The 2025 MJM 4 is a 46-foot fiberglass bowrider built around a modern Downeast profile and advanced composite construction. Twin Volvo Diesel engines rated at 440 HP each deliver a top speed of 43 knots, with joystick docking for precision handling. The vacuum-infused epoxy composite hull with closed-cell foam coring provides a lighter, stronger, and quieter platform than traditionally built competitors, engineered to ISO Category B offshore standards.
The layout flows across four distinct social zones: a bow lounge, pilothouse, cockpit, and swim platform. The flush-deck walkaround design ensures safe passage throughout. The pilothouse features large opening side windows, electrically actuated forward glass, and an aft enclosure that transforms between open-air and weather-protected operation. An electrically adjustable dual helm with exceptional visibility commands the helm deck.
Below deck, accommodations include a forward convertible berth, a private midship berth, and a separate enclosed head with shower. The galley sits elevated and is equipped with dual refrigerator-freezer drawers and an induction cooktop. Interior joinery uses premium teak and cherry with soft-close cabinetry and synthetic teak decking. A convertible cockpit sun lounge, triple-position teak table, and generous storage complete the layout. Side and transom boarding doors provide multiple entry points to the large swim platform with retractable ladder.
Factory upgrades on this example include forward and aft cockpit covers, a bimini, LED smart televisions, a 43-inch pop-up galley television, Garmin GMR Fantom 18x radar, Sionyx Nightwave thermal camera, underwater transom lighting, and Stardust Metallic hull color.
