The Sanlorenzo SL120A: Asymmetry at Flagship Scale

The signature
The SL is the line Sanlorenzo calls its own monogram — over forty years of flybridge planing yachts, and the range where the yard's asymmetric idea was born and refined. If you want the width of a considerably longer boat without paying for the length, this is where to look.
The asymmetric concept is simple to describe and hard to execute. Conceal or reroute the circulation down one side of the boat, and the width you would have spent on a walkway comes back as interior volume and a much better connection to the water. Sanlorenzo's own defence of it is the honest one: asymmetry is not just aesthetic — it makes the interior space feel larger.
Sanlorenzo's fleet page lists six SL models: the SL80A, SL86A, SL90A, SL96A, SL110A and SL120A. We have reviewed five of them, from 87 to 121 feet.

Pioneering asymmetric design at 87'3": concealed circulation buys back interior volume, and twin MAN 12V 2,000s give a published 29 knots — the quickest SL here.
Asymmetry in the middle of the SL range: twin MAN 12Vs at 2,000 HP each for a published 29 knots, 2,378 gallons of fuel, eight guests and three crew on 90'7".
Asymmetry hidden behind conventional lines — concealed gangways and opening terraces on a 95'2" hull, with twin MTU 16V2000 M86s for a published 28 knots.
Sanlorenzo's most refined asymmetric layout at 109'11", offered with MTU M96 or M96L power for a published 26 or 27 knots, carrying ten guests and five crew.
The largest asymmetric SL: 121'1", twin MTU M96Ls for a published 27 knots, ten guests and six crew.

Moving Up the SL Series
SL86A — 87'3", 29 knots, 8 guests / 4 crew. Twin MAN 12V 2,000s. The point where the asymmetric idea becomes accessible.
SL90A — 90'7", 29 knots, 8 guests / 3 crew. Twin MAN 12V 2,000s again — the same power on three more feet of hull, and the same published 29 knots. 9,000 litres of fuel on a 21'4" beam, and a crew count of three: one fewer than the SL86A carries. Sanlorenzo's own line for it is "mastering the experience of asymmetry".
SL96A — 95'2", 28 knots, 8 guests / 4 crew. Twin MTU 16V2000 M86s. The version that hides the asymmetry behind entirely conventional exterior lines.
SL110A — 109'11", 10 guests / 5 crew. Two MTU options with a published speed for each: M96 at 2,434 HP for 26 knots, M96L at 2,637 HP for 27.
SL120A — 121'1", 27 knots, 10 guests / 6 crew. Twin MTU 16V2000 M96Ls at 2,637 HP, 19,900 litres of fuel and 4,200 litres of fresh water on a 24'11" beam. The flagship of the line, and the asymmetric layout at its largest scale — the main deck freed for a full-beam owner's suite.
Note what speed does as you go up the range, because it is worth saying out loud: 29 knots on the SL86A and the SL90A, 28 on the SL96A, 26 or 27 on the SL110A depending on the engine, and 27 on the SL120A. You move up this line for volume and guest capacity, not for pace. The SL120A makes the point twice over — it runs exactly the MTU M96L package that is the SL110A's upgrade option, 2,637 HP a side, and turns eleven more feet of boat into the same 27 knots.
Our Take
The SL is the range where Sanlorenzo took the biggest risk and it paid off. When the first asymmetric hull appeared, a good many people in this business said it would not sell. It sold, and then it became the thing the yard is known for.
What I would tell anyone shopping this line is that the layout is not a preference, it is a decision. Walk one. It either makes sense to you in the first thirty seconds or it never will, and neither reaction is wrong. If it clicks, you get width where you actually spend time. If it does not, buy something symmetrical and stop paying attention to the argument.
The SL110A's engine options are the most interesting choice in the range: one knot separates the M96 from the M96L, 26 against 27. Nobody buys the upgrade for that knot. You buy it for the margin below maximum and for the next owner, who will want it. The SL120A settles that argument from the other direction — it carries the M96L as its published package and returns the same 27 knots on eleven more feet of hull, ten guests and six crew. That margin is what the bigger engine is actually for, and the SL120A is the proof.
On an 87- to 121-footer that will live among islands, get the draft from the build specification in writing. And note that the step to the SL120A costs you a sixth crew berth on top of the length. That is the figure you keep paying.

Frequently Asked Questions
Which SL model is the fastest?
The smallest one. The SL86A has a published maximum of 29 knots, against 28 for the SL96A, 27 for the SL120A, and 26 or 27 for the SL110A depending on engine package. That is the normal pattern as displacement rises, and it is worth saying plainly: you move up the SL line for volume and guest capacity, not for pace. The SL110A is the only one of the four where Sanlorenzo offers a choice of engines, publishing 26 knots for the MTU M96 and 27 for the M96L; the SL120A, 11 feet longer, runs that same M96L as its one package and publishes 27.
How many models are in the Sanlorenzo SL line?
Sanlorenzo's fleet page lists six: the SL80A, SL86A, SL90A, SL96A, SL110A and SL120A. Five of the six are reviewed here: the SL86A, SL90A, SL96A, SL110A and SL120A, spanning 87 to 121 feet.
