Navetta 50 (Asante)

The 50 metres that changed what Custom Line builds

The Navetta 50 is the flagship of Custom Line, the Ferretti Group brand that has built more than 300 semi-custom yachts at its Ancona yard since 1996. At 49.9 metres and 499 gross tons, she is the largest yacht Custom Line has put its own name on, and the first built in aluminium instead of the fibreglass the brand had used exclusively for close to three decades. The first hull, later named Asante, launched at Ancona on 8 June 2024 and was commissioned and delivered to her owner that August.

Custom Line announced the project in 2022 as the new head of its long-running Navetta displacement range, and put the first hull into build the same year for a 2024 delivery. Ferretti Group chief executive Alberto Galassi called the launch a design that opens up a new market segment for Custom Line, language that reflects how far outside the brand's established band the boat sits: her nearest sister in the existing Navetta lineup, the Navetta 42, is eight metres shorter and built in composite. A second Navetta 50 hull followed roughly a year after Asante, and Custom Line has said further units are expected at intervals of around eight months once the series is in steady production.

Why aluminium, after 28 years of building in composite

Every Custom Line yacht before the 50 was built in composite, the material the brand was founded on and has used across its Navetta and Saetta ranges since 1996. The Navetta 50 broke that pattern deliberately: her hull and superstructure are aluminium throughout, built to naval-architecture work led by the Ferretti Group's own Product Strategy and Engineering departments rather than an outside yard. Aluminium construction leaves a hull of this length around three times lighter than an equivalent fibreglass layup would be, which is why the yard chose it once the Navetta range grew past the point where composite still made structural sense.

Custom Line and Ferretti Group have put a figure on the payoff: the aluminium hull cuts fuel consumption by an estimated 10 to 15 percent against a steel-built yacht of similar size and volume, and the boat is built SCR-ready, meaning she can be fitted with selective catalytic reduction hardware to cut nitrogen oxide emissions close to zero. None of that is independently audited by a class society or a third-party test, and Custom Line has not published a measured fuel-burn figure at cruise - the 10 to 15 percent claim is the yard's own comparison, repeated consistently across its own materials and independent trade coverage of the launch, but it remains a manufacturer estimate rather than a verified sea-trial number.

Custom Line spent 28 years building in fibreglass before it built this one in aluminium - and put the owner's suite somewhere no 50-metre yacht had put it before.

A forward owner's suite nobody else builds at this length

Most yachts near 50 metres put the owner's cabin on the main deck, generally amidships where the beam is widest. The Navetta 50 moves it instead to the bow of the upper deck, wrapped in full-height glazing with its own private forward terrace that is screened from the rest of the boat. Filippo Salvetti, the exterior designer, has said the move is something no one else had managed at this length, a configuration he associates with yachts 65 to 70 metres long rather than a 50 metre hull. Fitting the suite there required inserting a semi-deck between the main and upper decks to house the helm station, which in turn forced Salvetti to break the continuous horizontal lines that run the length of the rest of the Navetta series.

The interior is the work of ACPV Architects, the practice run by Antonio Citterio and Patricia Viel, who gave each deck what the studio describes as its own individual character rather than repeating a single palette throughout. Aft, the yacht carries a transformable stern with a folding platform that opens into a beach club at the waterline, a detail the design team has said was influenced by the fold-down sterns used on Custom Line's sister brand CRN. The sundeck, set beneath a raised arch that also carries the radar and satcom domes, keeps the deck itself clear of the electronics mast that would otherwise crowd a boat this size, leaving room for a full bar, dining table and lounge seating.

Power, speed and how far she can actually go

Propulsion is a pair of Caterpillar C32 diesels producing approximately 1,450hp (1,081kW) each, driving the Navetta 50 to a top speed of 16 knots and a cruising speed of 15 knots. Those figures are modest next to a planing yacht of similar length, but the Navetta 50 is a displacement hull built for range rather than a fast passage, and her numbers are consistent with the rest of Custom Line's Navetta family. At the more economical end of her operating range, 10 knots, Custom Line and independent trade coverage both put her range at approximately 4,000 nautical miles - enough for an Atlantic crossing without refuelling, and well beyond what her 42-metre composite sister is built for.

Beam is 9.6 metres and draft is 2.2 metres, shallow enough for the yacht to work anchorages a deeper-draft 50-metre yacht could not reach, a point Custom Line has marketed directly alongside the forward-suite layout. She carries nine crew for up to 10 guests across five staterooms, a ratio that keeps running costs and crew accommodation closer to a 42-metre composite yacht than to a full-custom 50-metre steel build. Custom Line has not published fuel or fresh-water tankage, generator specification, stabiliser make, or bow-thruster details for the Navetta 50 - specifications that Custom Line's own full-custom stablemates routinely disclose, and their absence here is worth noting for anyone comparing the boat against a CRN or Ferretti Yachts equivalent.

What Asante proved, and what still isn't public

Asante is not a rendering or a boat show mock-up. She launched at the Ancona yard on 8 June 2024, with her owner and family present for the christening, and was commissioned and handed over that August. She appeared publicly at the Monaco Yacht Show in September 2024 and later at the Cannes Yachting Festival, and a second Navetta 50 hull was delivered roughly a year after the first, confirming Custom Line's stated plan to keep the line in series production rather than build a single flagship and stop. Stefano de Vivo, Ferretti Group's chief commercial officer, said at the project's 2022 announcement that the first hull was being built on speculation, without a confirmed buyer, and that it had already drawn serious interest before completion - a bet that paid off given how quickly Asante found an owner.

What has not followed the boat into the open is a price. Every major listing and brokerage source that covers the Navetta 50 marks her price on request, and Custom Line has never disclosed what Asante or her sister cost to build or buy. For context, brokered Custom Line yachts generally range from the mid single-digit millions in euros for older, smaller pre-owned models up to the low tens of millions for the newest 40-metre-plus composite yachts, but the Navetta 50 is a different scale of project entirely and none of those figures can be extrapolated to her with any confidence. The Navetta 50 went on to win the Living Innovation category at the 2025 Compasso d'Oro-adjacent Miglio Blu Design Awards, external recognition that sits alongside the manufacturer's own claims about the boat rather than replacing independent verification of them.

Design

Who it is for: An owner who wants a genuine 50-metre yacht with shallow-draft flexibility and a semi-custom build process and timeline, rather than the multi-year wait and full-custom price of a steel CRN or Feadship.

Guide price: No public price. Every brokerage and listing source marks the Navetta 50 as price on request; Custom Line has never disclosed a build cost or sale price for Asante or her sister hull.
