The Flexplorer 146 is Cantiere delle Marche’s three-deck explorer yacht, built on a full-displacement steel hull with aluminium superstructure for owners who prioritize ocean-crossing range and genuine expedition capability alongside generous living space. She carries 65,100 litres of fuel and delivers a 5,000 nautical mile range at 10 knots, making single-tank Atlantic crossings straightforward. Her 44.50-metre hull accommodates 10 guests in five cabins, with two pullman berths extending capacity to 12, while a crew of nine operates from dedicated forward quarters.
Twin Caterpillar C32 ACERT engines push the displacement hull to 14 knots maximum, and two pairs of zero-speed electrical stabilizer fins keep movement comfortable at anchor and underway. The three-deck layout maximizes usable outdoor space: a full sun deck with optional crane integration for tenders and toys, a main deck saloon that opens onto covered aft seating, and direct water access from a lower swim platform and tender garage. Hydro Tec designed both the naval architecture and exterior lines, preserving the Flexplorer family’s recognizable profile while refining proportions for this third-generation hull.
Each Flexplorer 146 is built to order at CdM’s Ancona yard, giving owners meaningful control over interior layout, cabin configuration, and equipment fit. RINA classification and IMO Tier III-compliant engines meet current environmental and regulatory standards. This is a platform designed for self-sufficient cruising in waters where support infrastructure is hours or days away, not minutes.

The Flexplorer 146 carries 65,100 litres of diesel across a transatlantic range of 5,000 nautical miles at 10 knots. Twin Caterpillar C32 ACERT engines deliver 746 kW each, driving the hull to a maximum of 14 knots when conditions allow. Two pairs of zero-speed electrical stabilizer fins keep the ride comfortable at anchor and underway, while 85 kW electrical bow and stern thrusters provide tight maneuvering in remote harbours. The 15,950-litre freshwater capacity extends time away from marinas, and a UREA tank ensures compliance with IMO Tier III emission standards in regulated zones. Built on a RINA-classified steel hull, the 146 is constructed to handle the weather that coastal yachts avoid, giving owners access to itineraries from the Norwegian fjords to the Southern Ocean.
Hydro Tec shaped the Flexplorer 146’s exterior to balance visual weight across three decks without losing the rugged proportions that mark the range. The bow rises with a pronounced flare to shed spray in head seas, while the superstructure steps back progressively to keep the profile clean and reduce windage. A key design choice is the configurable crane arrangement: owners select between a visible A-frame crane or a concealed system integrated into the sun deck overhang, depending on whether they prioritize working aesthetics or a sleeker silhouette. The steel hull carries a painted aluminium superstructure, creating a two-tone composition that breaks the vessel’s mass when viewed from the waterline. Side passages remain wide enough for safe crew movement in rough conditions, and aft decks open close to the water for dive operations and tender launches.
Five guest cabins accommodate ten passengers, with two additional pullman berths that bring capacity to twelve when needed. The full-beam owner’s suite sits on the main deck with direct access to natural light on both sides. Guest cabins occupy the lower deck, each with private en-suite facilities. Crew quarters forward house up to nine staff across five crew cabins, keeping service spaces separate from guest areas. While CdM builds each Flexplorer 146 to owner specification, the standard layout preserves generous volume in every cabin by keeping corridors efficient and eliminating wasted passageway space. Interior design is left to the owner’s chosen studio, giving each hull a distinct character. The three-deck arrangement frees the upper deck for a sky lounge or additional entertaining space, depending on how the owner plans to use the yacht.
The sun deck defines the social heart of the Flexplorer 146, offering an open-air platform that doubles as a functional operations area when the crane is deployed. Below, the main deck saloon serves as the primary living space, with sightlines forward and aft through large windows that connect the interior to the seascape. The dining area seats all guests in a single sitting, and the galley is positioned for efficient service whether entertaining formally or running a casual expedition itinerary. Aft main deck space extends into a covered outdoor area suited to warm-climate cruising. On the lower deck, a swim platform and tender garage provide direct water access, while storage lockers accommodate the equipment an expedition yacht requires: dive compressors, water toys, fishing gear, and shore-going tenders.
Cantiere delle Marche builds the Flexplorer 146 to order at its facility in Ancona, Italy. Each hull moves through the yard on a timeline that allows genuine customization rather than late-stage option changes. The steel-and-aluminium construction provides a stiff, corrosion-resistant platform with a displacement of 439 tonnes at full load. RINA classification ensures insurance and flag-state recognition across international waters. Twin Reintjes 542L gearboxes transfer power from the Caterpillar engines at a 3.955:1 ratio, optimized for low-rpm cruising efficiency. Generators deliver 2×99 kW to support hotel loads independently of the main engines. The Flexplorer 146 is positioned as a model-range yacht, meaning buyers can review the general arrangement and specification as a starting point before working with the yard to tailor the build.
