The 2025 MJM 42 brings a spirit of adventure and luxury to Boston Harbor boating. Powered by twin Volvo 440 HP D6-DPI 6-cylinder engines and equipped with both a responsive bow thruster and a gyro stabilizer, this MJM delivers smooth handling whether navigating choppy open waters or docking in lively marinas. Its suite of advanced navigation equipment—including the Garmin GPSMAP 16" chart plotter, Fantom 18x radar, Mercury Vessel View onboard trip display, VHF & AIS radio, and a Sionyx Nightwave thermal camera—makes cruising day or night a confident, high-tech experience as you chart your course from the heart of Boston to hidden gems in Massachusetts Bay.
The MJM 42 stands out with elegant yet practical exterior features, led by a Flag Blue hull that gleams against the city skyline and classic synthetic teak flooring that withstands salt and sun. Cruising past the iconic Zakim Bridge, guests can relax under the generous aft cockpit shade system or gather in the cockpit’s easy-access design with side and transom entry doors. Stainless steel bow railings and custom cleats ensure security and style whether you're tying up at Spectacle Island or heading out toward the North Shore.
Step inside, and you’ll find a welcoming cabin tailored for entertaining and comfort. The plush black seam/tusk cushion upholstery sets a refined tone, complemented by a C-shaped lounge to port and a functional galley to starboard for culinary pursuits. A smart lighting package—featuring underwater lights and a 24" LED TV in the bow stateroom—sets the perfect ambiance for evenings anchored near Boston Light. Climate control keeps the interior comfortable year-round, with air conditioning and whisper-quiet 12V fans over the master berth and midship cabin. Modern vanity cabinets, a solid surface countertop, and a fully enclosed head and shower round out the luxury touches.
From the vibrant city waterfront to the historic harbor islands, the MJM 42 is perfectly suited for Boston’s boating playground. Its blend of performance, technology, and comfort turns every excursion—whether a lunch cruise with friends or a weekend escape with family—into a signature experience. With this MJM, every local landmark is just a course away, and every trip is enhanced by the vessel’s thoughtful options and effortless style.

The 2025 MJM 42 is engineered for discerning owners who value elegance, cutting-edge technology, and the ability to cruise in comfort throughout New England. Thoughtful amenities shape every detail: from year-round climate control to advanced navigation and entertaining spaces.
