Manufacturer Provided Description

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 motor yacht worldwide to offer the "no roll" Seakeeper Gyro stabilizer 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.
