1985 Santamargherita Motor Yacht “SISISI”

SISISI’s exterior design is defined by her iconic canoe stern and large fantail aft deck, providing expansive outdoor living space ideal for relaxed cruising and entertaining. A spacious sundeck offers additional lounging and social areas, while her open flybridge layout enhances visibility and onboard enjoyment. Her classic profile and traditional proportions give her a distinctive presence rarely seen in modern yachts.

Powered by twin Gardner diesel engines, recently professionally overhauled, SISISI is renowned for her efficiency, consuming approximately 1.5 gallons per mile and offering impressive long-range capability with large fuel capacity. Her engineering systems have been continuously maintained and upgraded, including rebuilt transmissions, electrical systems, and structural upkeep.

Her interior features warm walnut burl finishes throughout, reflecting classic yacht craftsmanship and traditional elegance. She accommodates eight guests in a flexible four-cabin layout, including two master cabins, offering a rare level of comfort and privacy for a yacht of her era. The interior spaces are well proportioned, combining character and practicality, and have been carefully preserved through decades of attentive ownership.
