2025 MJM 4 2025 MJM 4

This 2025 MJM 4 (referred to as MJM 47X in 2026 and newer models) is a masterclass in modern American yacht design—blending the timeless elegance of a Downeast profile with cutting-edge composite construction, exhilarating performance, and unmatched day-boating versatility. Built in the USA and engineered for discerning owners who value quality, comfort, and ease of use, the MJM 4 stands apart as one of the most refined luxury day yachts on the market today.

Designed around four distinct social zones, the MJM 4 creates an effortless flow from bow lounge to pilothouse to cockpit and swim platform, making her an exceptional platform for entertaining family and friends. Her innovative flush-deck, walkaround layout provides safe and easy movement throughout the yacht, while the indoor/outdoor pilothouse delivers true all-weather versatility rarely found in competing day boats. Large opening side windows, electrically actuated forward glass, and an aft enclosure seamlessly connect the helm deck to the outdoors for an open-air experience when desired—or climate-controlled comfort when conditions change.

This exceptionally equipped 2025 MJM 4 features twin Volvo 440 HP D6-DPI diesel engines very low hours with joystick docking for confident handling and remarkable efficiency. Built on a vacuum-infused epoxy composite hull with closed-cell foam coring, the MJM 4 delivers a lighter, stronger, quieter ride than many traditionally built competitors while maintaining exceptional offshore capability and best-in-class ride quality. Her modified deep-V hull and advanced engineering provide impressive stability underway and at rest, making long days on the water comfortable for guests of all ages.

The MJM 4 excels as a true luxury family day boat because she combines the social openness of a center console with the comfort, craftsmanship, and overnight capability of a premium express cruiser. Unlike many open day boats that compromise comfort for styling, the MJM offers a fully protected helm deck, a yacht-quality galley-up arrangement, and beautifully finished accommodations below featuring a spacious forward convertible berth, private midship berth, and a separate enclosed head with stall shower. Premium teak joinery, high-end soft-close cabinetry, synthetic teak decking, and thoughtful storage throughout elevate the onboard experience well beyond typical production brands.
