Sanlorenzo SP 110

Superyacht 75 – Autumn 2022

Sanlorenzo joins the open coupé world with this new proposal, which innovates liveability and keeps a keen eye on sustainability. A cutting edge project, which makes the history of yachting by combining high performances, unusual room onboard and respect for the environment, thanks to deep research and technological development.

It had been longtime in the air. When Massimo Perotti summoned his press conference in 2018, at Düsseldorf boot, held by Pershings’ and Widers’ father Tilli Antonelli, the idea was to unveil electric diesel and hybrid projects. And the question was: “Ok, electric, but any Open?” After three-year research, what Sanlorenzo need for a new product in their own style, and one to build her, here we are with SP 110: a new, shocking, unprecedented product, displaying best technology and perfect sustainability. SP stands for Smart Performance. Smartness everywhere, in design, layout, hull. And details, of course.

A five-specialist team was set up for the result: Tilli Antonelli for general conception, Bernardo and Marina Zuccon for design and layout, Piero Lissoni for décor, high speed magician Marco Arnaboldi for hull and propulsion. The team was Perotti’s winning weapon to launch the nth successful product, bound to join the best Oscar prizes in nautical industry.

A sporty cut is found for the first time on a Sanlorenzo boat, which doesn’t go with losing the brand’s fil rouge. “it was hard job to create a new style” says Bernardo Zuccon “we drew back on the yard’s history on the one hand, on the other one we designed a new recognizable identity to naturally combine new design processes with a familiar conception of range and products”.

The Studio cooperated with Tilli Antonelli, whose name made history in boating, nowadays Sanlorenzo product and development manager. The other natural connection was with architect Piero Lissoni, the yard art director. “SP 110 tries to challenge the typical canons of high-performance boats, some of them at least. Still respecting their historically characteristic features, such as aerodynamic and organic surfaces.

And the compromise was found, with Tilli Antonelli: a boat where dynamism interacts with liveability, essential in this kind of boats the former, higher than thought on them, the latter”, adds Bernardo Zuccon. As imposed by the yard’s philosophy rather than commercial strategy, the boat appears simple and minimal, in many of her aspects. The hidden air vents for instance, stylistically following the glass bend. Or the disappearing anchor, with its ingenious system for expulsion and retraction, both solutions suggested by Marco Arnaboldi skillfully integrated within the design by Bernardo Zuccon. Zucconi penned an equally stunning internal layout, which somehow recalls Bluegame’s latest proposals, Sanlorenzo’s renowned property.

The living area stretches on two different levels, using the lower deck aft area. “A strong relationship between inner and outer space is felt onboard”, says Martina Zuccon, “the fundamental synergy between guests inside and outside was our basis to create a hermetic shell easily opened for space relationships. The terrace descends to water, and all technical information to lower ladder and walkway are hidden, nothing is seen.

The boat was modelled on this balance between motion and stillness: this element is hermetic while moving, it is closed and compact. Aero and Hydrodynamic performances are the core of the project, yet everything opens up when the boat is at anchor. A door opens from the cockpit to generate the ladder leading to the beach, to descend to the sea. And the cockpit itself is differently set up to become an extremely enjoyable area”. The cockpit, again, is the central point for the boat’s liveability.

The dining area can be separated from the kitchen, wall on the left, both with a solid or a see-through closure, which open the view on the bridge. Next page, the bridge. Electronics onboard have -apparently- reduced it to two large screens to control everything. The reversed windscreen, Bluegame style, makes the room look much bigger.

The five metre-distance between the gunwales, its lowered position to make the guest even close to water, the direct access to the living room through a completely opened glass door, make this area absolutely unique on a boat of this category. Featuring a very flexible lounge area, it easily adapts to different moments of life onboard. A tender can be laid beneath the walkway, which clearly disappears when not needed thanks to a beam-oriented invisible crane; this allows total fruition of the space, down to the sea level.

The kitchen is another highlight onboard, on the main deck between the living room and the bridge; it can be closed by thick or translucid walls, the latter allowing to visually reach the bridge through the glass, offering a space widening perspective. The luxury minimalism Piero Lissoni is excellent at creating characterizes furniture, perfectly embracing the project general philosophy. The challenge was to keep a refined elegance without indulging on details, sticking to a substantially essential finishing.

The same approach was kept for the interiors,, lighter materials were used especially in toilets, where a lava-like stone was used instead of marble. “I tried to bring the other models print to this sporty one, said Lissoni, open spaces, interior-exterio connection, and high technology. One of the crucial elements is the double layer aft, which makes the main deck talk to the lounge on the lower one, through a hyper-technological staircase”. The hull was a fundamental step in SL 110 creation.

It was designed by Marco Arnaboldi, then optimized to waterjet propulsion. The latter brings considerable advantages compared with traditional propeller propulsion, being less affected by the boat weight variations and therefore more flexible. Studying water lines allowed for a surprisingly efficient hull, over 8 metres wide and 33 long in total. The doube edge flank reduces width at waterline to increase performances and comfort even in rough sea, as well as a major volume to use upwards.

Several solutions were also devised to reduce weight, and therefore enhance sustainability, performance and consumption. Lighter materials for instance, like stratified glass for the wide glass surfaces, covering nearly 80% of the boat. Glass resumes the hull tint outside, to make the whole surface homogeneous, while remaining bright and lit inside. “The entire hull and the deck are built in hybrid carbon-composite sandwich, explains Arnaboldi, to reduce weight without diminishing resistance; I have widely used this kind of technology and techniques all over my career. Sustainability and fuel saving have been so much dealt with lately.

the mid ship master cabin, with its prow oriented restroom, which also provides a noise reduction element between the suite and the crew area. The ceiling dark slats and the light ones close to the bed are Piero Lissoni’s signature, who uses them to visually enlarge volumes or pieces of furniture.

The smaller weight ensured by lighter and finely manufactured material abruptly decrease CO2 consumption per mile, such a frequently heard topic”. SP110 is equipped with am energy recycling system, based on 6KW mono-crystal high efficiency solar panels and a set of lithium batteries to keep hotel functions onboard active without using generators.

The deckhouse design has been studied to make room for the panels without altering the boat’s aesthetic balance. Three V12-2000 Man are found in the engine room; 12 90° V-cylinders for 2000hp, only weighing 2380kg each, for a perfect 1,62 kg/kw ratio. They are clearly coupled with two MJP 550 CSU side waterjets, directable and completed by a 550 central booster.

This power, along with the hull, reduced weight and waterjet propulsion, easily allows SP 110 to reach 40-knot maximum speed. Considering that each engine consumes 280 liters at 30-32 knots (75% of its power), 12000 liters ensure a 400nm range. Three-engine propulsion system proves economical as it allows to only use two, without the central booster, for normal sailing.
