MJM – 40z Downeast

Maryland, United States

The 40z may very well be the best performance-oriented cruising boat ever designed. 

Few boats so precisely meet their intended goals.  The 40z marries performance with fuel efficiency, extended couple cruising with trend setting day boat sociability, safety and ease of movement with a single level deck and two steps to the cabin.  Volvo IPS joystick technology eliminates stress by making maneuvering around docks is easy and safe.  Easy transport to your favorite destinations, a 40z can be trucked overland without penalty. Width doesn’t exceed 12 feet and height on a trailer is less than 13.5 feet.

Delilah, #17, is a beautiful example of an upgraded and updated Express style 40z.  Her owner has spared no expense in her upkeep and maintenance.  She is loaded with options and upgrades including SeaKeeper, New Raymarine electronics, Paint,and softgoods.  

If you’re looking for a boat that is and 100% ready to take you on your next adventure, Delilah is a must see.

Beginning forward, the MJM 40Z has a generous master stateroom with large(60" X 78") island berth and generous storage in 4 drawers in the aft end and large plastic storage bins underneath. Dual bookcases and wide shelves are handy to both sides of the berth. There are two 19 X 19 hatches overhead, one of which is directly over the berth for watching stars at night or quick deck access which is a safe and dry way to inspect the anchoring gear without having to go on deck. These hatches plus in hull ports provide exceptional light and ventilation and are equipped with shades and screens. There's an ensuite shower with seat to starboard as well as a combination head/shower to port.

Just aft is the convenient and fully equipped galley to port and a convertible dinette to starboard.  It's a wonderful area which is well suited to dining, playing games, working or just keeping the cook company.

The pilot house is an expansive area with comfortable seating for eight with the wide Stidd chairs that rotate to join the conversation and two comfortable settees with a teak table for alfresco dining and cocktails.

Continuing aft is the expansive cockpit which increases the seating capacity on a single level social area to 15!  With all the Strata Glass rolled up and the bimini deployed, the open-air covered space is expansive.  

The storage is enormous with a central hatch to a utility room under the pilot house plus two cavernous lockers that will swallow up a couple of mountain bikes each under the settees.

Hull and Deck

The Doug Zurn designed 40Z hull features a modified deep - V planning hull with 19-degree deadrise aft running forward 13 feet which then transitions to 50 degrees forward. This combined with dual lifting strakes, chine flats and generous bow flare make for the driest ride, exceptional stability and tracking upwind or down, and a low vertical center of gravity so she'll carve into turns rather than lean outwards as low-tech heavier boats frequently do.

The legendary MJM fuel efficiency (as little as 50% of comparable 40 footers) is achieved through her high-tech build that eliminates fuel wasting excess weight. Yet this high tech, high strength, high quality build process is certified ISO CE Mark Class A Ocean.

The ergonomics are simply unmatched starting with the innovative side boarding cockpit doors. The single level cockpit and pilot house sole and abundant handholds make moving about easy.

The mjm 40z is built with advanced composites using vacuum bagged lightweight wet pre-preg, post-cure, Epoxy/Kevlar/Eglass/Corecell creating an exceedingly strong hull with a low center of gravity which provides greater stability and seaworthiness as well as an impressive comfortable ride.  She is one of only two 40’ yachts ISO Certified CE Mark Category A Ocean.
