New Boat: Sanlorenzo SP110

The first in a new line from this Italian shipyard, with three engines and an emphasis on performance and efficiency—and spectacular design.

Eyebrows went up when Sanlorenzo boss Max Perotti announced that he had brought Tilli Antonelli on board. For an essentially conservative shipyard that prides itself on the elegance and quality of its yachts, it was hard to imagine what sort of contribution they could expect from the founder of Pershing—a shipyard that also prides itself on quality and elegance, but is ultimately all about high speed and handling.

And sure enough, it’s hardly a surprise to discover that Tilli’s initial thought for the SP110, Sanlorenzo’s first coupé design, was triple 2400s and 50 knots. “But we decided that wasn’t very Sanlorenzo,” he smiles.

The ‘SP’ stands for ‘smart performance’ and the thinking is that with a ‘fractional’ triple jet-drive installation you can run symmetrically on one, two or all three engines, to optimize the yacht’s performance and efficiency in any set of circumstances. According to Tilli, the most economical way to cruise in the 110 is at ten knots on the outer pair of engines—although, if you insist, running on just the fixed-drive center engine gives seven knots, and you can steer the boat using the Humphree interceptors.

The hull design has been optimized for fuel efficiency, two chine steps reducing its substantial 27-foot beam to 21 foot 4 inch at the waterline, to lower drag and enhance seakeeping. The bow sections present a remarkably incisive entry, while deadrise lessens as it runs aft to a pretty deep-V 16.4 degrees.

Augmenting the intelligence of its smart naval architecture, the structure of the 110 incorporates lightweight materials, while Sanlorenzo also worked with RINA, the Italian classification society, to adapt its window glass specification to allow the use of a thinner laminate. That led to a weight savings of ten percent, according to Tilli, which is not insignificant on a total glass weight of some four tons.

But let’s get real. This is still a 40-knot, hundred-ton, hundred-footer packing 6,000 horsepower. “At maximum she burns 294 gallons per hour,” says Tilli. “But at a sensible cruising speed, say 31- to 32-knots in calm conditions, the consumption drops to 233 gallons per hour.”

If you’re wondering what’s sensible about that, and thinking that maybe this is not the boat for you, hold on just a minute. Nothing about the SP110’s naval architecture, propulsion, performance or engineering can hold a candle to the sheer chutzpah of its design. The exterior forms, by Zuccon, are deceptively simple. The profile shows just a hull with a deckhouse on top. But somehow, the three-dimensional reality of the 110 made it a true head-turner on its launch at the Cannes boat show, and one of the coolest boats on display.

The interior layout, courtesy of Milan architecture studio Lissoni & Partners, is a veritable tour de force. It is reminiscent of the same designers’ work for Sanlorenzo’s Bluegame brand, although according to Tilli development of the SP110 began earlier, so his baby deserves the credit. The open aft deck is broad, flat and unencumbered—the tender hoist is a U-shaped gantry that disappears completely beneath the teak—and from there you can either head down to the low-level private aft salon, or up to the raised main salon above. Both are open, so there is no impediment to the view aft. And from the aft deck seating you can still feel that you are in nominal touch with everyone inside, whichever level they happen to be on.

It is a very clever piece of design—the balustrade gives the upper saloon the feel of a balcony, and is quite unlike anything I’ve ever seen on a yacht before—because it not only looks absolutely stunning, it’s also practical and sociable.

The remainder of the interior spaces are slightly more conventional. The galley lies athwartships, forward of the main salon, and leads on to a separate wheelhouse with deck access both sides. There is also a small foldaway helm station up on the roof, which is fun, and the foredeck seating area is a generous expanse.

As configured on this first example, the SP110’s lower deck layout provides a matching pair of well-proportioned VIP cabins amidships, each side of a central corridor, and a pair of additional cabins just forward. It’s always useful to have four cabins, but to complicate matters this area can be fitted out instead as a large full-beam master suite, should you so wish. Which could be spectacular.

But don’t sweat the small stuff. The SP110 is spectacular anyway.
