Nautitech 46 Open Buyer's Guide
The Nautitech 46 Open occupies a compelling niche in the used catamaran market: a performance-oriented, liveaboard-capable cruising cat that emerged from a serious French multihull tradition while carrying the manufacturing resources of the Bavaria group behind it. Marc Lombard's design brief was unambiguous — sailing pleasure first, comfort a close second — and that philosophy shows in a hull that is notably light for its size, a generous sail plan, and a twin-helm arrangement that keeps the sailors engaged rather than buried under a flybridge. For a buyer stepping into this segment of the brokerage market, the 46 Open represents an honest sailing catamaran dressed in upscale clothing: the panoramic windows, dark wood veneer, and seamless indoor-outdoor living are real and substantial, but they sit on a platform that was genuinely designed to move through the water rather than merely float on it. That said, a significant share of these boats entered service as charter vessels, and a careful pre-purchase survey is essential to distinguish lightly used private boats from boats that have carried rotating crews across thousands of Caribbean or Mediterranean miles.
Layouts on the Used Market
The Nautitech 46 Open was offered from the outset in two distinct cabin arrangements, and both appear on the brokerage market, though charter-configured four-cabin examples are more commonly encountered. In the four-cabin layout, the starboard hull arrangement — two en suite double cabins sharing a common shower stall — is mirrored in the port hull, giving eight berths across four en suite doubles. This layout maximises head count and was the natural choice for charter operators working the Caribbean, Greek islands, and Mediterranean bases.
The alternative three-cabin layout surrenders that port-hull mirroring in exchange for a genuinely palatial owner's suite running the full length of the port hull. More than thirty feet long, this suite combines a double berth, a large en suite, a dressing area, and space for a proper office desk — an arrangement that makes the boat unusually liveable for a long-term cruising couple or a family with a clear sense of hierarchy. Private buyers who ordered new frequently specified this configuration. When shopping, establish early which layout is aboard: the four-cabin boat suits charter-friendly shared passages or large families, while the three-cabin suits serious liveaboard cruisers who want to host the occasional couple without surrendering their own space.
A separate flybridge variant — badged as the Nautitech 46 Fly — also surfaces on the market and should be treated as a distinct model. The Fly carries a reduced sail plan and heavier displacement in exchange for the elevated helm station and its commanding view. Buyers who prioritise sailing performance will lean toward the twin-helm Open version; those who want the elevated vantage point and accept the performance trade-off will find the Fly suits them better.
Equipment and Common Upgrades
Given that a substantial share of 46 Opens were built for professional charter fleets, the brokerage market tends to be well-equipped by default. Chartplotters, autopilot, radar, AIS, and life raft are commonly fitted across nearly all examples encountered. EPIRB is widely seen as well, reflecting commercial and bluewater safety standards. Electric winches appear on the majority of boats, reflecting both the charter industry's preference for easy single-handed sail handling and the wisdom of managing a large rig in a liveaboard context. Solar panels, watermakers, inverters, and air conditioning are widely fitted — the combination that makes tropical cruising genuinely self-sufficient — and bimini coverage is universal.
Dinghy davits and cockpit showers are frequently seen, as is a dedicated freezer alongside the standard refrigeration. Starlink antenna installations have become an increasingly familiar sight as owners have retrofitted satellite connectivity to support remote work or simply reliable communications on passage. Hot water systems and full-boat hot water circuits are common on well-equipped examples.
Owner upgrades tend to cluster around performance and energy independence. Lithium battery banks replacing the original AGM setup are a frequent retrofit, particularly on boats that have been refit for extended cruising rather than returned to the brokerage pool directly from charter. A furling mainsail — in place of the standard full-batten slab-reefing main — appears on some examples as a convenience upgrade for short-handed crews. In the sail inventory department, asymmetric spinnakers, code zeros, and gennakers appear as owner additions on boats whose owners pushed for better light-air performance, since the standard self-tacking jib alone leaves the boat underpowered in light conditions. Heating systems, washing machines, and watermakers with larger capacity tanks reflect the upgrades made by owners preparing for cooler-weather sailing in northern European waters or extended passages.
What to Inspect
The 46 Open's construction uses fiberglass with polyurethane foam sandwich — a competent method for a modern production cruiser, but one that rewards careful osmotic survey work, particularly on charter boats that have seen intensive use and may have been pressure-washed repeatedly or left in the water for extended periods without adequate bottom care. Hulls in warm-water charter service are frequently exposed to hard grounding risks in crowded anchorages, and an independent survey should pay close attention to the hulls below the waterline and around the keels.
The twin saildrive arrangement — two 40hp Volvo Penta diesels, each driving through a saildrive unit — is broadly reliable, but saildrive bellows are a known service interval item that must be confirmed as recently replaced or due for replacement. Saildrive boots typically require renewal on a schedule of several years, and neglected bellows are a bilge-flooding risk that is disproportionately expensive to address if left until the rubber has degraded. Confirm the service history on both units and check for any signs of corrosion at the saildrive leg penetrations.
The panoramic windows that define the Open concept are a structural and weatherproofing point worth scrutiny. The large glazed surfaces and the wide cockpit opening create potential leak points at the frame seals, and any evidence of water ingress into the bridgedeck saloon — staining, soft headliner, or swollen joinery — should be investigated before exchange. The standard bimini arrangement and the integration of cockpit and saloon mean that these seals carry real weather loads on passage.
The rig is a fractional sloop with a tall mast — over 75 feet above the waterline — and a large full-batten main. Rigging inspections on charter boats should be thorough, as standing rigging replacement schedules in commercial service are not always as rigorous as they might be on privately owned boats. Check the furling jib system and any code zero or furling gear for wear, and inspect the mast step and chainplates for any signs of stress or water ingress into the bridgedeck structure. Electric winch systems, where fitted, should be tested under load.
Charter interiors inevitably show wear at the highest-traffic points: companionway treads, cockpit upholstery, galley surfaces, and the saloon floor. This is cosmetic in most cases but can obscure deeper issues if the wear has been disguised rather than repaired. Ask for the maintenance log and, if the boat was on a charter program, the fleet management records.
Availability and Buyer's Takeaway
The Nautitech 46 Open has a robust international presence on the used market. Examples are widely available across the Mediterranean — Greece and France are particularly well-represented hunting grounds — as well as in the Caribbean, notably in Martinique and Grenada, where many charter-program boats transition directly into the brokerage pool. The United States market, particularly the East Coast and Florida, carries a meaningful inventory, and the boat has reached as far as French Polynesia and Australia, reflecting its appeal to long-distance bluewater cruisers. The United Kingdom represents a smaller but consistent source of examples, often private boats from owners who used the boat for northern European passages.
For buyers, the key decision at the outset is whether you want a private-use boat or are comfortable with a charter background. Charter examples tend to arrive with comprehensive equipment packages but require a disciplined survey focused on structural wear, engine hours, and the condition of soft goods and interior joinery. Private boats may have fewer sea miles but can also have deferred maintenance that a busy charter fleet would have been forced to address on schedule.
Pre-purchase checklist:
- Confirm cabin layout (three-cabin owner's suite vs four-cabin charter configuration) and verify it matches your intended use
- Survey both hull interiors below the waterline for osmosis and any signs of impact damage
- Inspect both saildrive bellows and confirm replacement history on both engines
- Check all panoramic window seals and saloon-to-cockpit opening frames for water ingress evidence
- Test electric winches under load; inspect all furling systems
- Inspect the rig top to bottom, with attention to standing rigging age and mast step condition
- Verify functioning of watermaker, solar array, and battery bank (confirm chemistry — AGM or lithium — and state of health)
- Review engine service records for both Volvo Penta units; confirm hours
- Assess air conditioning system operation on all zones if fitted
- For charter-background boats, obtain fleet maintenance records and confirm life-raft and EPIRB service dates
