  • 2017 MJM Yachts 40z Hull #74


The MJM Yachts 40z is an eco-smart, thoughtfully created game-changer built with advanced composites, having an innovative layout and superior handling. Her strong, lightweight wet pre-preg, post-cure, epoxy/Eglass/Corecell hull results in a very low center of gravity, which translates into greater stability and seaworthiness as well as an impressively comfortable ride. Along with the Nordhavn 40, she is one of only two 40’ yachts ISO Certified Category A Ocean. Her optional Seakeeper gyrostabilizer guarantees “no roll” comfort and less fatigue. Adding further to gracious living is the flush deck from cockpit to helm, combined with side boarding doors at floating dock height. Gone are the many upstairs, downstairs and boarding challenges encountered on other yachts. That large deck for entertaining, fully-opening front windshields, panoramic sightlines and a uniquely open galley with dinette below are real eye-openers in terms of space utilization and ventilation. But to many, 40z’s greatest attribute is how she drives.
