The MJM 50z is an eco-smart game-changer featuring advanced composite construction, an innovative layout and the latest stabilizing technology. Her stronger, lightweight epoxy construction results in a very low vertical center of gravity. That translates into greater stability, ISO-certified Category A seaworthiness, and an impressively comfortable ride. MJM 50z was the first motoryacht worldwide to offer the "no roll" Seakeeper Gyrostabilizer as standard equipment. Adding further to comfort and livability: Her flush-deck layout from cockpit to helm combined with side boarding doors at floating dock height eliminates the many up-downs and boarding access challenges of other yachts.

You want to look at your boat with pride and know you own a work of art. A boat that draws compliments on entering the harbor—not a "here today and gone tomorrow" styling. That's why Doug Zurn was chosen as the designer. He has the best eye in the business and created the Shelter Island 38 for singer Billy Joel. A U.S. design patent protects that unique MJM signature look. There are other important benefits of the 50z's sleek profile: Lower bridge clearance, greater stability for seaworthiness, faster hose-down after use, less windage and easier trucking overland.
