Sanlorenzo Yachts SD118 2022 vs Sanlorenzo Yachts SL120 Asymmetric 2021 — Same Brand, Different Boat

The Sanlorenzo Yachts SD118 2022 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.

The power gap is worth calling out. Rated to 2 000 hp, the Sanlorenzo Yachts SL120 Asymmetric 2021 has a 620-hp advantage over the Sanlorenzo Yachts SD118 2022's 1 380-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sanlorenzo Yachts SD118 2022 carries 8 453 gallons versus 3 619 gallons in the Sanlorenzo Yachts SL120 Asymmetric 2021. 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 SD118 2022 caps at 35. 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 SD118 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 35 that costs less to run day-to-day.
