2020 MJM Yachts 40z

Boston, Massachusetts


Clare Ann is a 2020 MJM 40z, hull #105, delivered in July 2019. She was motored from Boston to Camden, ME, where she has spent the summers at a slip in Camden Harbor, cruising Penobscot Bay and wintering indoors. She is now at Boston BoatWorks for the winter.

With slightly more than 200 hours on her engines, she is virtually a new boat. The same boat (renamed a 43zi because swim platforms are now included in the overall length) currently sells for over $1.5M. 

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 other is the Nordhavn 40—no longer made). 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. The joystick controlled, twin IPS Volvo Penta drives make any skipper look good when docking and the DPS station keeping function provides a cool 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; large sliding glass side windows; power-operated front windshield; Humphree Active Ride Control and Seakeeper Gyrostabilizer contribute to the ease, comfort and performance of this fine boat.
