2018 MJM Yachts 40z


Fins is a 2018 MJM 40z, hull #81, delivered in March 2018. She was transported from North Point Yacht Sales, Annapolis, MD to Savannah, GA, where she has resided at a private dock at Spring Island, SC, cruising Port Royal Sound area as far north as Charleston.


With slightly more than 260 hours on her engines, she is virtually a new boat. The MJM 40 foot current boat offering (named 4z featuring open bow day boat design) is expected to sell for over $1.7 Million when production begins.


The 40z is often recognized as the best forty-foot performance cruiser afloat. She is one of only two 40’ yachts ISO Certified Category A Ocean. The classic modified deep-V Doug Zurn hull provides a smooth, dry and stable ride. She cruises at 32 knots and is capable of 38 knots. The dual lifting strakes, chine flats, and 19-degree transom deadrise provide unmatched stability, level acceleration and a dry ride. Thanks to strong, lightweight heat-cured, epoxy with E-glass construction, her fuel efficiency is as much as 50% better than conventional yachts. The joystick controlled, twin IPS Volvo Penta drives make docking easy and the DPS station keeping function provides a way to pause for lunch without deploying the anchor.


The panoramic sightlines, open galley with dinette, pilot house and cockpit on the same level, side boarding doors at floating dock level, strataglas side windows, power-operated front windshields combined with Seakeeper Gyrostabilizer contribute to the ease, comfort and performance of this classic yacht.


The MJM 40Z Model is no longer in production effective 2022 and is not anticipated to be built again in this layout

Steering System
Joystick Control
Manufacturer Provided Description

The primary design goal for the 40z was to create a 40 foot powerboat that would handle like a 30-footer at idle speeds in tricky docking situations. The Volvo-Penta IPS joystick control technology makes this goal a reality. The IPS system works with twin pod drives under the hull. When conventional twin-engine controls are in neutral, a single joystick takes over with fingertip control. There are no thrusters. Through a unique computer program, each drive unit is independently operated in terms of direction, rpm and forward-reverse gear. This system works far more intuitively than conventional twin shaft drives or joystick/thruster operated jet drives.

Unique Features
-Side-opening doors (P&S) overcome a common problem, getting aboard or getting off when handling docklines.

- Single-level seating for as many as 15 at cocktail time or for a family picnic

- Roll-up side/aft curtains and fully-opening windshields to regulate airflow in the pilothouse to suit conditions.

- Large (60x78) island berth and separate shower in owner stateroom.

- Two convertible guest cabins, one with dinette option.

- 40z can be trucked overland without penalty. Width doesn’t exceed 12 feet and height on a trailer is less than 13.5 feet.
