Sanlorenzo Yachts SL118 2016 vs Sanlorenzo Yachts SL120 Asymmetric 2021 — Same Brand, Different Boat

The Sanlorenzo Yachts SL118 2016 vs Sanlorenzo Yachts SL120 Asymmetric 2021 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Sanlorenzo Yachts SL118 2016 at 119,7 ft versus Sanlorenzo Yachts SL120 Asymmetric 2021 at 121,0 ft. At 385 809 lbs and 385 809 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 2 637 hp, the Sanlorenzo Yachts SL118 2016 has a 637-hp advantage over the Sanlorenzo Yachts SL120 Asymmetric 2021's 2 000-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 3 619 gal and 3 619 gal — so range won't be a tiebreaker here.

Both boats are rated for 36 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: Performance buyers should lean toward the Sanlorenzo Yachts SL118 2016 and its 2 637-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sanlorenzo Yachts SL120 Asymmetric 2021 with its 2 000-hp rating is the more economical daily driver.

Which is the larger boat — the Sanlorenzo Yachts SL118 2016 or the Sanlorenzo Yachts SL120 Asymmetric 2021?
The Sanlorenzo Yachts SL120 Asymmetric 2021 is the longer of the two at 121,0 feet overall. The Sanlorenzo Yachts SL118 2016 comes in at 119,7 feet, making it roughly 1,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sanlorenzo Yachts SL118 2016 or the Sanlorenzo Yachts SL120 Asymmetric 2021?
For trailering, the Sanlorenzo Yachts SL120 Asymmetric 2021 has the edge at 385 809 lbs dry weight versus 385 809 lbs for the Sanlorenzo Yachts SL118 2016. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Sanlorenzo Yachts SL118 2016 is rated to a maximum of 2 637 hp, giving it the larger power ceiling. The Sanlorenzo Yachts SL120 Asymmetric 2021 tops out at 2 000 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Sanlorenzo Yachts SL118 2016 is Coast Guard rated for 36 passengers, while the Sanlorenzo Yachts SL120 Asymmetric 2021 is certified for 36. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Sanlorenzo Yachts SL118 2016 measures 299" wide, compared to 289" for the Sanlorenzo Yachts SL120 Asymmetric 2021. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
How do the fuel tanks compare on the Sanlorenzo Yachts SL118 2016 and Sanlorenzo Yachts SL120 Asymmetric 2021?
Both boats carry similar fuel loads — 3 619 gallons and 3 619 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Sanlorenzo Yachts SL118 2016 and Sanlorenzo Yachts SL120 Asymmetric 2021 from the same manufacturer?
Yes — both the Sanlorenzo Yachts SL118 2016 and the Sanlorenzo Yachts SL120 Asymmetric 2021 are built by Sanlorenzo Yachts. That means shared dealer networks, common parts availability, and consistent build quality across the line.
