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.
