The new semi-displacement SD90 by Sanlorenzo is a further confirmation of a process of continual evolution, one that brings together very advanced technological performance with true craftsman quality. All of the boats made by the yard are true to the brand’s look and are an expression of its quest for sustainable solutions and drive to always bring new ideas on board. The first impression you get when looking at the SD90 up close is that of a very elegant boat, with pleasing and cleverly balanced exterior lines, designed by the Zuccon International Project studio.

The lounge on the main deck features very delicate colours and gives centre stage to the sofa and Sengu table, made by Cassina, the Ruff armchair by Moroso, the custom-made adjustable table and the recycled bioglass back.

In her entirety, the SD90 comes across as a very compact and homogenous yacht, in part thanks to the use of One-way glass, which means the windows are the same colour as the hull and blend in with it. The SD90 is nearly 28 metres long overall and is laid out over two and a half decks.

 The master suite, made up of a walk-in wardrobe, sleeping area and bathroom, is split over two levels and is much more spacious than traditional layouts.

The hull, designed in association with Philippe Briand, has been optimised to limit resistance, making it even more efficient. Just as it was with the SD96 and SD118, the interiors were designed by Patricia Urquiola, able to bring aboard her particular viewpoint and an approach that is guided by convertibility. It is a very interesting concept, especially on a yacht where – by definition – owners and guests like to spend a lot of time, and the possibility of having flexible interiors enables the boat to adapt to demands that are always new and different while underway and during stays on board.

«Having designed the first two boats in the SD line, I loved the fact that they are going back to a smaller size instead of something larger. With each model, we worked to turn the spaces around, in close contact with both the engineers and also the people who handle the windows and design the hull. The design is very complex; it contains extremely technological elements alongside traditional craftsmanship».
Patricia Urquiola

The interior design creates a refined and gentile atmosphere, with continual references to the marine world and a careful choice of sustainable materials. The woodwork on the lower deck, for example, has been finished by Paper Factor in recycled paper made from FSC-certified crops; the wall forward of the main deck lounge, which is also the backdrop to the room, has been made in recycled bioglass and was developed to be a translucent filter that allows a glimpse of the staircase behind it, which gives a greater feeling of space. The ceiling is in Will, a product by Cimento made from sustainable cement in strips of just 3 millimetres.

A characteristic element of the SD90 is the flooring made with an interwoven continuous pattern which links all of the spaces of the boat, inside and out.

«There is an important legacy to bear in mind, without ever losing sight of two essential issues: the volumetric balance of the distinctive features, which help to harmonise the proportions, and the respect for the brand’s image, one that is so vital, solid and has such strong roots».
Martina Zuccon

Attention to sustainability extends as far as the smallest details: for example, the textiles and rubber of the sofas and the Cassina armchairs are made from recycled material; the curtains are in recycled PET from Dedar, while the Warli carpets are made from a natural linen fibre. The lounge features some pieces designed by Patricia Urquiola, such as the sofa and the Sengu table produced by Cassina, and the Ruff armchair by Moroso; the overall feel is perfectly balanced, including the customised table, featuring extendible legs in oak and a bronze-plated metal sliding top which means the area can be used for dining, or as a living room.

«The world of “Navetta” yachts is a fascinating one and is as romantic as it is complex, because it is associated with people who choose to live at sea for a considerable amount of time, for whom time is not a limitation but a luxury, and as consequence need spaces and opportunities that are often greater than those of boats of the same size but are of a different type».
Bernardo Zuccon

The choice of colours is always very delicate, as is the illumination which uses a system of downlights on a rail, a design that is elegant and not at all invasive. The ceiling, which is embellished with a micro pattern reminiscent of the netting of crab pots, creates some interesting and interesting reflections from the sea. Still, on the main deck, the owner’s area in the bow is made up of a walk-in cupboard, a cabin area and a bathroom, and spreads across two levels creating much more room than a traditional layout.

The bronzed band, the ceiling and ribbed oak panelling create a stylistic continuity with the other rooms. The bathroom boasts distinctive washbasins and vanity tables in terrazzo green Agglotech with natural aggregates made from recycled marble, while the ribbed front finish works well with the rest of the area. The idea of convertibility is also present on the lower deck of the SD90; the space in front of the staircase is a lounge area that, when required, can be closed and become a private cabin in which the sofa is converted into a bed. All of the solutions have been researched to ensure the boat is as liveable as possible and to make guests feel that they are immersed in a warm and welcoming environment.


A distinctive feature of the SD90 is the flooring: a continuous interwoven pattern flows through the entire boat, both inside and out, making the various areas feel fully connected. This approach is reinforced by the large openings, with windows that link the lounge with the cockpit area. The external area in the bow also features a high degree of convertibility: the panel in the bow area can be positioned so that it follows on from the group of sofas to cover up the anchoring equipment, or it can slide down and run under the sofa area when the crew need access.

The hull, designed in association with Philippe Briand, has been optimised to limit resistance, making it even more efficient.

On the flybridge, the convertible table with a Cimento base means the area can change from a lounge into a dining room. Great attention has been paid to the use of sustainable materials in outdoor furnishing as well, both for fabric covering the sofas and seats, and the furniture tops, made in Gees, a type of recycled fibreglass.
