Custom Line 120′


The distinctive shapes and spaces of the Custom Line 120′ embody consummate elegance and provide intense experiences that bring the wonders of the sea to life. Every detail reflects the personality of the owner. Solid yet lightweight, the hull of the 120′ is impeccably sleek thanks to the extensive use of carbon.

The vibrancy of the design finds its fullest expression in the generous glazing and floor-to-ceiling windows on deck, which draw the eye to the serene majesty of the azure sea. The light enlarges the spaces and opens up impressive views wherever you look. Dreams take shape in a personalised space where every detail is an aesthetic statement of impeccable elegance and taste.

In each of the 19 rooms, spread over 3 floors, the excellence of craftsmanship is palpable, the attention to detail. The advanced technology on board ensures a consummate luxury experience. From a dip in the Jacuzzi to surfing the 4G Wi-Fi internet, the Custom Line 120′ becomes a unique place where you can enjoy the sea from a truly exclusive perspective.
