Our Thoughts

The 2021 MJM 53z represents a rare ownership opportunity in the outboard-powered, long-range cruising segment. Built by Boston Boatworks and professionally maintained since delivery by Diaz Marine—Florida's longest-tenured MJM dealer and service provider—WELL DONE exemplifies the engineering and build quality that defines the MJM brand.

At 56.25 feet with a 15-foot beam and shallow 3.08-foot draft, the 53z delivers big-yacht comfort with the operational efficiency of outboard propulsion. Quad Mercury 300 hp Verado engines provide genuine 43-knot capability with the range and reliability that serious cruising demands. The shallow draft opens access to protected waters, shallow anchorages, and coastal destinations unavailable to deeper-hulled alternatives, while the composite construction and ISO CE Category A certification ensure seaworthiness and durability across ocean conditions.

The Great Cabin layout prioritizes cruising comfort and entertaining flexibility. The open salon and galley flow seamlessly, with the convertible Great Cabin table and L-lounge transforming into a full double berth for guest accommodation. Forward and aft cabin berths accommodate up to seven guests, making WELL DONE equally suited to couple cruising and extended family passages. The pilothouse provides all-weather helm comfort with opening electric windshields and fully-opening side windows, supported by a Seakeeper gyrostabilizer that dampens 93 percent of roll motion—a factory-standard feature that dramatically improves comfort at anchor and underway.

Helm systems reflect professional-grade cruising capability. Joystick docking and Skyhook station-keep simplify single-handed operation in tight quarters. A Raymarine electronics suite including dual Axiom Pro displays, a 16-inch primary screen, and a 12-inch co-pilot display provides integrated navigation, sonar, and system monitoring. The FLIR M232 infrared thermal camera mounted on a 10-inch Seaview pedestal with mast light integration enhances night navigation and situational awareness. KVH TV3 satellite television with Direct TV receiver keeps the crew connected during extended cruises.

Entertainment and comfort amenities reflect thoughtful ownership. A Fusion MS-AV755 stereo system with bass woofer, four pairs of speakers, and Sirius radio integration serves the salon and pilothouse. Multiple Smart TVs—a 29-32 inch HD display in the salon, a 22-inch LED in the forward cabin, and a 32-inch bridgedeck drop-down in the pilothouse—provide flexibility for entertainment and weather monitoring. A Kenyon electric grill on the aft serving bar, Esthec synthetic teak in the pilothouse and cockpit, and satin-varnished cherry paneling throughout establish a refined interior aesthetic. Three Hella turbo fans optimize cabin ventilation and comfort.

Deck and cockpit design prioritizes functionality and storage. The flush deck with side boarding doors simplifies guest boarding and movement. Aft deck storage locker and an electric aft cockpit Bimini with stabilizing bracket and boot storage provide weather protection and operational flexibility. Two transom rod holders with a double overhead rod rack to starboard accommodate fishing pursuits. A side-door swim and dive ladder, Chelsea clock and barometer, and co-pilot window controls with custom electric pilothouse shades complete the equipped package.

Fuel capacity of 920 gallons and water capacity of 250 gallons support extended blue-water cruising without frequent provisioning stops. The extended Mercury warranty coverage reflects the

2021 MJM 53z Outboard: Premium Coastal Cruiser with Great Cabin Layout and Seakeeper Stabilization
The 2021 MJM 53z stands as one of the finest examples of modern fiberglass cruising design, combining the shallow-draft efficiency of quad outboard propulsion with the comfort and seaworthiness expected of a true ocean-capable yacht. Built by Boston Boatworks and located in Miami , Florida, this 56.25-foot vessel represents a thoughtfully equipped platform for extended cruising, day boating, and entertaining, backed by professional Diaz Marine service since delivery.
Overview: Design Philosophy and Build Quality
MJM Yachts has earned recognition for engineering boats that balance performance, comfort, and practicality. The 53z model embodies that philosophy through its light, high-tech composite construction, which reduces weight while maintaining structural integrity and ISO CE Category A ocean certification. At 56.25 feet in length with a 15-foot beam and 3.08-foot draft, the 53z achieves the shallow-water capability that appeals to cruisers who value access to protected anchorages, coastal bars, and remote destinations without sacrificing the stability and accommodations of a larger yacht. The hull shape delivers what MJM describes as "tremendous stability and sportscar response," a combination enabled by the boat's carefully refined lines and the optional Seakeeper gyro stabilizer, which dampens 93 percent of roll motion even when docked. For a vessel in this size range, that level of motion control transforms the cruising experience, particularly for those sensitive to rolling or for entertaining guests in challenging sea states.
Layout and Deck Design: The Great Cabin Advantage
This particular 53z is configured with the "Great Cabin" layout, a factory option that prioritizes open, flowing interior space over traditional forward cabin separation. This arrangement creates a unified salon and galley area, ideal for cruising couples who value sightlines, natural light, and the ability to socialize while preparing meals or managing navigation. The cabin converts to a full double berth when needed, expanding sleeping capacity without the constraints of a dedicated forward stateroom. The vessel sleeps seven comfortably across its berth configuration, which includes the convertible Great Cabin double, a forward cabin with a 22-inch LED smart television, and additional guest berths, making it suitable for small-group cruising or entertaining family and friends. The pilothouse includes a drop-down 32-inch television over the companionway, reinforcing the integration of modern entertainment with traditional yacht functionality. Deck design emphasizes usability and safety. The flush-deck layout minimizes obstacles and improves sightlines from the helm. Side boarding doors provide convenient access from dock or tender, while an aft deck storage locker accommodates gear, fenders, and provisioning. The aft cockpit features a Bimini top that rolls up into a sailboat-style boot, preserving the clean lines of the hardtop while providing shade for entertaining or relaxing at anchor. A Kenyon electric grill mounted on the aft serving bar supports al fresco dining and adds functionality to the aft entertaining space. Two rod holders on the transom and a double overhead rod rack to starboard reflect the boat's capability for light fishing or sport fishing pursuits, though the primary design intent is coastal cruising rather than dedicated offshore fishing.
Helm and Electronics: Advanced Navigation and Control
The helm station is engineered for comfort and capability during extended passages. Opening electric windshields and fully-opening side windows provide ventilation and visibility while maintaining weather protection. Custom electric pilothouse side window shades offer privacy and glare control. The joystick control system simplifies docking and station-keeping, particularly valuable in tight anchorages or when maneuvering single-handedly. The electronics suite reflects a modern, integrated approach to navigation and situational awareness. The primary helm features a Raymarine Axiom Pro 16s multifunction display, flanked by a portside co-pilot Axiom Pro 12s and an i70s multi-function controller. This redundancy ensures navigational continuity and allows crew coordination during passages. An additional surface-mount Axiom Pro 16s display provides secondary helm capability or dedicated chart-plotting functionality. A FLIR M232 infrared camera mounted on a 10-inch Seaview pedestal with a mast light on a hinge-down mounting plate adds thermal imaging capability, valuable for night navigation, identifying other vessels, or assessing weather patterns. The Raymarine ecosystem integrates radar, autopilot, and sonar functions, creating a cohesive digital helm environment. Satellite television is supported through a KVH TV3 Direct TV receiver dome on a pedestal, which also houses radar and navigation lighting. Entertainment is managed through a Fusion MS-AV755 stereo system with bass woofer, four pairs of speakers, and Sirius Radio integration, allowing music throughout the pilothouse and salon. Co-pilot window controls enable port and center window operation from the secondary helm position, reducing the need to move between stations during docking or tight maneuvering.
Cabin and Interior: Comfort and Accommodation
The interior reflects a balance between yacht elegance and practical cruising functionality. Satin-varnished cherry paneling in lieu of off-white laminate (except in heads) adds warmth and visual richness to the main salon and pilothouse. This finish choice is particularly notable in the Great Cabin layout, where the unified space benefits from cohesive interior styling. Climate control is managed through three Hella turbo fans positioned over the forepeak berth and in the second cabin, supplemented by the open-window design that allows natural ventilation. The pilothouse's all-weather comfort is reinforced by the opening windows and electric shades, creating a flexible environment that can be sealed for rough weather or opened for light-air sailing. The galley is integrated into the Great Cabin layout, supporting meal preparation and provisioning for extended cruises. Fresh water capacity of 250 gallons supports typical cruising ranges without requiring frequent refill stops, while the 920-gallon fuel capacity extends range and reduces the need for frequent fuel stops. Two heads provide the sanitation infrastructure expected for a seven-person cruising platform, with adequate privacy and storage. A Chelsea clock and barometer mounted in the Great Cabin add both functional time-keeping and aesthetic character.
Power and Performance: Quad Mercury Verado Outboards
The 53z is powered by quad Mercury 300 horsepower Verado outboards, delivering 1,200 total horsepower. This outboard configuration offers several advantages over inboard propulsion: shallow draft (3.08 feet), ease of maintenance and service, the ability to trim up in shallow water, and the flexibility to tilt out when beached or anchored in very shallow conditions. The manufacturer cites a 50 mph top speed, though actual performance varies with load, fuel state, sea conditions, and trim. The outboard configuration also provides redundancy; loss of a single engine does not compromise the vessel's ability to return to port or reach shelter. The quad setup distributes power across four units, reducing individual engine strain and potentially extending service intervals. Mercury extended warranty coverage has been extended from the standard two years to five years, reflecting the owner's commitment to long-term maintenance and providing incoming buyers with extended manufacturer support.
Equipment Highlights and Options
This 53z includes a comprehensive suite of factory options that enhance comfort, functionality, and entertainment value: Exterior and Deck : Esthec synthetic teak in the pilothouse and cockpit provides the appearance and tactile quality of natural teak without the maintenance demands. The aft cockpit Bimini with stabilizing bracket and sailboat-style boot storage maintains clean lines while providing shade. The transom rod holders and double overhead rack support fishing pursuits or simply provide secure storage for fishing rods during transit. Entertainment and Connectivity : The three integrated smart televisions (32-inch primary in the salon, 22-inch in the forward cabin, and 32-inch drop-down in the pilothouse) support streaming, satellite television, and entertainment throughout the vessel. The Fusion audio system with Sirius Radio integration provides music and news throughout the pilothouse and salon. The KVH satellite receiver enables Direct TV reception at anchor or underway. Navigation and Imaging : The Raymarine Axiom Pro multifunction displays and the FLIR thermal camera create a modern, integrated helm environment suitable for night navigation, passage planning, and situational awareness.

What type of boat is the MJM 53z and what makes it suitable for offshore cruising?
The MJM 53z is a 56-foot outboard-powered cruising yacht built by Boston Boatworks, designed for both offshore capability and comfortable extended cruising. The boat carries ISO CE Category A ocean certification, meaning it's engineered to handle open ocean conditions. The shallow 3.08-foot draft combined with a 15-foot beam provides excellent stability and allows access to shallow-water anchorages that deeper-draft yachts cannot reach. The "Great Cabin" layout prioritizes comfort for cruising couples while accommodating guests, making it well-suited for those who want to spend extended time aboard exploring different regions.
What is the engine configuration and how does it perform?
The MJM 53z is powered by quad Mercury 300 hp Verado outboards, delivering 1,200 total horsepower. This outboard package provides a 50 mph top speed and 43.45-knot capability, offering strong performance for a 56-foot yacht while maintaining the operational advantages of outboard propulsion—easier maintenance, no through-hull shaft seals, and the ability to trim up in shallow water.

How does the Seakeeper gyro stabilizer improve the cruising experience?
The Seakeeper gyrostabilizer, which is standard on this vessel, dampens 93 percent of roll motion, even when the boat is at rest at the dock. This technology is particularly valuable for cruising couples and those prone to motion sensitivity, as it dramatically reduces the side-to-side movement that can cause discomfort during extended offshore passages or when anchored in beam seas. The stabilizer allows for a more comfortable night's sleep and reduces fatigue during longer cruising days.
What is the cabin layout and sleeping capacity?
The MJM 53z features the "Great Cabin" layout with sleeping capacity for seven people comfortably. The main salon includes a convertible double berth with privacy curtain, the forward cabin has a dedicated berth, and there are additional guest berths available. The salon galley is open and integrated with the living space, making it ideal for cruising couples who want an airy, connected interior rather than a closed-off galley. The convertible salon berth provides flexibility for either entertaining guests or creating additional sleeping space as needed.
What navigation and electronics are installed on this vessel?
The yacht is equipped with dual Raymarine Axiom Pro multifunction displays at the helm—a 16-inch primary display and a 12-inch co-pilot display—along with an i70s multi-function controller for easy navigation management. Additional electronics include a FLIR M232 infrared thermal camera mounted on a 10-foot Seaview pedestal for enhanced visibility in low-light conditions, and a KVH TV3 satellite receiver with dome antenna that includes radar and navigation light integration. This electronics suite provides comprehensive navigation capability, weather awareness, and advanced situational awareness for offshore cruising.
How is the helm station configured for comfort and control?
The pilothouse features all-weather comfort with opening electric windshields and fully-opening side windows that allow for natural ventilation and visibility. The helm includes joystick control for intuitive maneuvering, Skyhook station-keep capability to hold position automatically, and co-pilot window controls for the port and center windows. The pilothouse is equipped with a 32-inch drop-down TV over the companionway, and custom electric window shades provide glare control. A secondary Axiom Pro 12s display is mounted at the co-pilot position, allowing a passenger or second operator to monitor navigation independently.
What entertainment and media systems are available aboard?
The yacht includes a comprehensive entertainment setup with a primary 29- to 32-inch HD smart TV in the main salon, a 22-inch LED smart TV in the forward cabin, and the 32-inch pilothouse display that can serve dual purposes. A Fusion MS-AV755 stereo system with bass woofer, four pairs of speakers, and Sirius satellite radio provides audio throughout the vessel. The KVH satellite TV receiver allows access to Direct TV programming, and the system supports connectivity for streaming content when docked at marinas with internet access.
What deck and cockpit features support entertaining and outdoor living?
The aft cockpit includes a Kenyon B70057 electric grill mounted on the aft serving bar, making it convenient to prepare meals while entertaining guests topside. An aft cockpit Bimini top with stabilizing bracket rolls up for storage in a boot on the aft upper hoop, providing sun protection when deployed. Two rod holders are mounted on the transom with a double overhead rod rack to starboard over the settee. The flush deck and side boarding doors facilitate easy access and movement around the boat, while the aft deck storage locker provides space for cruising gear, fenders, and dock lines.
What ventilation and climate control systems are integrated into the design?
The vessel is equipped with three Hella Turbo fans strategically positioned over the forepeak berth and in the second cabin to ensure adequate air circulation throughout the interior spaces. The opening electric windshields and fully-opening side windows in the pilothouse provide natural ventilation and allow occupants to control air exchange based on weather and preference. This multi-zone ventilation approach helps maintain comfortable interior temperatures during warm-weather cruising and prevents moisture buildup in closed cabins.
What construction materials and design features contribute to the vessel's durability?
The MJM 53z utilizes light, high-tech composite construction that reduces weight while maintaining structural integrity and longevity. Interior finishes on this particular vessel include satin varnished cherry paneling in the main spaces rather than standard off-white laminate, providing a warm, refined aesthetic. The hull is finished with Pettit 1869 "Black Widow" vivid bottom paint for corrosion protection and visibility. The boat features a side-door swim and dive ladder for water access, and includes a Chelsea Clock and barometer mounted in the Great Cabin as functional décor elements that reflect the quality of the build.
What maintenance and dealer support history does this vessel have?
This MJM 53z has been professionally maintained by Diaz Marine since delivery, Florida's longest-tenured MJM dealer and service provider. The boat has been kept in like-new condition through consistent professional care, and the engines are covered by Mercury extended warranty extended from the standard 2 years to 5 years. Access to factory-authorized service through an established dealer ensures that parts, technical support, and warranty work can be addressed promptly, which is a significant advantage for outboard-powered yachts that require regular engine maintenance and seasonal service.
