The MJM 50z is one of the most versatile boats ever built, offering speed, low maintenance and ease of use for dayboating and harbor cruising, while the generous accommodations, efficiency and seaworthiness make for an ideal long-range cruiser. There is no such thing as the perfect boat, but the 50z is about as close as you can get. The MJM has excellent design and build quality without heavy annual maintenance costs seen on similar boats.
Casta Diva is a well maintained, single-owner boat with summer use in New England and only a few winters down in Florida and the Bahamas. She is likely the best equipped MJM for long distance off-grid cruising with the 2 cabin/2 head layout, extended galley, separate washer and dryer, watermaker and dinghy setup.

MJM 50z: BoatTEST Review
Overview
The MJM 50Z represents a high-quality vessel designed to balance functionality for group entertaining near home with the capability for long-distance cruising, particularly suited for one or two couples. This boat emphasizes craftsmanship, thoughtful design, and practical features that enhance both comfort and usability on the water.
Exterior Design and Cockpit
Boarding the MJM 50Z from the transom reveals a spacious bench seating area that comfortably accommodates five people across, arranged around a teak table. This table is adjustable, allowing for easier dining arrangements while maintaining access to the swim platform gate and adjacent seating. The seating throughout the boat is upholstered in an indoor-outdoor ultra-suede leather, chosen for its durability, comfort, and cohesive aesthetic appeal. On the port side of the cockpit, there is a refrigerator with an optional grill installation available on top. The boarding step stands 27 inches above the waterline, facilitating convenient access from floating docks or tenders. Moving forward, the boat features opposing seating with storage beneath, including a starboard wraparound teak table that converts into a double berth with an additional single berth opposite, allowing three people to sleep on deck. Privacy curtains can enclose this area, and the entire deck is designed as a single-level surface with ample grab points for safety and ease of movement.
Helm and Navigation Area
The helm area is equipped with high-end, fully adjustable STIDD seats, including a double-wide captain's chair and an observer seat. The design prioritizes comfort and functionality for extended cruising, ensuring that both captain and companion have ergonomic seating and excellent visibility.
Interior Living Spaces
Below deck, the galley is positioned to port with a dining area to starboard. The dining area can convert into a berth, with privacy options including either a curtain or removable bulkheads, the latter featuring a nautical-inspired matte-finished cherry wood crafted from hand-stained single strips. The galley is thoughtfully designed for cruising life, featuring a single-basin stainless-steel sink with a pull-out sprayer, a faucet connected to a water purification system, refrigerated drawers, an ice maker supplied by purified water, and a two-burner stove with pop-up fiddles. A unique drying compartment allows dishes to air dry and drain overboard, eliminating the need for towel drying. All cabinetry and drawers exhibit dovetail joinery, emphasizing quality craftsmanship.
Private Accommodations and Heads
The guest head, which also serves as a day head, includes a solid-core door with a curved top and a full walk-in shower, providing comfort and convenience for visitors. The master stateroom offers complete privacy from the salon and features a door that folds flush against the bulkhead when open. The master head, located to port, matches the guest head in size but benefits from enhanced natural light and ventilation through two opening portlights and an overhead hatch. Storage is abundant with deep shelving, multiple cabinets, and under-sink compartments. A notable feature in the master stateroom is a comfortable sitting area with a small stool that can serve as a footrest or workspace, catering to extended cruising needs.
Storage and Practical Features
Storage capacity aboard the MJM 50Z is extensive and well-integrated throughout the vessel. The stateroom includes lockers on both sides and self-closing drawers beneath the berth capable of accommodating full-size luggage. The deck is finished with teak and holly covered by clear all-grip material rather than varnish, and synthetic seagrass carpeting enhances durability. Additional storage compartments are located in the deck and beneath steps, including specialized wine storage under seating and deep drawers with organizational features such as file folders for ship's papers. Remarkably, the in-deck storage is spacious enough to hold two bicycles, golf clubs, luggage, camping gear, and more, underscoring the boat’s suitability for extended cruising and varied activities.
Conclusion
The MJM 50Z is a meticulously crafted vessel that combines high-end finishes with practical design elements to support both entertaining and long-distance cruising. Its thoughtful layout, durable materials, and abundant storage make it a versatile and comfortable choice for couples or small groups seeking a premium boating experience. The boat’s balance of luxury and functionality reflects MJM’s commitment to quality and user-friendly design.
