31m CdM RJ102 MON COEUR Brings Compact Explorer Format to Cannes

Cantiere delle Marche’s 31-metre RJ102 MON COEUR has joined the new-model conversation around the Cannes Yachting Festival 2026, bringing the Italian yard’s steel explorer philosophy into the most compact RJ built so far. The yacht was launched earlier this year, but her appearance in the current Cannes new-model lineup gives the project a wider public platform alongside a large number of performance yachts, production flagships and new-generation cruising designs.

MON COEUR is deliberately different from many yachts in the 30-metre market. She uses a steel hull, carries 30,000 litres of fuel and is designed for more than 3,500 nautical miles of range at 10 knots, giving her the machinery and endurance associated with significantly larger explorer yachts while keeping guest numbers and overall length relatively restrained.

RJ design language reduced to 31 metres

Exterior design is by Francesco Paszkowski Design, which was tasked with preserving the visual authority of the larger RJ family within a 31-metre hull. The result retains the series’ upright, purposeful profile and strong working-yacht cues without making the yacht look like a compressed version of a larger model.

The dimensions underline how much capability has been packed into the platform. MON COEUR has a 7.25-metre beam and a full-load displacement of about 250 tonnes, figures that give the designers enough volume for long-range systems, substantial tankage and a highly personalised accommodation layout.

Rather than chase maximum guest capacity, the yacht was shaped around the owners’ intended use. CdM describes the project as a base camp for a couple exploring the world, with the design developed around how they planned to live aboard rather than around a standard sales layout.

Four suites for nine guests and a highly personal interior

MON COEUR accommodates nine guests across four suites, including the owner’s accommodation and a guest cabin fitted with a Pullman berth. Crew accommodation is for five, creating a comparatively low guest-to-volume ratio that gives the yacht more space for storage, circulation and the practical requirements of extended cruising.

Interior design is by Giorgio M. Cassetta and reflects that owner-led brief. One of the most unusual elements is an expansive owner-operated galley, a choice that moves away from the strict separation between guest and service spaces common aboard many superyachts and instead supports a more informal, self-directed style of life at sea.

CdM says natural materials, warm textures and bespoke furniture were selected to make the yacht comfortable for long periods aboard. The limited number of guest cabins is therefore intentional, prioritising generous spaces and personal use rather than maximising charter-style capacity.

Steel construction and 3,500nm-plus range

The technical specification is where MON COEUR most clearly identifies as a Cantiere delle Marche explorer. Twin Caterpillar C18 Acert IMO Tier III engines are rated at 533 kW each, while the yacht carries 30,000 litres of fuel and is designed to exceed 3,500 nautical miles at 10 knots.

That endurance gives the 31-metre yacht genuine route flexibility rather than limiting the explorer label to styling. The combination of steel construction, relatively modest installed power and substantial fuel capacity is designed around efficient displacement cruising and the ability to remain away from major marina infrastructure for longer periods.

The yacht’s 250-tonne full-load displacement also reflects a construction philosophy built around robustness rather than minimum weight. In this size category, many competing yachts use composite or aluminium structures and prioritise higher speed; MON COEUR instead follows the heavier-duty approach that has defined CdM’s larger explorer fleet.

Range is only useful if the yacht can support the people aboard for the same period, so the customised interior and storage philosophy are important parts of the explorer brief. The owners’ decision to keep accommodation to four suites creates more room for provisions, equipment and everyday living, helping the yacht function as a genuine long-distance platform rather than a compact yacht with an explorer-style exterior.

The modest engine output relative to displacement is also consistent with that mission. CdM is not attempting to turn the RJ102 into a fast yacht; it is optimised around efficient passage-making, predictable machinery loads and the ability to cover substantial distances at economical speeds, which is a different design priority from the 25- to 35-knot performance yachts sharing the Cannes docks.

That distinction is likely to matter to buyers comparing operating profiles as much as interior styling. A 31-metre yacht that can cross long stretches between fuel stops, carry substantial tankage and maintain a five-person crew offers a different ownership proposition from a similarly sized planing yacht designed primarily for short seasonal hops between established marinas.

Cannes puts a compact explorer beside performance-led rivals

Camper & Nicholsons included the RJ102 among its standout new models at the Cannes Yachting Festival 2026, highlighting the way CdM has brought its RJ line below 32 metres without abandoning steel construction or ocean-going range. That makes MON COEUR an instructive contrast with many of the lighter, faster yachts making premieres in the same size bracket.

The yacht is also part of a broader shift in the explorer market. Owners who want genuine range and robust construction are no longer restricted to yachts well above 40 metres, and builders are increasingly trying to package expedition capability into sizes that are easier to berth, crew and operate.

For CdM, MON COEUR extends an already established explorer formula rather than launching an unrelated compact product. The project therefore strengthens the yard’s ability to offer the same long-range philosophy across a wider spread of owner requirements and yacht sizes. The yard’s reputation has been built around displacement yachts intended for serious cruising, and the RJ102 shows how that approach can be adapted when an owner wants the same philosophy in a smaller, more personal platform.

Her presence in Cannes therefore gives MON COEUR relevance beyond a conventional launch story. She is a useful demonstration of how far the modern 30-metre explorer has developed: steel-hulled, long-range and purpose-built for owners who expect the yacht to function as a travelling home rather than simply a seasonal Mediterranean base.
