Built by MJM Yachts in 2025, the MJM 4 is a 14.02-metre motor yacht that represents a masterclass in modern American yacht design. Blending the timeless elegance of a Downeast profile with cutting-edge composite construction and innovative engineering, this vessel offers a rare combination of refined luxury, effortless usability, and exceptional performance for discerning owners who value quality and craftsmanship.
The MJM 4 is powered by twin Volvo 440 HP D6-DPI diesel engines and features joystick docking for confident handling. Her vacuum-infused epoxy composite hull with closed-cell foam coring delivers a lighter, stronger, and quieter ride than traditionally built competitors. Key specifications include a forward convertible berth, private midship berth, and enclosed head with stall shower. The yacht boasts an integrated glass pilothouse system with electrically adjustable dual helm seating, large opening side windows with electrically actuated forward glass, and an aft enclosure for all-weather versatility. Additional features include dual refrigerator/freezer drawers, an induction cooktop, convertible cockpit sun lounge, side and transom boarding doors, and a large swim platform with retractable ladder. Factory options on this example include forward and aft cockpit covers, bimini, 32-inch LED smart TVs in forward cabin and mid berth, 43-inch pop-up smart TV in galley, 120V electric grill, underwater transom lighting, Sionyx Nightwave thermal camera, and Garmin GMR Fantom 18x radar.
Designed around four distinct social zones—bow lounge, pilothouse, cockpit, and swim platform—the MJM 4 excels as a luxury family day boat that combines the social openness of a centre console with the comfort and craftsmanship of a premium express cruiser. Her flush-deck, walkaround layout provides safe and easy movement throughout the yacht, while the modified deep-V hull and advanced engineering deliver impressive stability underway and at rest. Premium teak joinery, high-end soft-close cabinetry, synthetic teak decking, and thoughtful storage elevate the onboard experience. The yacht is engineered to offshore-rated ISO Category B standards and represents an exceptional platform for entertaining, coastal cruising, weekend getaways, or simply enjoying time on the water with family and friends.
