MJM 50z

Our Boat Test of the MJM 50z. 

There are those who will tell you displacement speed is the most fuel-efficient way to travel. But back-of-the-envelope calculations may show you that the MJM 50z is the solution for the way you cruise.

Designing the MJM 50z

A boat like the MJM 50z doesn’t just fall from the heavens. It takes a whole lot of design ingenuity and hands-on know-how to build a boat like that. We went behind the scenes to show you exactly what it takes to build a boat.

Power & Motoryacht's first look at the MJM 50z. “The efficient 50z shares its genetics with the rest of the successful MJM fleet. The only drawback is the requirement of a bigger slip.”

While MJM’s boats sport a rather traditional Down East profile, a peek beneath the surface reveals innovation in nearly every aspect of the build, from her high-tech hull construction to a smart use of stern drives for a combination of performance, efficiency, and draft. 


Back in the early 1970’s Mary Johnstone raced 470 class sailboats in the “trapeze” position, often cantilevering herself completely outboard from a masthead wire to keep the jittery, planing 16-footer dry side up. Husband Bob steered, while two of their children raced another 470 and the other two stood by in an outboard in case either team’s weight-versus-wind balancing act went awry.
