Our Thoughts

The 2025 MJM 4 is a 46-foot modern express cruiser that combines thoughtful design, premium construction, and genuine performance capability in a platform purpose-built for both extended cruising and entertaining. Based in Naples, Florida, this example showcases MJM's signature approach to lightweight, efficient hull design paired with the kind of equipment and finish quality that appeals to serious boating enthusiasts who value seaworthiness alongside style.

Power and Performance

Twin Volvo Penta 440HP D6 DPI engines drive the MJM 4 to a maximum speed of 43.45 knots, delivering the kind of responsive acceleration and smooth cruising characteristics that Volvo Penta's diesel platform is known for. The integrated joystick piloting system—a hallmark of modern Volvo Penta propulsion—makes docking and low-speed maneuvering intuitive and confident, even in tight quarters. With a 475-gallon fuel capacity and 3-foot draft, the vessel balances range and efficiency with the ability to access shallower anchorages and coastal cruising grounds. Engine hours at listing stand at just 67, reflecting the vessel's new status.

Layout and Living Space

The MJM 4's open-air cockpit design flows naturally into the helm and salon, creating a cohesive entertaining environment without the compartmentalization that can feel confining on smaller vessels. Forward and midship cabin accommodations provide comfortable sleeping arrangements for extended trips, while the galley, head compartment, and storage are thoughtfully integrated throughout. The 12-foot beam maximizes interior volume without sacrificing handling characteristics, and the convertible social seating arrangement in the cockpit adapts easily between cruising and dockside entertaining.

Electronics and Navigation

Garmin systems anchor the navigation suite, including the GMR Fantom 18x radar—a solid-state system that delivers reliable target detection and weather imaging without the moving antenna of traditional radars. The Garmin ecosystem integrates seamlessly with modern autopilot, chartplotting, and fishfinding capabilities, providing the situational awareness and operational efficiency that serious cruisers expect. The addition of a SIONYX Nightwave thermal camera extends visibility and safety during low-light operations, a practical upgrade for extended or night cruising.

Notable Equipment and Options

This MJM 4 arrives with substantial factory upgrades and options. The Metallic Peppermint Blue hullside paint is a striking aesthetic choice that sets the vessel apart visually. Forward and aft cockpit covers, combined with an aft bimini shade, provide weather protection and UV mitigation for extended time on the water. The removable bow table and drop-leaf cockpit table offer flexible configurations for entertaining or casual dining. Below deck, 43-inch and dual 32-inch smart LED televisions in the galley and cabins provide entertainment options, while the 120V electric grill expands galley functionality for entertaining. Underwater lights add ambiance to evening anchorages, and 12V fans in the forward and midship cabins support comfort during warm-weather cruising.

Construction and Ride Quality

MJM's lightweight epoxy-infused hull construction is engineered to reduce weight, improve efficiency, and deliver a notably softer ride in moderate sea states compared to conventional solid laminate designs. This approach translates to better fuel economy, higher speeds for a given engine package, and reduced fatigue during extended offshore passages—meaningful advantages for owners who plan to cruise beyond protected waters.

2025 MJM 4: A 46-Foot Luxury Cruising Yacht with Twin Volvo Engines and Premium Entertainment Features
Overview
The 2025 MJM 4 represents a modern approach to mid-range luxury cruising, combining refined accommodations, open-air entertaining spaces, and capable twin-engine propulsion into a 46-foot platform designed for owners seeking both performance and comfort. Built by MJM Yachts, known for lightweight composite construction and efficient hull design, this particular example is finished in distinctive Metallic Peppermint Blue and powered by twin Volvo Penta 440HP D6 DPI diesel engines, delivering a maximum speed of 43.45 knots. With a 12-foot beam, 3-foot draft, 475-gallon fuel capacity, and 110-gallon water capacity, the MJM 4 balances seaworthiness with the shallow-draft accessibility that appeals to cruisers exploring coastal and protected waters. Located in Naples , Florida, this 2025 model carries only 67 engine hours, indicating minimal operational use. The vessel is equipped with an extensive list of factory options and upgrades, including advanced Garmin navigation and radar systems, joystick piloting, multiple entertainment displays, specialty lighting, and thermal imaging capability. The configuration reflects an owner's focus on modern conveniences and entertainment-oriented cruising rather than fishing or commercial operations.
Design Philosophy and Construction
MJM Yachts has built a reputation on lightweight epoxy-infused composite construction, a design approach that reduces weight while maintaining structural integrity. This methodology directly impacts the MJM 4's efficiency and ride quality. The lighter displacement allows the twin 440HP Volvo Penta engines to achieve impressive speed performance while maintaining reasonable fuel consumption for a vessel of this size and capability. The hull design emphasizes soft-riding characteristics in moderate sea states, a priority for owners who cruise extended distances and prioritize comfort over extreme performance. The 46-foot length, 12-foot beam, and 3-foot draft create a platform well-suited to Intracoastal Waterway cruising, Gulf of Mexico day trips, and coastal exploration where shallow-draft accessibility matters. The modest draft enables approach to shallow anchorages and protected waters that larger, deeper-hulled yachts cannot reach, expanding cruising territory for owners based in Florida and the Southeast.
Helm and Navigation Systems
The MJM 4 is equipped with integrated Garmin navigation systems as a standard feature, providing modern chartplotting, autopilot, and vessel monitoring. This particular example includes the Garmin GMR Fantom 18x Radar, an advanced solid-state system offering superior target detection and weather overlay capabilities without the rotating antenna of traditional radars. Solid-state radar operates quietly and requires less power than conventional systems, making it ideal for cruising yachts where reliability and low maintenance are priorities. Joystick piloting, powered by Volvo Penta's integrated system, transforms docking and close-quarters maneuvering. The joystick coordinates both engines and steering input, allowing single-handed operation and intuitive control that reduces the learning curve for owners transitioning to larger vessels. This system is particularly valuable for solo cruising or when entertaining guests on the helm. The helm layout connects visually to the salon and cockpit areas, supporting the vessel's open-air design philosophy. This layout allows the operator to maintain social engagement while maintaining helm awareness, a practical consideration for cruising yachts where entertaining and navigation occur simultaneously.
Power, Propulsion, and Performance
Twin Volvo Penta 440HP D6 DPI diesel engines deliver the propulsion for this MJM 4. The D6 DPI (Direct Fuel Injection) engine is a six-cylinder diesel known for smooth operation, responsive power delivery, and modern emissions compliance. At 440 horsepower per engine, the combined 880 horsepower output generates a maximum speed of 43.45 knots, positioning the MJM 4 as a capable cruising platform capable of reaching distant anchorages efficiently. Diesel propulsion offers inherent advantages for extended cruising: lower fuel cost per hour compared to gasoline, superior torque characteristics, and the ability to operate at reduced throttle settings for fuel-efficient cruising speeds. The 475-gallon fuel capacity supports extended range, with actual distance capability dependent on cruising speed and sea conditions. At moderate cruising speeds, owners can expect range sufficient for multi-day coastal cruises without refueling. The joystick piloting system integrates with both engines, providing coordinated thrust vectoring that simplifies docking and maneuvering in confined spaces. Volvo Penta's integration ensures that engine management, steering, and thruster coordination (if equipped) operate as a unified system rather than independent components.
Deck Layout and Entertaining Spaces
The MJM 4's design prioritizes open-air entertaining and social connectivity. The cockpit area features convertible social seating that adapts to different entertaining scenarios—casual conversation, dining, or lounging. This flexibility reflects the vessel's cruising yacht mission, where the outdoor spaces serve as primary entertaining areas during warm-weather cruising. This particular example includes multiple shade and weather protection options: a forward cockpit cover, aft cockpit cover, and aft bimini shade. These factory-installed systems extend usable entertaining time by providing protection from sun and light rain, critical for Florida-based cruising where afternoon thunderstorms and intense solar radiation are seasonal realities. The removable bow table and additional drop-leaf cockpit table expand dining and social configurations. These modular elements reflect modern yacht design, where flexibility and multipurpose spaces appeal to owners who entertain frequently and value adaptable layouts over fixed, single-purpose areas. An integrated swim platform provides convenient water access, a standard feature on modern cruising yachts that supports swimming, watersports, and casual interaction with the water. The platform's integration into the transom design maintains aesthetic coherence while serving practical functions.
Cabin Accommodations and Interior Refinement
Below deck, the MJM 4 provides spacious forward and midship cabins, accommodating multiple guests for extended cruising or overnight entertaining. The forward cabin typically offers a full-size berth with en-suite head facilities, while the midship cabin provides additional sleeping capacity. The specific berth configuration and head count reflect MJM's focus on comfortable overnight accommodations for cruising couples and small groups. Premium upholstery, beautifully appointed cabinetry, and modern amenities throughout the interior establish the MJM 4 as a luxury cruising platform rather than a utilitarian fishing or work boat. Abundant storage throughout addresses the practical reality that cruising boats require secure stowage for provisions, safety equipment, personal items, and spare parts. MJM's design emphasizes accessible, organized storage rather than cramped, inefficient lockers. The enclosed head compartment provides privacy and comfort, a fundamental amenity for overnight cruising. Modern fixtures and ventilation systems ensure functionality and air quality below deck.
Entertainment and Modern Conveniences
This MJM 4 example includes extensive entertainment upgrades reflecting owner preferences for modern media and connectivity. A 43-inch pop-up smart television in the galley provides entertainment and information access in the primary social space. Smart TVs in the forward cabin (32 inches) and midship cabin (32 inches) extend entertainment options throughout the vessel, supporting guest comfort during extended cruising or inclement weather. A high-end audio system provides music and entertainment throughout the vessel, integrated with the cabin TVs and galley systems. The system supports modern streaming services and connectivity, allowing owners to maintain familiar entertainment patterns while cruising. A 120V electric grill enables galley-independent cooking options, supporting entertaining on the aft deck without heating the interior. This practical amenity reflects the MJM 4's entertaining-focused design, where dockside entertaining and casual meals play significant roles in the cruising experience.
Specialized Systems and Upgrades
The SIONYX Nightwave thermal camera represents a specialized upgrade that provides thermal imaging capability, useful for night navigation, identifying other vessels and obstacles in low-light conditions, and general situational awareness. Thermal imaging complements traditional radar and visual navigation, adding a layer of redundancy and capability for extended cruising. Underwater lights enhance the vessel's aesthetic appeal during evening entertaining while supporting practical functions like nighttime swimming or inspection. These lights operate on 12V power and are typically integrated into the swim platform or transom area. 12V fans positioned over the forward and midship cabins provide ventilation and air circulation, supporting comfort in warm climates and reducing reliance on air conditioning during mild weather. Proper ventilation is essential in cruising yachts, where humidity and stagnant air can create discomfort and maintenance issues.
