A Long-Range Flagship, Not a Sprinter
Custom Line unveiled the Navetta 42 at the 2018 Cannes Yachting Festival as the biggest Navetta the yard had built, a step up from the 30 and 33 metre models that came before it. The brief was explicit: a semi-displacement hull with a bulbous bow, shaped to cover long distances efficiently rather than to win a straight-line contest with a planing flybridge yacht of the same length. Ferretti Group's own engineering department did the naval architecture, working with Zuccon International Project on the exterior and interior.
More than fifteen hulls have been delivered since that first launch, with brokers' running counts varying between 15 and 18 depending on the date they were compiled - itself a sign of how steadily the model keeps selling rather than a discrepancy worth worrying over. Ferretti Group has continued to market her as the brand's flagship Navetta even as the smaller 30 and 33 metre models have expanded around her, and used listings from 2018 through 2025 hulls now circulate on the brokerage market alongside new ones on order.
Range Built Into the Hull
The semi-displacement hull and bulbous bow are the reason that number is possible on a yacht this size. Pushed hard, the standard Caterpillar C32 Acert engines take her to about 16.5 to 17.2 knots depending on which of the four available engine packages is fitted, and MTU 12V 2000 alternatives are offered at both the lower and higher end of the power range. Cruise speed sits around 12 to 13 knots, which is where the quoted range applies - open the throttles to 16 knots and the range falls sharply, the same trade-off any semi-displacement hull makes.
That range matters more than the top speed for the kind of owner who orders a Navetta 42. She is not built to win a drag race back to the marina; she is built to leave the Mediterranean in June and not need to think about a bunker stop until the Caribbean. Light displacement runs around 220 tonnes and full load close to 260 tonnes, which is a heavy platform for 41.8 metres, and that mass is part of what makes the ride comfortable in a seaway rather than merely fast in flat water.
What a Full Customisation Order Can Do to the Platform
Horizon is not a stock Navetta 42. Her owner and captain spend roughly half the year aboard, and the brief pushed the yard on both engineering and layout. The engine room was rebuilt around redundancy and serviceability: banks of fuel filters, a custom fuel transfer system, and separate clean and dirty oil tanks so the crew is not carrying barrels of used oil off the boat at every service - the captain's own description was that they had not lost a cruising day to a mechanical issue in years. The galley was enlarged beyond the standard specification, carved out of cabin space and fitted with professional-grade Gaggenau and Miele equipment.
The accessibility work is the more unusual choice: an inter-deck lift and widened passageways and cabin doors, features aimed less at resale than at one owner's own comfort aboard a boat they use hard. Glass balustrades on deck, oversized Feadship-scale Muir winches, and an electric stern thruster round out a list of changes that make clear the Navetta 42's semi-custom label is not marketing. A buyer looking at a used hull should expect meaningful differences between examples and should ask specifically what has and has not been changed from the standard specification, since the changes are not always visible in a set of brokerage photos.
Buying New or Used
Ferretti Group's own price list quotes the standard-configuration Navetta 42 at EUR 19,800,000, though the four available engine packages and the semi-custom options move that figure meaningfully in both directions. On the brokerage market, asking prices for delivered hulls have ranged from about EUR 16.5 million for an older, four-year example to over EUR 20.5 million for a 2023-built boat with a heavier options list; one 2025-delivery hull was listed at EUR 20,000,000. None of these figures are independently audited transaction prices - they are asking prices, and the gap between asking and sale price on a semi-custom yacht at this level is rarely published.
What is not published anywhere in the material available is a running-cost figure from the yard itself - fuel burn at cruise, annual maintenance, or crew budget. A buyer has to build that estimate from the tank size and the quoted fuel burn at cruise speed, from broker-supplied running-cost ranges for comparable 40-plus metre semi-displacement yachts, and from a specific hull's own maintenance log. Two independent yacht brokerages give the same headline range for the new-build price, which is the only hard number in this section confirmed by more than one source.
Layout and Volume Over Length
Custom Line built the Navetta 42 with a wide-body configuration rather than the narrower, faster-looking profile common on Ferretti Group's own flybridge range, and that choice shows up most in the main saloon and master suite rather than on deck. The master suite alone runs to roughly 50 square metres with its own balcony, a study and dual bathrooms, sized closer to what a 45 to 48 metre full-custom yacht offers than what most 42 metre semi-production motor yachts carry. Ceiling height throughout the guest areas runs close to two metres, unusual on a semi-displacement platform where hull depth is often sacrificed for range.
The bridge carries an integrated five-screen dashboard with two touchscreens, a specification more associated with full-custom builds than semi-production motor yachts, and both a bow and a main garage handle tender storage without crowding the swim platform. A beach club with side-opening access sits aft, connected to the swim platform rather than stacked above it, which keeps the transom usable at anchor even with a tender in the garage. None of this is unique in isolation - wide-body hulls and beach clubs are common enough on new-build motor yachts above 40 metres - but combined with the Navetta 42's range, it makes the case that this is a long-range yacht built to feel like a full-custom one at anchor, even where the hull underneath is optimised for distance rather than deck space.
Engines and systems
| Propulsion | Standard 2x MTU 12V 2000 M72 diesels (1,469 hp each); optional MTU 12V 2000 M86 (1,725 hp) or Caterpillar C32 Acert in two power ratings (1,470 hp or 1,623 hp) - four packages across the range, which changes top speed materially. |
|---|---|
| Generators | Optional 2x 80kW John Deere generators, assembled by Zenero (Netherlands); not confirmed as standard equipment on every hull. |
| Stabilisers | Optional 2x Naiad fin stabilisers, active at zero speed and underway - a used-boat check item, since it is listed as an option rather than standard. |
| Thrusters | Stern thruster standard; bow thruster fitment is not consistently published across brokerage specification sheets, and should be confirmed hull by hull. |
| Watermaker | Optional Idromar 500 watermaker. |
| Tankage | Fuel 37,000 to 38,000 litres; fresh water 4,000 litres, per Ferretti Group and brokerage specification sheets. |
What owners and crew report
Redundancy pays off over years of heavy use
Horizon's captain, speaking about the rebuilt engine room with its clean and dirty oil tanks and custom fuel transfer system, said the crew had not lost a cruising day to a mechanical issue in years - a direct result of specifying serviceability at the design stage rather than after delivery.
M/Y Horizon's captain, via YachtBuyerThe standard galley is a known limitation owners customise away
Horizon's owner had the galley enlarged beyond the standard Navetta 42 specification, carved out of cabin space and fitted with professional-grade Gaggenau and Miele equipment - a change repeated often enough on semi-custom orders to count as a pattern rather than one owner's preference.
YachtBuyer review of M/Y Horizon
What is good, and what to watch
Strong points
- Real transatlantic range on a semi-displacement hullroughly 3,000 to 3,200 nautical miles at 10 knots, backed by a bulbous bow and hull form built specifically for efficiency rather than top speed
- Proven over seven years and fifteen-plus hullsthis is not a first-of-class boat with unresolved engineering; owners have been customising and running the platform hard since 2018
- A semi-custom order genuinely changes the boathull four's rebuilt engine room, enlarged galley and accessibility features show the yard will restructure real systems, not just swap furniture
What to watch
- Key figures are inconsistently publishedgross tonnage alone is quoted anywhere from 348 to 370 GT depending on the source, and no yard-confirmed running-cost figure exists anywhere in the public record
- Several systems that matter to a used-boat buyer are optional, not standardstabilisers, generators and the watermaker are all listed as options on brokerage specification sheets, so two Navetta 42s of the same year can differ in ways that are not obvious from photographs
- Speed is a genuine trade-off, not a footnote17.2 knots flat out is slow next to a planing flybridge yacht of the same length, and cruising above 13 knots erodes the advertised range quickly
Practical detail
| New price | Approximately EUR 19,800,000 for the standard specification, per Ferretti Group's own price list; engine package and customisation move this figure significantly. |
|---|---|
| Used price range | Roughly EUR 16.5 million to EUR 20.8 million for hulls built 2018 to 2025, based on current brokerage asking prices - not confirmed sale prices. |
| Running costs | Not published by the yard. A buyer has to estimate from tank size, quoted cruise fuel burn and comparable 40-plus metre semi-displacement yachts' broker-supplied ranges. |
| What to check on a used hull | How far the specific boat departs from standard - engine package, stabilisers, generators and watermaker are all listed as options rather than standard fitment, and semi-custom orders like hull four (Horizon) show how far a rebuild can go. |
| What is not published | An audited transaction price for any hull; a yard-quoted annual running cost or crew budget; a single, consistent gross tonnage figure - registries and brokers give figures from 348 to 370 GT for the same model. |
