The MJM 40z
An Agile Performer for a Stable ride
The 40z is an agile performer that parts the waves cleanly and deflects the wave action down and away for a soft, dry and stable ride. Fast, fuel efficient and ISO Category A Ocean certification distinguish the 40z as the undisputed best-in-class. Based on light but exceptionally strong epoxy construction and narrow, effective hull design, the 40z can best the competition by as much as 50% improvement in nautical miles per gallon at higher cruising speeds.

Think of the MJM 40z layout as an airy summer porch: open side windows and windshields, an expansive bimini to shade the cockpit.
