2025 MJM 4

The 2025 MJM 4 is a 46-foot motor yacht that brings together American yacht design tradition with modern composite construction and high-performance engineering. Built on a vacuum-infused epoxy composite hull with closed-cell foam coring, the boat delivers a lighter, stronger, and quieter platform than traditionally built competitors while maintaining offshore capability. Twin Volvo D6-DPI diesel engines producing 440 horsepower each power the yacht to a maximum speed of 50 knots, with joystick docking for confident boat handling.

The design centers on four distinct social zones flowing from bow lounge through the pilothouse to the cockpit and swim platform. The flush-deck, walkaround layout provides safe movement throughout, while the innovative pilothouse combines indoor and outdoor functionality—large opening side windows, electrically actuated forward glass, and aft enclosure create an open-air experience or climate-controlled environment as needed. An electrically adjustable dual helm seating arrangement offers exceptional visibility and command of the yacht.

Below deck, accommodations include a spacious forward convertible berth, private midship berth, and an enclosed head with stall shower. The galley is positioned up, featuring dual refrigerator/freezer drawers and an induction cooktop. Premium teak and cherry joinery, soft-close cabinetry, and synthetic teak decking throughout reflect yacht-quality craftsmanship and thoughtful storage design.

Factory upgrades on this example include forward and aft cockpit covers, a bimini top, removable bow table, multiple smart televisions, a 43-inch pop-up TV in the galley, thermal imaging, Garmin radar, underwater transom lighting, and a 120V electric grill on the serving bar. The yacht features triple-position teak tables, a convertible cockpit sun lounge, side and transom boarding doors, and a large swim platform with retractable ladder. The hull is finished in Stardust Metallic, and the yacht is rated for offshore use under ISO Category B standards.
