Doug Zurn’s unique modified deep-V planing hull has a slippery 3.5:1 length to waterline beam ratio vs. a
more typical bluff 2.7-3.0 to 1. Combine that with Boston BoatWorks’ lighter and stronger epoxy
composite construction and you have the secret of MJM’s undisputed best-in-class efficiency and
performance. In 2007, MJM put its unique structure to the test in its twin outboard MJM 29z. The boat
proved the Hull design/epoxy construct to be a success: the MJM 29z actually gained stability at high 50
mph speeds in stark contrast to the chine-walking traits of some leading outboard brands. So, MJM was
very well positioned in model year 2018 to introduce its new line of outboard express cruisers, starting
with the 35z and 43z and the 53z in model year 2020.
Yes, weight matters and hull design matters when it comes to both speed and fuel efficiency, MJM comes
out ahead on both components of performance. To make the point: an MJM 43z with triple-Verado
outboards matches the IPS diesel powered Sabre 45 on fuel efficiency. The jet’s not even close. Then the
43z eclipses both on range. At top speed, with less horsepower, the MJM 43z is 42% faster than the
For Fuel efficiency, the hands-down winner is the MJM 40z with Volvo Penta IPS 500 inboard diesel
power at 1.2 NMPG. With nearly 100 devoted owners singing her praises, the MJM 40z is arguably the
best all-round inboard diesel boat on the market. Easy to use at the drop of a hat, comfortable enough to
live on for the summer or a Great Loop adventure, the 40z is one of only two boats of her size in the world
(a Nordhavn 40 is the other) that’s ISO Certified Category A Ocean for stability. A Seakeeper gyro is icing
on the cake. For all these reasons, it’s nearly impossible to to find one on the brokerage market!
With the 40z and 43z, MJM offers the best of both inboard and outboard worlds. Surprisingly, when it
comes to annual operating costs, there’s not much difference. Granted, outboards burn more fuel. But,
the annual maintenance costs of an inboard IPS diesel are nearly 2x. yet still not as pricey as jets. The
method of propulsion is your choice. Creating the best performing inboard and outboard express cruisers
for your boating enjoyment has been ours.
