Her interior reflects a contemporary Italian style, furnished with pieces from Minotti and Paola Lenti and finished in grey oak, Nuvola Canapa leather, and Calacatta marble, with curved joinery softening the transitions between spaces. A VIP cabin with an island bed sits belowdecks alongside two twin cabins, one fitted with an additional Pullman berth. The main salon opens directly to a formal dining area, with a galley equipped by Boffi close at hand.

Teak decking runs across MUMA's exterior areas. Her flybridge carries a hardtop, a dining table, and lounge seating, creating a shaded gathering space above the main deck, while a stern cockpit and a bow seating area extend usable outdoor space fore and aft.

Twin MTU 16V 2000 M84 diesel engines give MUMA a top speed of 28 knots and a cruising speed of 18 knots. Her fiberglass hull and superstructure form a planing profile, and electric fin stabilizers with a zero-speed function keep her steady at anchor as well as underway.

At 155 gross tons, MUMA carries strong volume for her size, giving her four-cabin layout added scale without extending her overall footprint.
