Casta Diva Boat | 50' MJM 2017

The MJM 50z is one of the most versatile boats ever built, offering speed, low maintenance and ease of use for dayboating and harbor cruising, while the generous accommodations, efficiency and seaworthiness make for an ideal long-range cruiser. There is no such thing as the perfect boat, but the 50z is about as close as you can get. The MJM has excellent design and build quality without heavy annual maintenance costs seen on similar boats.

Casta Diva is a well maintained, single-owner boat with summer use in New England and only a few winters down in Florida and the Bahamas. She is likely the best equipped MJM for long distance off-grid cruising with the 2 cabin/2 head layout, extended galley, separate washer and dryer, watermaker and dinghy setup.

Highlights include:

ISO certified Category A Ocean
Triple Volvo IPS 600s - 340nm range at 34 knots and 450nm range at 27 knots!
Zero exterior teak = easy and less expensive to maintain
Custom tender chocks and davit on the hardtop
Spectra Catalina watermaker
Rich full cherry interior
One of the few 50z's with 2 cabins and 2 heads
