns around 300 L/hour. With genset loads and a typical mix of cruising and anchor use, most owners budget €100k–€200k per year.
• Dockage: Home berths and summer slips add up. In the Med or US East Coast, total dockage and utilities might reach €80k per year.
• Insurance: Full cover for hull and machinery sits around 1% of value, or ~€130k. This rises if the boat charters or enters storm zones.
• Repairs & Spares: Annual lift, bottom paint, and routine service might land at €150k in a standard year. Refit years cost more.

In total, owners often hold a working budget of €900k-€1 million per year, depending on use and crew setup. Those who charter may recoup some of that, but high guest traffic raises wear and service needs.

Maintenance Rhythm

• Year 1-2: Under warranty. Minor fixes, sensor tweaks, soft system updates. First oil changes and system checks.
• Year 3: Light refit window. New AV kit, paint polish, or soft upgrades. Mid-term services on cooling gear and hydraulics.
• Year 5: Big class survey. Pull shafts, inspect rudders, run fire and raft checks. Paint touch-up or full respray often planned now. Some owners swap decks or rework worn trim.
• Year 10: Heavy refit. Top-end engine service if hours require it. Full repaint, nav kit refresh, teak swap likely. HVAC and hydraulics checked or replaced.

Common Refit Patterns

• Interior refresh: new soft trim, floor work, hardware swap.
• Navigation and AV upgrades: larger screens, new controls, better comms.
• Deck and paint work: full repaint or touch-up plus deck repairs by year 5-10.
• Tender and toys: change out inflatables, skis, or seabobs every 7-10 years.
• Systems retrofits: bigger watermakers, waste plant installs, or silent-running kits.

Support & Warranty

Sanlorenzo offers a 2-year warranty on hull and 1-year cover on main systems, with longer terms from engine makers if bought. After that, the yard and its global dealer network support service and spares. 

The SD118 runs best with a tight crew of 5-6, each with clear roles and steady routines. Daily life aboard balances navigation, guest care, deck work, and technical checks. While the yacht has high systems fit and modern tools, it still needs hands-on crew to keep things smooth and safe. The layout supports this with smart flows between decks, a capable bridge, and room to rest between shifts. From Med ports to open sea crossings, the SD118 works well with a solid team in place.

Crew Structure

• Captain: Commands the yacht, plans routes, handles port calls, and keeps contact with the owner.
• Engineer: Looks after engines, generators, electrics, and plumbing. Often backs up on deck for lines and checks.
• Chef: Runs the galley, handles stores, and prepares meals. On trips or charters, plays a big part in guest comfort.
• Chief Stew: Keeps the interior clean and ordered. Manages cabins, meals, drinks, and daily guest needs.
• Deck-Stew: Covers both house and deck tasks. Helps with fenders, lines, laundry, and service.
• First Mate: On some boats, takes charge of deck safety, assists in navigation, and fills in as needed across roles.

The SD118 has space for up to seven crew if needed. This means owners can bring extra hands for charters, long trips, or added care. The crew space has en-suite cabins, a mess, and laundry gear.  

Legal and Operational Notes

The SD118 sits well within crewed-yacht rules. Her tonnage and layout make a full-time captain and engineer a must. The yacht’s walkaround main deck and twin wing stations give strong views for mooring. The upper deck has a one-side-only walk, but cameras and practice cover that. At sea, the yacht holds a true line. In tight marinas, she handles beam winds with power and bow trust, but planning and a steady hand matter.

• Bridge crew split watches on long runs. A three-on, six-off cycle is common when offshore.
• At anchor, one crew often stays by the beach club to watch guests in the water and help with gear.
• The tender launch is a two or three-person job. Calm water is best. Side decks and terraces help as work spots.
• In hot spots like the Gulf or Southeast Asia, strainers and AC loads need daily care. Crew often clean filters each day.
• On Med moorings, stern lines and passerelle gear take a beating. Crew check them often, especially in swell.

Running an SD118 brings legal and paper needs as steady as the yacht itself. Owners will need to insure it properly, choose a flag wisely, and keep key surveys up to date. Whether used for private trips or offered for charter, the yacht must meet rules that cover build, safety, crew, and tax. This section explains what to expect and how best to prepare.

Core Insurance Needs

Owners insure the SD118 under two covers. Hull and Machinery (H&M) covers the yacht itself: hull, engines, tenders, and so on. Protection and Indemnity (P&I) handles third-party risks: injury, spills, and wreck costs. Most SD118s carry both through firms like Lloyd’s syndicates or Pantaenius. Premiums depend on cruising range, storm plan, and whether the yacht will charter. High-risk routes, like the Red Sea or Gulf of Aden, can raise cost or bring extra rules like armed guards or alerts.

• Crew and captain background: Insurers ask for captain’s papers and experience. New owners may be asked to hire a management firm or raise cover.
• Flag and class: Most are flagged Cayman or Marshall Islands and classed under RINA. Both show strong build and upkeep to underwriters.
• Storm plans: Yachts based in Florida or the Caribbean must show how they’ll move out of harm’s way in hurricane season. Insurers may void claims if that isn’t done.
• Private or charter: Chartering calls for commercial cover and stricter crew rules. It can raise the base premium.
• Crew cover: P&I must match rules like the Jones Act if crew are U.S.-based. Most owners buy broad cover to avoid risk here.

Picking a Flag

The SD118 works well under open flags. Most go for Cayman, Marshall Islands, or Malta. These flags handle commercial coding cleanly and let the yacht charter if needed. Some EU owners use offshore flags to stay VAT-free under Temporary Admission rules. The flag also shapes safe manning rules and may affect resale. Whatever the choice, owners need to match the yacht’s use with a flag that fits – and keep all papers clear.

Key Certificates

• Certificate of Registry: Shows name, owner, and flag details. Needed to operate and sell.
• Tonnage and load line: SD118 sits just under 500GT. Flags issue a Tonnage Certificate and often a Load Line Exemption.
• Radio license: Needed for MMSI, call sign, and all bridge gear.
• Class and safety: RINA handles most SD118s. For charter, LY3 or REG Part A coding applies with full safety suite and gear rules.
• Engine records: Include warranty logs, service notes, and hours for main engines and gensets.
• Fire and raft records: Logs showing last test dates for all life safety systems.

Survey & Code

Class calls for an annual survey and a deeper check every five years. Charter use adds more steps under the Large Yacht Code. Most owners build to short-range coding - it suits coast-wise trips and avoids bulkier gear rules. Buyers should ask for all certs on file: class, safety, sewage, and fire. A yacht with clean records and known timelines is easier to insure and sell.

VAT and Customs

EU use brings VAT rules. Non-EU owners can keep the yacht in Temporary Admission (TA) for 18 months tax-free, then reset by moving it out. EU buyers must check for proof of VAT paid or pay VAT on import. Missing VAT documents can block resale or cause a tax bill. In the U.S., foreign-flag yachts can cruise with a license for up to a year. U.S. flag use or charter needs duty paid.

Watch Points for Buyers

• Chain of title: Bills of Sale from first build to now should be clean and in order.
• Class status: Get a fresh Class Status Report. Check for overdue surveys or remarks.
• LY3 compliance: Needed for charter. Ask to see the full coding report and safety list.
• Crew papers: If keeping the team, check their tickets match the flag’s manning needs.
• Emissions notes: SD118 is under 500 GT and built to Tier II. Tier III retrofit may be needed for some zones later.

Staying Compliant

Well-run SD118s stay in class, hold all active documents, and update crew certs as due. Owners or their managers track expiry dates on life rafts, fire bottles, and EPIRB batteries. Charter setups bring extra steps like pollution liability and guest contracts. As long as the yacht holds a clean paper trail and sails with a qualified crew, insurers and flags have no issue. This keeps risk low and use smooth, across borders and seasons.

The SD118 remains active on the brokerage market, despite its relative youth. The market shows a clear pattern: buyers weigh use and condition above hull number.

All of our price data is based on confirmed YachtBuyer Market Watch sales of SD118s and listing records. It is best used alongside the live Sanlorenzo SD118 Prices and comparison tools, such as the current SD118 price gauges so buyers can judge whether a yacht is in step with real trading history.

Historic Market Overview

Prices of a Sanlorenzo SD118 began near €15.9 million in early 2023, then eased down through that year as more hulls entered the fleet. From mid-2024, values lifted briefly, with asking prices pushing toward €16 million again. That uptick was short-lived as by early 2025 the range settled into a tighter band between €15.3 million and €15.6 million. The SD118 Historic Prices graph shows a main curve that has a soft fall through 2023, a lift in 2024, and stability since.

The Sanlorenzo SD118 sits in a sharp corner of the 35 to 38 metre range. It offers a semi-displacement ride, 298 GT of internal volume, and a series build that still allows full interior freedom. Rivals are few that match its mix of handling, space, and layout. These four represent the most direct comparisons in different markets.

Benetti Motopanfilo 37M vs Sanlorenzo SD118

The Benetti Motopanfilo 37M leans on retro styling and long-distance cruising. At 36.8 m (120.7 ft), it measures longer than the SD118 but carries similar volume – just under 300 GT. The hull is also GRP and semi-displacement, though the feel is more traditional. Range stretches to a reported 3,800 nm at 10 knots, and the top speed trails the SD118 at around 16 knots. Inside, the layout echoes Sanlorenzo’s with a main-deck master and four guest cabins, though the skylounge remains symmetrical and there are no folding terraces. Charter clients may see parity, but the SD118 offers more light, asymmetry, and design detail in the upper deck areas.

Custom Line Navetta 37 vs Sanlorenzo SD118

The Custom Line Navetta 37 from Ferretti Group is perhaps the closest Italian peer to the SD118. It carries a similar tonnage (around 300 GT) and length at 37.0 m (121.4 ft), using a conventional three-deck GRP layout with a main-deck master and four cabins below. Styling is safe and broadly appealing. Range matches closely at around 3,000 nm at 10 knots, while the top speed is a touch lower, around 17 knots. The SD118 edges ahead in layout innovation - asymmetry on the upper deck, full beach access on three sides, and the option to push volume deeper into entertaining spaces. Buyers choosing between these two often lean toward taste and onboard experience over numbers.

Ocean Alexander 35R vs Sanlorenzo SD118

The Ocean Alexander 35R brings a more American-Asian feel. Built in GRP, this semi-planing hull runs faster than the SD118, with speeds up to 22 knots and a lower range of about 2,000nm. LOA is 35m (114.8ft), GT sits around 270. Inside, it delivers five staterooms including a main-deck master, and makes strong use of glass and big hull windows. Its wide beam (7.5m / 24.6ft) and open-plan salon feel familiar to U.S. owners. The SD118 trades some of that glass for steadier trim and fuller fit-out detail. Both compete for global buyers, but Sanlorenzo pulls ahead for owners looking beyond spec into brand feel, finishing, and layout nuance.

Westport 117 vs Sanlorenzo SD118

The Westport 117 is the classic American planing yacht in this bracket. Measuring 35.7m (117.1 ft) with a narrower beam and around 230 GT, it sits lighter and faster than the SD118. Top speed reaches 24 knots with MTU engines, but range drops to 2,000 nm at 12 knots. Layouts are geared for U.S. preferences – a clean main-deck salon, often five cabins, and simple systems with an eye toward easy refit. There’s no asymmetry, no beach club terraces, and lower internal volume. Owners who want speed and known resale inside the U.S. may lean Westport. Those who value deck flow, long-haul comfort, and European brand presence will find more to hold in the SD118.

To see how the SD118 stacks up line by line, explore YachtBuyer’s full head-to-head comparisons. They show where space, range, layout, or brand edge the balance - and where the SD118 finds its stride among the best of the 35 to 38 metre class.

With an SD118, a broker’s role is to confirm the facts, cut through options, and make sure the yacht fits how you plan to use it. That means checking more than just price. It means reading the build history, layout fit, and machinery spec in full. Brokers use tools like YachtBuyerPRO to trace each hull’s journey and flag what matters.

The process starts with proof. A good broker checks the hull number, year, engine type such as MAN or CAT, stabiliser spec, and any changes made during ownership. They check class and survey records, build delivery notes, and time on the charter market. Each factor affects condition and value.

Then comes comparison. Using YachtBuyer Market Watch data, brokers set realistic expectations based on hours, service intervals, and refit timelines. They compare interior fit, electronics spec, and charter history. This applies not just to other SD118s but also to Navetta, Westport, or Ocean Alexander where it helps put things in context.

In negotiation, the broker lines up surveys, sea trials, and contracts. They arrange oil sampling, stabiliser checks, and help estimate near-term costs such as paintwork, AC chillers, or genset service. On a yacht with this level of fit-out and engineering, early insight avoids surprises.

Once the deal closes, they help organise flag registration, crew hires, insurance quotes, and yard bookings if needed. Their job is built on facts, planning, and working knowledge. On a yacht like the SD118, that support often means the difference between a clean handover and a slow start.

Every SD118 has its own record. How it was used, who owned it, and what was changed. Knowing that in advance saves time, cuts risk, and avoids wasted cost.

YachtBuyer gives you that story. Listings show confirmed build data, charter use, service history, and refit details. You can compare generations, follow layout tweaks, and see how changes like shore power converters or AV upgrades affect value.
