Lighter, stronger and faster for better performance, handling and fuel efficiency without sacrificing cruising comforts or sea- kindliness... 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 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 new 50z, 40z, 36z, 34z and 29z  burn approximately half the fuel for boats their size while cruising at 25+ knots. This "Made in the USA" innovation allows the 150+ 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. They've left the door open for MJM Yachts to apply Formula One or America's Cup 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 370 hp Volvo Penta  D6 IPS 500s.  The 36z gets 2 nmpg at 25 knots with a pair of 220 HP Volvo Penta, 5-cylinder D3s... as does a  34z 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 and narrow beam with chine flats convert wave and wake into dampening 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, and less than 10' bridge clearance:  MJM designs are easier to maneuver around docks, fit in more slips, wait for fewer bridges and are readily trucked 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 summer-porch, fresh-air with fully-opening windshields and roll-up side curtains.  See more under PERFORMANCE above.

MJM 40z  - Solo Docking a Yacht is Now Easy & Safe 

We were frequently asked whether a larger MJM is on the design board.  Until now, we said, "No".  After studying recent larger 44-48 foot offerings from Hinckley, Grand Banks, East Bay, Hunt and Sabre we learned why these larger, heavier boats are no more functional or accommodating for extended cruising than the 40z. But, we did discover how the NEW 50z could be (see 50z).  40z seats 14 people in comfort on the same deck level plus 4 at a dinette below. So, bigger is not necessarily an advantage in terms of entertaining friends. 40z's top speed of 39 knots puts it in a world of its own... and she throws a lot less wake when trying to make time on the IntraCoastal! Belowdecks, there's a sense of openness and brightness with fewer walls and more overhead hatches and ports. Side access doors are uniquely hospitable and reduce dependence on dockhands. Handling the boat alone with Volvo-Penta IPS joystick and the DPS (Dynamic Positioning System) couldn't be easier. 40z's unique "fresh air" bridgedeck is more sociable for the driver and avoids long bridge waits of towering upper decks. The low center of gravity and propulsion system make handling a 40z in waves pure joy. 40z is one of a few vessels its size or type certified with ISO CE Mark's most seaworthy Class A Ocean rating. MJM has set a new standard in joinerwork and finish while giving up nothing in the design layout in terms of being able to sleep 6 when needed by converting dinette and bridgedeck into guest cabins...all with private access to a head and shower! On a 40z, bright sunny days can be devoted to boating...as there's no wood to varnish on deck. It takes 10 minutes to wash down. Care to guess how long it takes on a Grand Banks 47?  It's no wonder owners spend 2-3 times more hours on their 40z than on their previous boat.

36z offers the best of both worlds. It's fast, dry and fun to drive, responsive and predictable in waves and economical to run. Fully opening windshields and side curtains give you that invigorating wind-in-your-face feel on nice days. Yet, in the worst of weather, you shut the windows, roll down the side curtains and turn on the heat.  No need for the family to be hanging on for dear life and being buffeted by the elements on a center console or being confined to a dark, airless salon.  Six friends can sit in summer porch comfort under a hardtop in any weather...another six aft soaking up the rays or under a Bimini (not shown) shaded from the sun.  Below decks there's standing headroom with space and accommodations for a week's cruise. Side opening doors are hospitable to guests and make dock landings much less hazardous. Own the "smartest" boat of it size...2 miles per gallon when cruising and 4 gph for average use. Top speed is 35 knots from twin 5-cylinder 220 HP Volvo D3's. Anyone in the family can operate it's joystick docking system  – from a dock in only 17" of water, getting under 9.5 foot low bridges, or beaching her for a picnic.  36z is a unique design. Small enough to handle alone, yet big enough to entertain 10 on harbor cruises, dinner outings or watching the afternoon boat races.  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. With 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.  Click here for Passagemaker cover feature by Chris Caswell – "Labor of Love"- April 2011.***

MJM 29z DownEast - Day Boat & Weekender

With transom door, swim platform and single-level, convertible all-weather pilothouse, Stidd seats, the 29z Downeast model offers great versatility and comfort for fishing, swimming, day trips and family weekend cruises. It is the best looking and best sea boat of its size, which is 32' 6" LOA, 29' on deck. Professional captains who have driven just about everything afloat characterize the 29z as "sweet"... drier, more stable and more responsive to the helm in waves than anything they've driven.  Can you believe 3 nmpg at 25 knots with a single Volvo Penta 260 HP D4?  Because of MJM's leading edge epoxy construction, 29z is more fuel efficient than recently introduced diesel/electric hybrids. With 6 ft headroom belowdecks and enclosed head, the 29z has the space and functionality of a much larger boat. When a bow-thruster is combined with the agility of a sterndrive, maneuverability in tight quarters and shoal water operation is superb. You can take it to the beach or it can become it's own beach with high dive platform!

MJM 34z - The Perfect Performance Cruiser for Two

As a modern single-engine diesel cruiser with a conventional shaft drive, the 34z is unexcelled.  The primary design objective for the 34z, now numbering 64 afloat, was to create a good-looking, seaworthy, fast and functional cruising boat for two that could be operated by founder, Bob Johnstone's wife, Mary, solo. This meant "spacious enough for cruising comfort yet agile for easy handling". These normally conflicting goals mandated innovation in layout, hull shape and construction not found in traditional "Downeast" designs. Lighter, stronger and narrower was the answer, employing high tech epoxy construction techniques from racing sailboat and aircraft industries which were foreign to production powerboats. Once achieved, an unintended but very important benefit became fuel efficiency...burning 50% of comparably-sized boats.  Between 10 and 30 knots, the 34z (LOA including swim platform is 37' 5") averages 2.2 nmpg.  At harbor cruising speeds of 5 knots, it burns 1/2 gallon per hour getting 14 mpg (about the same as a Chevy Suburban) with a range of over 1600 miles.  Other key requirements were 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 and comparable to joystick docking systems.  There are many innovative features including tilt-forward Stidd seats to convert the pilothouse into a twin-berth guest stateroom, a removable Adirondack stern seat for those wanting to fish...and easy access through a transom door.
