Our Thoughts
Written by The Fly Yachts Team · Brokerage

LOLA is a 2018 MJM 50z, a purpose-built cruising motor yacht designed by Doug Zurn and constructed by Boston Boat Works. This one-owner vessel represents the thoughtful engineering and quality execution that define the MJM brand—a platform engineered for owner-operator confidence, extended cruising, and genuine comfort in variable sea conditions.

Propulsion and Performance

Triple Volvo Penta IPS 600 inboard engines (435 hp each) power LOLA with joystick control, Skyhook station-keeping, and integrated Volvo autopilot. The IPS pod-drive configuration delivers a 35-knot cruise and 40-knot top speed while maintaining the quiet, fuel-efficient operation that makes long-distance cruising genuinely pleasant. Dual joystick controllers—one port, one starboard—eliminate traditional wheel steering in favor of intuitive, fingertip maneuvering and seamless docking in tight quarters. Seakeeper 9 gyro stabilization and Humphree interceptor trim tabs work in concert to reduce roll and pitch, materially improving comfort and reducing fatigue during extended offshore passages or rough-water transits.

Layout and Accommodations

The interior follows MJM's well-proven 50z design philosophy: a bright, open bridge deck serving as the social and operational heart, with a flexible below-deck layout that adapts to owner preference. The helm station features 360-degree visibility through push-button opening windshields and roll-up Strataglass enclosures, wide side decks with stainless grab rails, and protected side doors—all hallmarks of serious cruising design. Stidd helm seating and port/starboard settees create a command center that feels both functional and inviting.

The forward stateroom includes a centerline island berth with Ultraleather trim, dual hanging lockers, and ensuite access to dual heads. Two enclosed showers with molded seats, overhead hatches, and portlights provide genuine privacy and comfort. The salon/great cabin features convertible seating that transforms into sleeping berths and connects directly to a well-appointed galley three steps below the bridge deck. A portable cherry wall system allows the starboard area to convert into a private guest cabin with ensuite head access—a flexible solution for mixed-use cruising and entertaining.

Sixteen opening ports and hatches flood the interior with natural light and ventilation, creating an airy, open feeling rarely achieved on a 50-foot motor yacht. Teak-and-holly sole, cherry cabinetry throughout, and Corian countertops reflect thoughtful material selection and consistent aesthetic execution.

Galley and Provisioning

The galley includes a Vitrifrigo 2-drawer stainless refrigerator, top-loading Isotherm freezer, ceramic 2-burner electric cooktop with retainers, convection/microwave oven, and a stainless sink with spray faucet. Ample pantry storage, under-counter lockers, and a dish-drying locker with drain and vent support extended cruising and entertaining. Abundant deck lockers accommodate kayaks, bicycles, golf clubs, and long-haul gear—a practical recognition that cruising vessels serve as floating basecamp for active owners.

2018 MJM 50z LOLA: A One-Owner Volvo IPS Triple-Engine Cruising Yacht Built for Effortless Offshore Performance
The 2018 MJM 50z represents one of the most thoughtfully engineered express cruising yachts in the 50-foot class, and LOLA exemplifies the breed at its finest. Built by Boston Boat Works and designed by Doug Zurn, this one-owner vessel combines triple Volvo Penta IPS 600 propulsion, integrated stabilization systems, and a bright, convertible interior layout that prioritizes both owner operation and social entertaining. Priced at $1,665,000 and located in West Palm Beach , Florida, LOLA offers the operational simplicity, comfort, and range that serious cruising owners demand.
Overview: Design Philosophy and Build Quality
The MJM 50z emerged from a collaborative design process between Doug Zurn and Boston Boat Works, focusing on owner-friendly operation, fuel efficiency, and comfortable offshore cruising. LOLA's one-owner history and meticulous maintenance record reflect the care that this design philosophy encourages. At 50 feet in length with a 15-foot beam and 3.83-foot draft, the 50z balances seakeeping capability with the shallow-water access that appeals to cruisers exploring coastal destinations and gunkhole anchorages. The yacht's exterior presents in Moonglow Silver Awlcraft 2000 topsides with a Claret cove stripe, paired with Esthec decking in biscuit tone and white seams. This color combination and material selection support both aesthetic appeal and practical maintenance—Awlcraft provides UV protection and durability, while Esthec decking resists staining and delivers a warm, inviting appearance that complements the yacht's modern styling. Wide side decks with stainless grab rails and dual side entry doors facilitate safe movement around the vessel and provide convenient boarding from the water or dock.
Helm and Deck Design: 360-Degree Visibility and Joystick Control
The helm station exemplifies MJM's commitment to owner-friendly operation. Positioned forward on the bridge deck with 360-degree visibility through push-button opening windshields and roll-up Strataglass enclosures, the helm offers unobstructed sightlines in all directions. Stidd helm seating provides ergonomic support during long passages, while port and starboard settees create a social bridge deck that functions equally well as a cruising command center or entertaining space. The steering system centers on dual joystick controllers integrated with Volvo Penta's advanced docking and station-keeping technology. Two independent joystick stations allow intuitive maneuvering in tight quarters, marina approaches, and challenging anchorages. Paired with Skyhook station-keeping capability, the joystick system enables LOLA to hold position without anchor deployment—a significant advantage in crowded anchorages or when brief stops are needed for water activities. Glendinning 50-amp shore power with remote reel simplifies dockside connections, while a Muir anchor windlass with Ultra anchor and stainless steel chain supports confident anchoring in a variety of seabeds. Custom stainless dive ladders and grab handles, along with a stowable swim ladder that nests beneath the swim platform, facilitate water access for swimming, snorkeling, or diving operations. A transom door opens directly to the swim platform, creating a natural flow between the saloon and water-based activities.
Propulsion and Performance: Triple Volvo IPS 600 Efficiency
LOLA's propulsion package consists of three Volvo Penta IPS 600 engines, each producing 435 horsepower and powered by D6 diesel blocks. The IPS (Inboard Performance System) configuration integrates the engines with a pod drive that rotates 360 degrees, eliminating the need for a traditional rudder and delivering superior maneuverability. The triple-engine setup distributes power across three independent propulsion units, improving redundancy and allowing single-engine cruising if needed. At 35 knots, LOLA cruises at a whisper-quiet pace that conserves fuel while maintaining sufficient speed for practical passage-making. The maximum speed of 40 knots is achievable with all three engines at full throttle, offering capability for time-sensitive transits. With a fuel capacity of 520 gallons and cruising speed of 35 knots, the yacht supports extended offshore passages and long-range cruising without frequent refueling stops. Humphree interceptor trim tabs provide dynamic pitch and roll control, automatically adjusting the yacht's attitude to optimize ride quality, fuel efficiency, and comfort underway. These tabs work in concert with the Seakeeper 9 gyro stabilizer, a gyroscopic stabilization system that dramatically reduces roll motion in beam seas. The combination of Humphree tabs and Seakeeper gyro creates an exceptionally smooth ride that allows passengers to remain comfortable and active during passages in moderate sea states—a capability that distinguishes LOLA from conventionally stabilized vessels.
Comfort and Seating: Bridge Deck and Social Entertaining
The bridge deck functions as the social heart of LOLA. The open layout connects the helm station with port and starboard settees, creating an integrated entertaining space that encourages conversation and shared experience. Removable teak cockpit and pilothouse tables allow flexible furniture arrangement, transforming the space from a formal dining configuration to casual seating suitable for cocktails and socializing. The roll-up Strataglass enclosures seal the bridge deck against wind and spray while maintaining visibility and light, extending the usable season and protecting passengers from weather. Wide side doors with secure latching provide safe, convenient access to the side decks without negotiating companionways or confined passages. This design philosophy prioritizes accessibility and safety—a hallmark of Doug Zurn's approach to cruising yacht design. Exterior storage includes dedicated lockers for kayaks, bicycles, and golf clubs, along with custom sunshades that attach seamlessly to the Bimini to create a full enclosure of the sundeck. Kayak racks mounted on the cabin top with handholds provide secure stowage while maintaining access for quick deployment. These features support the extended cruising lifestyle that appeals to active owners seeking water-based adventures and outdoor entertaining.
Galley and Provisions: Full-Service Cooking and Storage
The galley sits three steps below the bridge deck and integrates seamlessly into the great cabin, creating an open, bright space that functions as both a working kitchen and social hub. Corian countertops with cherry cabinetry provide a warm, durable work surface, while a stainless Vitrifrigo two-drawer refrigerator and top-loading Isotherm freezer ensure ample cold storage for extended cruising. A ceramic two-burner electric cooktop with retainers, convection/microwave oven, and stainless sink with spray faucet support full meal preparation, while a dish drying locker with drain and vent simplifies cleanup. Ample pantry and under-counter storage accommodate provisions for multi-week passages, reducing the need for frequent provisioning stops. This generous galley storage, combined with the yacht's 150-gallon fresh water capacity and robust electrical systems, supports self-sufficient cruising in remote anchorages and extended offshore passages.
Cabin and Interior Accommodations: Convertible Layout and Natural Light
LOLA's interior design maximizes natural light and ventilation through sixteen opening ports and hatches distributed throughout the vessel. This commitment to natural illumination and fresh air circulation creates an inviting atmosphere that reduces reliance on artificial lighting and mechanical ventilation during pleasant weather—a design choice that enhances both comfort and operational efficiency. The forward stateroom features a centerline island berth with Ultraleather trim, dual hanging lockers, and storage drawers. Ensuite access to dual heads with matching enclosed showers provides private facilities, while overhead hatches flood the cabin with natural light and allow fresh air circulation. The centerline berth positioning improves motion comfort in rough seas, as the vessel's center of roll experiences less amplitude than off-center berths. The great cabin includes a convertible seating configuration that can transform into twin or double berths, accommodating guests with flexibility and privacy. A dining/coffee table with adjustable pedestal supports meals and socializing, while built-in storage drawers beneath settees maximize interior volume. The convertible guest cabin option uses a custom cherry wall system that slides into place and locks down, transforming the great cabin into a private double cabin with ensuite access to the starboard head. This modular approach allows the owner to configure the interior for cruising solo, entertaining guests, or hosting extended family without structural modification. The dual heads feature matched glass-enclosed showers with molded seats, overhead hatches, and portlights. Dometic Vacu

What makes the MJM 50z a good choice for long-range cruising compared to other 50-foot yachts?
The MJM 50z is purpose-built for extended cruising with a 520-gallon fuel capacity that supports 35-knot cruising speeds, allowing owners to cover significant distances while maintaining efficiency. The design emphasizes natural ventilation through 16 opening ports and hatches, reducing reliance on air conditioning during passage-making. The convertible interior layout accommodates overnight guests without sacrificing the owner's comfort, and the abundant deck storage—including dedicated spaces for kayaks, bikes, and long-haul gear—makes it practical for multi-week voyages. The combination of triple Volvo IPS 600 engines, Seakeeper 9 stabilization, and Humphree trim tabs creates a stable, quiet platform that reduces fatigue during extended time underway, which is critical for cruising in varied sea states.
How does the triple Volvo IPS 600 propulsion system compare to traditional shaft drive on a 50-foot yacht?
The triple Volvo IPS 600 configuration delivers 1,305 total horsepower through individual 435 hp D6 diesel engines, each with its own pod drive. This arrangement provides superior fuel efficiency at cruise speeds—LOLA achieves whisper-quiet operation at 35 knots—while the pod design offers better maneuverability and directional control than conventional shaft systems. The IPS pods allow for joystick docking and Skyhook station-keeping, eliminating the need for traditional wheel steering and reducing operator fatigue in tight quarters. The redundancy of three independent engines also provides safety margins for extended offshore passages, as the yacht can continue operating on two engines if needed.
What is the practical benefit of Seakeeper stabilization on a 50-foot cruising yacht?
The Seakeeper 9 gyro stabilizer significantly reduces side-to-side roll motion, which is the primary motion that causes discomfort and fatigue for crew and guests underway. Unlike traditional stabilizer fins that require forward motion to function, the Seakeeper gyro works at any speed—including at anchor—making it valuable during extended cruising where the yacht may spend considerable time stationary. This system allows guests to move safely through the interior, sleep more comfortably, and reduces nausea during rough passages. For a 50-footer designed for family cruising and entertaining, the stabilizer transforms the onboard experience, particularly in the convertible guest cabin and salon where social activities occur.
How is the helm station designed to support long-range operation and visibility?
The MJM 50z helm features 360-degree visibility through push-button opening windshields and roll-up Strataglass enclosures, allowing the operator to maintain full situational awareness in all weather conditions while remaining protected. The Stidd helm seating is ergonomically designed for extended watch-standing, and the joystick control system reduces physical effort required for maneuvering, which is important during long passages. The Raymarine gS165 HybridTouch GPS plotter with integrated radar, fathometer, and AIS tracking provides comprehensive navigational capability, while the Volvo Penta autopilot with control head enables hands-free cruising. The wide side decks with stainless grab rails and side entry doors provide safe access to the foredeck without leaving the protected helm area, which is critical for single-handed or short-handed operation during extended voyages.
What interior layout options does the MJM 50z offer for different cruising scenarios?
The 50z features a flexible interior designed by Doug Zurn that adapts to various cruising needs. The forward stateroom provides a centerline island berth with ensuite access to dual heads and separate showers, serving as the owner's private retreat. The great cabin below the bridge deck functions as a social hub with convertible seating that can form twin or double berths, and the innovative cherry wall system slides into place to transform this space into a fully enclosed guest cabin with ensuite access to the starboard head. The galley integrates seamlessly into the great cabin with Corian countertops, a Vitrifrigo 2-drawer refrigerator, Isotherm freezer, and electric cooktop, allowing the galley to remain part of social spaces rather than isolated below deck. This configuration works equally well for owner-operator cruising with occasional guests or for entertaining larger groups at anchor, as the spaces can be reconfigured in minutes.
How does the deck layout support both safety and practical use during cruising?
The MJM 50z prioritizes walkable side decks with stainless grab rails, wide side entry doors, and a transom door to the swim platform, creating multiple safe access points throughout the vessel. The Esthec decking with biscuit tone and white seams provides superior slip resistance compared to traditional teak, reducing maintenance while improving safety in wet conditions. Dedicated deck lockers accommodate long-haul cruising gear, bikes, golf clubs, and water toys, while kayak racks mounted on the cabin top with handhold access allow owners to carry multiple kayaks without requiring davits or additional deck hardware. The Muir anchor windlass with Ultra anchor and stainless steel chain enables solo anchoring operations, and the custom stainless dive ladders with grab handles make water access convenient for swimming or water sports. The removable teak cockpit and pilothouse tables provide flexible entertaining spaces that can be stowed when underway, and the custom sunshades create a full enclosure of the sundeck, protecting occupants from sun and weather while maintaining visibility.
What mechanical systems support extended cruising away from shore infrastructure?
The Northern Lights 9kW genset provides independent electrical generation, allowing the yacht to operate all systems—including the 3-zone MarineAir 48,000 BTU HVAC, Victron inverter/chargers, and full AC/DC electrical panels—without relying on shore power or engine operation. The Glendinning 50A shore power reel with remote control enables convenient connection at marinas, while the Victron inverter/charger system manages power distribution and battery charging efficiently. The General Ecology Seagull IV water purifier ensures fresh water availability for extended passages, and the 150-gallon water capacity supports extended cruising when combined with water-making capability. The central vacuum system maintains cleanliness in confined spaces, and the dual Dometic Vacuflush heads with enclosed showers provide comfortable sanitation facilities that rival land-based standards. These integrated systems allow the yacht to operate independently for weeks at a time while maintaining comfort levels expected on modern cruising vessels.
How does the Raymarine electronics suite support navigation and safety for a 50-foot cruising yacht?
The Raymarine gS165 HybridTouch GPS plotter with Wi-Fi connectivity serves as the central navigation hub, integrating radar, fathometer, and AIS tracking into a single touchscreen interface. The Raymarine radar provides real-time weather and target tracking, critical for navigating in reduced visibility or detecting approaching weather systems. The AIS tracking system displays nearby vessel positions and course information, enhancing collision avoidance during coastal cruising or passage-making. The Raymarine VHF radio provides communication capability, while the Volvo Penta autopilot with control head enables precise course-keeping during extended passages, reducing operator fatigue. The Ritchie 4.5" SuperSport compass provides traditional magnetic reference independent of electronic systems, and the Kahlenberg horn with auto fog and anchor functions ensures audible signaling capability in all conditions. The 2x joystick docking stations with Skyhook station-keeping allow the operator to hold position in strong currents or wind without continuous throttle adjustment, which is invaluable for anchoring, mooring, or maneuvering in confined spaces.
What comfort features make the MJM 50z suitable for family cruising and entertaining guests?
The bright interior design maximizes natural light through 16 opening ports and hatches, creating an airy environment that reduces the enclosed feeling common on 50-foot yachts. The teak-and-holly sole with removable non-slip throw rugs combines traditional aesthetics with practical maintenance, while the cherry cabinetry and Ultraleather trim in the master cabin create a warm, inviting atmosphere. The dual heads with enclosed showers and molded seats provide private facilities for guests, eliminating conflicts during extended cruising. The convertible guest cabin option allows the great cabin to transform into a private sleeping space in minutes, giving guests genuine privacy rather than open-cabin sleeping arrangements. The galley's integration with the great cabin means meal preparation doesn't isolate the cook from social activities, and the dining/coffee table with adjustable pedestal accommodates both casual meals and formal entertaining. The 3-zone MarineAir HVAC system maintains comfortable temperatures throughout the vessel regardless of external conditions, and the Seakeeper stabilization ensures guests remain comfortable even in rough seas. The removable teak cockpit and pilothouse tables, combined with the custom sunshade enclosure, create protected outdoor entertaining spaces that extend the usable area beyond the enclosed cabin.
What makes the MJM 50z design distinctive compared to other center console or sportfish yachts in the 50-foot class?
The MJM 50z, designed by renowned naval architect Doug Zurn and built by Boston Boat Works, prioritizes owner operation and social cruising rather than fishing or charter functionality. The bridge deck layout places the helm forward with 360-degree visibility while maintaining an open, bright social space with settees port and starboard, distinguishing it from traditional center console or sportfish designs that prioritize cockpit space. The triple Volvo IPS 600 propulsion system with joystick control and Skyhook station-keeping enables effortless solo operation, allowing a single operator to dock, anchor, and maneuver without crew assistance. The Moonglow Silver Awlcraft 2000 topsides with Claret cove stripe and Esthec decking reflect a cruising yacht aesthetic rather than a fishing boat appearance. The convertible interior layout with a true forward stateroom, dual heads, and flexible guest cabin space prioritizes comfort and livability over fishing amenities like baitwells or fish boxes. The emphasis on natural ventilation, abundant storage for cruising gear, and integrated galley-to-great-cabin design creates a vessel optimized for extended family cruising and entertaining, making it suitable for owners who prioritize comfort and ease of operation over specialized fishing or commercial applications.
