All New MJM 4 Crossover Day and Cruising Performance Yacht


Washington, N.C. – October 8, 2021 – Family-owned and-operated MJM Yachts introduces its latest high-tech performance yacht: the all-new MJM 4. Described as the “Evolution of the Day Yacht,” the MJM 4 made its world debut today at a press conference held at the United States Boat Show in Annapolis, Md.


MJM Yachts are world-renowned for their timeless style, advanced precision epoxy composite construction, comfort, and best-in-class sea handling. The new MJM 4 is a blend of the highly popular MJM 3 Dual Console and the boat that many say is the best all-around liveaboard express cruiser ever produced, the MJM 40z.

With an LOA of 46’ 8”, the MJM 4 is an impressive new crossover model designed as a day yacht featuring four social zones and galley-up layout, as well as offering overnight accommodations. The galley-up design is a first for MJM, but it’s a common-sense layout that keeps everyone at the center of the action.

MJM 4 cabin layout

The open bow and aft cockpit offer spacious, secure outdoor seating, while the indoor/outdoor pilothouse provides protection from the elements. Electrically activated windshields, sliding side windows and back all open effortlessly for a partly or completely open-air voyage. Just as swiftly, you can button up the pilothouse when inclement weather threatens, while maintaining a 360-degree view. The result is not only expanded comfort, but an extended boating season.

Below deck is a large V-berth and a double berth amidships, just right for a couple of couples. Special attention has been dedicated to the yacht-sized head with glass enclosed shower.

With this innovative layout, 50-mph performance, and exceptional stability, the MJM 4 is redefining performance yachting.

The MJM 4 will initially be offered with the option of triple 300-hp Mercury outboards or twin 600-hp Mercury Verados. Twin 440-hp Volvo DPI sterndrives will be offered for the 2024 model year.
