Creating your perfect yacht is a journey we’ll make together

On the outside, the dark streamlined windows have remained the same for over 60 years. There is no need to read the name: even from a distance, a Sanlorenzo yacht is immediately recognisable, at first glance.

Streamlined, elegant and well-balanced at the same time: this is the SL fleet, the planing yachts by Sanlorenzo, which in 1985 marked the beginning of the production in plain fiberglass at the shipyard. Boats for owners who choose performance as a seagoing philosophy, fending the waves with complete stability and safety, with total quality of navigation that combines performance and comfort.

On the inside your imagination is your only limitation. Design and commission your very own version of this SL78 tailored to your specific tastes and requirements.

An ample lounge area at the bow in the shade of an awning, and a flying bridge larger than what you would expect to find on a 24-meter yacht: this is the outer image of the SL78. The interiors, completely personalised like all Sanlorenzo boats, have a contemporary, essential character in this model, based on tones of cream, beige and grey, which return in the finishes of the floors, walls and ceilings of all the spaces. The special custom solutions include the staircase leading from the living area to the upper deck: each step is enclosed by two panes of glass, and seem to float in the space. The cabins, all with private bathrooms, large windows and games of mirrors amplify the natural lighting. But light is (also and above all) a leitmotif of the design: in the SL78 the bulwark, recessed in the saloon area, considerably increases the brightness. With the result of blurring the boundaries between inside and outside.



One look at the exteriors of this yacht conveys an idea of how the SL78 can offer owners everything they need for remarkable comfort in close contact with the sea. On the flying bridge, at the stern, a shaded dining area is flanked by a spacious sunbathing area; the bow on the main deck is outfitted with cushions for carefree basking in the breeze. The sense of assured comfort continues inside, where the dominant tone is the same cream color used for the outdoor furnishings. The lacquered walls and ceiling form a contrast with the furnishings in an eclectic, refined composition featuring contemporary design pieces like the sofa in antique rose velvet, and a dining table made with recycled wooden boards. The living area is divided from the galley by a mirror panel with brass inserts, shifting into the mood of the cabins: the same reflecting finish (this time backpainted in teal green) segues to the paneling of the bed in capitonné leather. All rigorously custom designed, down to the smallest details.
