Because MJMs are built to the standards of the International Marine Certification Institute, they are certified to the highest possible rating, Category A Ocean and Category B Offshore, where stability and driving control are heavily weighted.  Stability is critical in a powerboat’s ability to handle the varied conditions of offshore cruising.

The design of MJMs with their low vertical center of gravity and the dynamic stability created underway by the hull shape give MJMs the exceptional sea keeping ability not found in other yachts.
