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" Sea Keeper 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.
