2025 MJM 42

The MJM 42 is a 47-foot composite-hulled downeast cruiser built for offshore capability and refined performance. At 12 feet in beam, the yacht balances seaworthiness with livable interior volume, combining classic downeast design principles with contemporary engineering and construction standards.

Powered by Mercury engines, the MJM 42 delivers the efficiency and reliability expected in a modern cruising yacht. The design emphasizes both comfort for extended passages and the practical features that serious boaters require when operating beyond protected waters.
