Sanlorenzo Yachts SL86 2021 vs Sanlorenzo Yachts The Alloy 2020 — Same Brand, Different Boat

The Sanlorenzo Yachts SL86 2021 vs Sanlorenzo Yachts The Alloy 2020 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.

Both boats share a closely matched power ceiling — 1 947 hp for the Sanlorenzo Yachts SL86 2021 and 1 939 hp for the Sanlorenzo Yachts The Alloy 2020. 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 The Alloy 2020 carries 10 931 gallons versus 22 gallons in the Sanlorenzo Yachts SL86 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 The Alloy 2020 is rated for 43 passengers, while the Sanlorenzo Yachts SL86 2021 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 The Alloy 2020 could be the deciding factor.

Bottom line: Choose the Sanlorenzo Yachts The Alloy 2020 if your priority is putting more people on the water — it handles 43 passengers and at 144,0 ft it has the deck room to back that rating up comfortably. The Sanlorenzo Yachts SL86 2021 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 26 that costs less to run day-to-day.
