Sanlorenzo Yachts SD90 2023 vs Sanlorenzo Yachts SX88 2022 — Same Brand, Different Boat

The Sanlorenzo Yachts SD90 2023 vs Sanlorenzo Yachts SX88 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.

The power gap is worth calling out. Rated to 1 200 hp, the Sanlorenzo Yachts SD90 2023 has a 400-hp advantage over the Sanlorenzo Yachts SX88 2022's 800-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 SD90 2023 carries 3 434 gallons versus 2 457 gallons in the Sanlorenzo Yachts SX88 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 SD90 2023 is rated for 28 passengers, while the Sanlorenzo Yachts SX88 2022 caps at 26. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sanlorenzo Yachts SD90 2023 could be the deciding factor.

Bottom line: Choose the Sanlorenzo Yachts SD90 2023 if your priority is putting more people on the water — it handles 28 passengers and at 91,9 ft it has the deck room to back that rating up comfortably. The Sanlorenzo Yachts SX88 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 26 that costs less to run day-to-day.
