Sanlorenzo Yachts 46Steel 2015 vs Sanlorenzo Yachts SL106 Asymmetric 2020 — Same Brand, Different Boat

The Sanlorenzo Yachts 46Steel 2015 vs Sanlorenzo Yachts SL106 Asymmetric 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.

The power gap is worth calling out. Rated to 2 434 hp, the Sanlorenzo Yachts SL106 Asymmetric 2020 has a 394-hp advantage over the Sanlorenzo Yachts 46Steel 2015's 2 040-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 46Steel 2015 carries 13 472 gallons versus 1 875 gallons in the Sanlorenzo Yachts SL106 Asymmetric 2020. 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 46Steel 2015 is rated for 45 passengers, while the Sanlorenzo Yachts SL106 Asymmetric 2020 caps at 32. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sanlorenzo Yachts 46Steel 2015 could be the deciding factor.

Bottom line: Choose the Sanlorenzo Yachts 46Steel 2015 if your priority is putting more people on the water — it handles 45 passengers and at 150,9 ft it has the deck room to back that rating up comfortably. The Sanlorenzo Yachts SL106 Asymmetric 2020 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 32 that costs less to run day-to-day.
