Sanlorenzo Yachts SL120 Asymmetric 2021 vs Sanlorenzo Yachts SL90 Asymmetric 2022 — Same Brand, Different Boat

The Sanlorenzo Yachts SL120 Asymmetric 2021 vs Sanlorenzo Yachts SL90 Asymmetric 2022 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.

Size is the most obvious dividing line here. The Sanlorenzo Yachts SL120 Asymmetric 2021 measures 121,0 feet overall (2021), giving it roughly 30,4 additional feet of deck space compared to the Sanlorenzo Yachts SL90 Asymmetric 2022 at 90,6 feet (2022). Weight tells a clearer story for trailering families: the Sanlorenzo Yachts SL120 Asymmetric 2021 tips the scales at 385 809 lbs — 143 301 lbs more than the Sanlorenzo Yachts SL90 Asymmetric 2022 at 242 508 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

Both boats share a closely matched power ceiling — 2 000 hp for the Sanlorenzo Yachts SL120 Asymmetric 2021 and 2 000 hp for the Sanlorenzo Yachts SL90 Asymmetric 2022. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Sanlorenzo Yachts SL120 Asymmetric 2021 carries 3 619 gallons versus 2 377 gallons in the Sanlorenzo Yachts SL90 Asymmetric 2022. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Sanlorenzo Yachts SL120 Asymmetric 2021 is rated for 36 passengers, while the Sanlorenzo Yachts SL90 Asymmetric 2022 caps at 27. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sanlorenzo Yachts SL120 Asymmetric 2021 could be the deciding factor.

Bottom line: Choose the Sanlorenzo Yachts SL120 Asymmetric 2021 if your priority is putting more people on the water — it handles 36 passengers and at 121,0 ft it has the deck room to back that rating up comfortably. The Sanlorenzo Yachts SL90 Asymmetric 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 27 that costs less to run day-to-day.
