World Leader in Fuel-Efficient Powerboats

Lighter, stronger and faster for better performance, handling and fuel efficiency without sacrificing cruising comforts or seakindliness... built with industry-leading epoxy composite construction in the USA: MJM Yachts are the most technologically advanced production powerboats of their type available. When it comes to a responsible boat purchase with optimum functionality, diversity of use and minimal long term investment risk, MJM Yachts go to the top of the class.  Click here for Soundings feature article - The Art of High-tech Powerboats- July 2010**.

MJM Yachts LLC was founded in 2002 by Bob Johnstone, who 25 years earlier had co-founded J Boats, Inc., the leading brand of performance sailboats worldwide with over 12,000 sailing. His focus on seaworthiness, performance and ease-of-handling carry over into MJM Yachts.  The 29z, 34z, 40z and new 36z (for 2011) burn approximately half the fuel for boats their size while cruising at 25+ knots. This "Made in the USA" innovation allows the 100+ owners of MJM Yachts to significantly lower their operating costs, while having a boat that's more fun to drive on a daily, spur-of-the-moment basis.  TWICE THE FUN, HALF THE FUEL has been MJM's mantra from the outset. Unlike automobiles, this goal can be achieved building boats without sacrificing style, comfort or performance. The answer lies in higher quality construction. Competing powerboat builders use dated, low cost and/or heavy fiberglass construction methods. This left the door open for MJM Yachts to apply Formula One racing car/custom racing sailboat technology to build stronger and lighter powerboats having less drag. Presto! The MJM 40z gets 1.2 nmpg at 30 knots with a pair of either 370 hp Volvo Penta  D6 IPS 500s or 350 hp Cummins AXIUS sterndrives.  A 34z attains nearly 2 nmpg cruising at 25 knots with a single 440 HP Yanmar diesel.  The 29z hits 31 knots with a single 4 cylinder 260 HP Volvo D4 diesel sterndrive, getting 3 nmpg at cruise speed. In car terms, owning an MJM yacht would be comparable to owning a 50 mpg Mercedes or BMW.

Highest Quality - Pre-Tested to "0" Defects

MJM Yachts licensee, Boston BoatWorks (BBW), is the one American boat builder, power or sail, having a 30 year track record using advanced materials such as epoxy, Kevlar, carbon and Corecell.  In their pursuit of excellence, BBW uses a proprietary wet epoxy pre-preg, vacuum-molding and oven post-cure method. Master Builder, Mark Lindsay has Olympic Medal, World Championship and America's Cup winning racing yachts to his credit because they're lighter, stronger and faster. In terms of long-lasting strength? MJM yachts are one of only a few vessels their size certified and built to ISO CE Mark Class A Ocean structural standards. All systems and finishes are "builder installs". Leaving nothing to chance, each MJM yacht is launched in Boston Harbor for sea trials before delivery. Tests of systems and calibration of instruments are conducted to insure "0" defects. This extra attention to detail costs more. Customer service, quality of construction, top-of-the-line hardware and performance are not compromised to meet a price. The MJM Yachts philosophy is that today's buyer won't be satisfied with anything less than the absolute best in terms of classic lines, available technology, functionality and performance. Such a strategy offers the best guarantee for daily enjoyment and long term investment value.

Stable, Dry Running, Offshore Planing Hulls

Apart from their stunning good looks, MJM Yachts take offshore performance to another level with Doug Zurn modified deep-V hulls.  This hull shape allows instant response to the helm without bow steer or bury in large waves... and keeps guests dry.  A low center of gravity dampens roll in a seaway. The narrower hull shape slices through waves instead of slamming.  By not having to lug around more engine weight and fuel tanks, by having shoal draft, 12' or less beam and less than 10' bridge clearance:  MJM designs are easier to maneuver around docks, fit in more slips and are readily trucked without penalty between seasonal homes. All MJM yachts comfortably seat at least 3 couples in the pilothouse, protected by a hard-top in all weather conditions... or in fresh air with fully-opening windshields and roll-up side curtains.  See more under the PERFORMANCE tab above.

MJM 40z- Extraordinary Offshore Performance

15 of these innovative new 40 foot yachts have been sold since introduction in January 2009.  Keys to this success are: Offshore capability as one of few vessels its size or type certified at ISO CE Mark's most seaworthy Class A Ocean rating; Quiet and dry running when cruising at speeds as high as 34 knots; Unique side-opening doors (P&S) for ease of boarding or hopping off onto a dock when landing; Mega-yacht-like single level entertaining deck and pilothouse that can seat 15 in comfort; Easy joystick maneuvering using computer-controlled twin Volvo-Penta IPS pod drives or Cummins Mercruiser AXIUS sterndrives; A very functional 6 berth layout with a large island berth stateroom, truly separate shower,  and two convertible guest cabins, counting main saloon and pilothouse; And, low maintenance costs as there is no uncovered wood on deck.

 
 
NEW MJM 36z - Entertain Friends with Joystick Control

36z-powerboat-fuel-efficient-green-eco-friendly yacht

The NEW 36z is the most gracious and versatile design under 40 feet one can imagine… easy to own and to use daily just about anywhere – from your dock in only 17" of water, getting under 9.5 foot low bridges, or beaching her for a picnic. Note the side-opening doors to welcome guests and for ease of handling docklines. 36z is a nice size. Small enough to handle alone, yet big enough to entertain 10 on harbor cruises, dinner outings or watching the afternoon boat races. A Volvo-Penta IPS-type joystick controls twin 5 cylinder, low-emission D3 diesel engines with OceanX sterndrives, having underwater exhausts. Speeds to 30 knots are luxury car (Volvo XC-70) quiet. Docking with the joystick is easier than parking your car. Being at one with the boat, surfing down waves at 25 knots with the responsive destroyer wheel is a thrill not to be missed. The 36z can go just about anywhere and deal with most obstacles. Thanks to hydraulic relief valves, sterndrives tilt up when their skeg strikes an underwater object, then bounce back down again to keep on running. When tilted up, the props are reachable from the swim platform without going swimming. 36z will stay looking new and beautiful for many years.  There's no wood on deck to maintain.

MJM 34z - The Perfect Performance Cruiser for Two

34z-green-fuel-efficient-ec-friendly-power-boat-yacht

The primary design objective for the 34z, the company's first boat now numbering 64 afloat, was to create a seaworthy, fast cruising boat for two that either the founder or his wife could operate alone with no one else aboard.  The boat had to be "spacious enough for cruising comfort yet agile for easy handling". These normally conflicting goals mandated innovation in both design and construction: lighter and stronger. A major end benefit became extraordinary fuel efficiency. To honor that inspiration, the unofficial meaning of the corporate acronym "MJM" became "Mary Johnstone's Motorboat.  Also important was comfortable seating, visibility and ventilation for three couples underway in an all-weather pilothouse.  Bow and stern thrusters with a single throttle/shift make the 34z easier to park than a car.  There are many innovative features including tilt-forward Stidd seats to convert the pilothouse into a twin-berth guest stateroom, made private when lining all the windows with privacy curtains.

MJM 29z - The Ultimate Sea-Going Weekender

29z-green-fuel-efficient-eco-friendly-power-boat

The 29z has hospitable, living-room-like, wrap-around seating for 10 in a single-level cockpit and pilothouse.  At the same time it is the best looking and best sea boat of its size.  Those who have driven just about everything afloat say the 29z is "sweet"... drier, more stable and more responsive to the helm in waves than classic 50 year old deep-V Hunt designs, while being comparable in terms of re-entry wave impact. Can you believe 3 nmpg at 25 knots with a 4 cylinder 260 HP diesel and top speed over 30 knots? With 6 ft headroom belowdecks, an enclosed head and engines aft under the stern seat, the 29z has the all-weather living space and functionality of much larger boats like the Hinckley 38 TR... at only a fraction of the investment or operating cost.  When the bow-thruster is combined with the agility of a sterndrive, maneuverability in tight quarters is superb.
