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.

Overview
The MJM 40Z is a powerboat designed with input from sailboat designers, aiming to deliver exceptional fuel efficiency and performance for cruising couples. The design emphasizes lightweight construction combined with strength, and it is powered by twin Volvo Penta D6 engines paired with IPS 600 drives. This combination seeks to optimize fuel economy and handling, making the 40Z a notable contender among efficient cruisers.
Power and Performance
The MJM 40Z features two 435 horsepower Volvo Penta D6 engines driving IPS 600 pod drives. With an empty weight of 17,450 pounds and a test load of nearly 20,000 pounds including fuel and crew, the boat achieved a top speed of 40.2 knots at 3350 RPM. At this speed, fuel consumption was 44 gallons per hour, providing a range of approximately 288 nautical miles. The most economical cruising speed was found at 2250 RPM, delivering 20.6 knots while burning only 14 gallons per hour, extending the range to 464 nautical miles. Acceleration was notably quick, with the boat planing in just 4.4 seconds, reaching 20 miles per hour in 5.6 seconds, and 30 miles per hour in 8.6 seconds. Handling characteristics include a slight bow rise of about five degrees during acceleration and a cruising bow attitude of around four degrees. The boat demonstrated smooth passage through typical choppy conditions, maintaining stability and comfort.
Helm and Handling
The helm station is thoughtfully designed for cruising, featuring a 14-inch widescreen display, Raymarine autopilot, and depth gauge, all arranged for ease of use. The varnished destroyer wheel offers a light, responsive feel, complemented by adjustable footrests for operator comfort. Visibility is excellent due to the low and high window placement and the curved trunk cabin design, providing a panoramic view forward and around the boat. The helm offers clear sightlines to the foredeck and horizon, enhancing situational awareness. Turning performance is impressive for a pod-driven vessel, with a bank angle of approximately seven to eight degrees during tight turns at cruising speed. Maneuverability in close quarters is facilitated by a dynamic positioning system controlled via joystick, allowing for precise docking and single-handed operation.
Additional Features and Practicality
The 40Z includes practical features such as a chart table located behind the helm for manual navigation alongside electronic systems. Ventilation is well addressed with three front windows that open fully, ensuring comfortable airflow and mitigating greenhouse effects within the cabin. The boat’s design and systems support ease of handling for a cruising couple, with the ability to manage docking and line handling without assistance.
Conclusion
The MJM 40Z successfully combines the expertise of sailboat designers with advanced powerboat technology to deliver a fuel-efficient, high-performance cruiser tailored for couples. Its lightweight yet strong construction, efficient Volvo Penta IPS propulsion, and thoughtful helm layout contribute to an enjoyable and economical boating experience. The boat’s handling, visibility, and single-handed operation capabilities make it well suited for typical cruising conditions, offering both comfort and confidence on the water.
