This MJM Yacht is a new boat, but it is also being offered for sale as brokerage.
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.

Overview
The MJM 40Z is a 43-foot luxury cruiser designed in the classic down east style, emphasizing both comfort and refined aesthetics. Crafted to accommodate social gatherings and extended cruising, the vessel features three distinct gathering areas, with two well-appointed spaces on the main deck. The design and material choices reflect MJM's commitment to quality and functionality, making the 40Z suitable for both entertaining and comfortable living aboard.
Exterior Design and Deck Layout
The cockpit serves as the primary outdoor entertainment area, welcoming guests with easy access via opening side doors on both port and starboard sides, facilitating boarding from floating docks or tenders. Seating arrangements include a four-person bench at the stern facing two double-wide aft-facing seats, comfortably accommodating eight guests for conversation or dining when paired with a pedestal table. Safety is addressed with 29-inch high, 1.25-inch stainless steel guard rails around the cockpit. Forward on the bow, 29-inch high rails angled outward provide clear sight lines, complemented by a standard 400,000 candlepower spotlight mounted atop the forward rail. Anchoring equipment includes a Muir windlass with deck and helm controls, a polished stainless steel Lumar claw anchor with 250 feet of rode and 25 feet of stainless chain, and a fresh water anchor and rode washer to maintain cleanliness during retrieval. The bow is further protected by a polished stainless steel guard.
Pilot House and Social Spaces
The pilot house is designed to balance cruising functionality with social engagement. Dual opposing couches create an intimate seating area around a finished teak table equipped with raised fiddles when folded. Storage beneath the seats is notably spacious, capable of housing large items such as bicycles, golf clubs, or a life raft. Safety and convenience are enhanced by strategically placed handrails throughout the space. The helm features two Stidd Admiral low-back piloting chairs upholstered in ultra-leather, each 30 inches wide with flip-down armrests, swiveling bases, and telescopic pedestals, allowing them to pivot and increase seating capacity to eight. The helm console includes a 24-inch destroyer wheel with a varnished teak rim and a bi-level anti-glare instrument panel capable of accommodating a full suite of navigational electronics. A dedicated navigation station to port offers a 27 by 17-inch angled surface suitable for an additional chart plotter, while a companionway hatch doubles as a chart table with grab handles. The pilot house windshield is framed in molded Downeast style with a hardtop, allowing windows to open fully for ventilation. The enclosure can be completed with strata glass windows or an optional express glass surround.
Interior Living Spaces
Below deck, the layout is optimized for cruising couples, featuring a private forward stateroom ahead of the galley and dinette. The companionway includes larger, stair-like steps with storage lockers beneath each step. The interior sole is teak and holly finished with a durable clear all-grip coating, providing 6 feet 4 inches of headroom at the centerline. The dinette offers booth-style seating with an electrically lowering table that converts into a berth, with convenient storage compartments between seats that include a 110-volt outlet and MP3 port. The paneling is finished in off-white Nevermar HPL accented with cherry trim and a foam-backed vinyl headliner with satin varnish cherry ceiling battens. The galley, located to port, features Corian countertops and cherry cabinetry designed for full-size dinnerware. The recessed polished stainless steel sink includes a removable Corian cover and a Skanvik pullout faucet. Cabinetry is highly functional with lockable, dovetail-joined drawers sealed against moisture, dedicated flatware drawers, and a dry goods cabinet with sliding doors and LED lighting. A separate rinsing compartment with drain and vent is positioned outboard of the sink. Safety and practicality are further enhanced by an overhead grab rail and a raised lip on the upper shelf to provide secure handholds in rough conditions.
Private Accommodations and Heads
The forward cabin provides a private retreat with a 78 by 60-inch island double berth featuring a quilted ultra-leather memory foam mattress and ample storage beneath. Above the berth, a well-crafted shelf doubles as a handrail to assist in exiting the berth. The cabin includes a combination bureau and entertainment center with a Corian countertop and a hanging locker to port. Privacy is afforded by a full-length mirror on the door, which closes off the stateroom. The wet head is accessible from both the stateroom and salon, allowing it to function as a day head. It features a Corian countertop with a polished stainless steel oval sink and a pull-out hose for use as a soft spray shower. Additionally, a separate shower compartment on the starboard side allows two people to prepare simultaneously, enhancing convenience for evening plans.
Conclusion
The MJM 40Z exemplifies premium cruising design with meticulous attention to materials, craftsmanship, and practical features. Its multiple social areas, well-thought-out interior layout, and robust exterior appointments make it a versatile and comfortable vessel for extended cruising and entertaining. The combination of quality construction, functional design, and refined aesthetics underscores MJM's reputation for building upscale, user-focused cruising boats.
