A 3,500-Nautical Mile Range and 30,000 Liters of Fuel: The Heavy Metrics of the RJ102
Scaling Down the Explorer Footprint
The assumption that a vessel needs to approach 80 meters to achieve serious transoceanic autonomy is a persistent myth in the modern yachting landscape. Cantiere delle Marche has directly challenged this belief with the launch of the RJ102, named Mon Coeur. Measuring 31 meters, this steel-hulled explorer marks the most compact iteration of the shipyard’s rugged RJ line. Co-founder and CEO Vasco Buonpensiere points out that the project materialised because the owners requested the yard’s signature engineering backbone squeezed into a significantly more manageable, personalized package.
Solving the Design Puzzle
Condensing the profile of a heavy-duty explorer into a 31-meter frame presented distinct challenges for designer Francesco Paszkowski. The objective was to maintain the commanding presence and go-anywhere confidence typical of much larger displacement vessels while working within stricter structural limits. To do this, the design team retained the bold lines and purposeful profile characteristic of the RJ family, adapting the proportions to fit a 7.25-meter beam and a substantial full-load displacement of 250 tonnes. The resulting silhouette carries the clear family resemblance but stands out as its own distinct hull.
Heavy Machinery and Transoceanic Autonomy
Beneath the contemporary exterior of this explorer lies an array of serious long-range mechanical specifications. Propulsion is supplied by twin Caterpillar C18 Acert engines, each delivering 533kW of power and conforming to strict IMO Tier III emissions guidelines. With a massive fuel capacity of 30,000 litres, the vessel achieves an impressive range exceeding 3,500 nautical miles while maintaining a steady cruising speed of 10 knots. These technical figures ensure that the yacht is fully capable of remote blue-water cruising, far removed from standard shore-side logistical networks.
Interior Geometry Built for Sharing
The internal spaces, styled by Giorgio M. Cassetta, deliberately avoid standard catalogue templates to prioritize the owners’ actual cruising lifestyle. The layout accommodates nine guests across four suites, including a pullman berth in one guest cabin, with a crew of five managing operations. Rather than overcrowding the interior with excess cabins, the spaces are optimized for a limited group. The heart of the vessel features an expansive owner-operated galley alongside organically shaped, bespoke furniture surrounded by warm, textured natural materials that frame a highly functional base camp.
Redefining the Luxury Venture
The successful completion of Mon Coeur underscores a growing shift away from sheer size toward highly intentional, purpose-built luxury. The shipyard’s collaboration with the owners has yielded a vessel that pairs commercial-grade reliability with highly tailored comfort. By delivering a fully capable steel explorer under 35 meters, Cantiere delle Marche demonstrates that meaningful long-distance cruising is entirely achievable without investing in a massive vessel, reshaping expectations for what a pocket explorer can accomplish.
