Sanlorenzo Yachts 46Steel 2015 vs Sanlorenzo Yachts SX76 2018 — Same Brand, Different Boat

The Sanlorenzo Yachts 46Steel 2015 vs Sanlorenzo Yachts SX76 2018 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 2 040 hp, the Sanlorenzo Yachts 46Steel 2015 has a 1 240-hp advantage over the Sanlorenzo Yachts SX76 2018'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 46Steel 2015 carries 13 472 gallons versus 1 149 gallons in the Sanlorenzo Yachts SX76 2018. 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 SX76 2018 caps at 23. 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 SX76 2018 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 23 that costs less to run day-to-day.
