The Azimut Yachts Atlantis 58 2011 vs Azimut Yachts S77 2017 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.

Size is the most obvious dividing line here. The Azimut Yachts S77 2017 measures 77,4 feet overall (2017), giving it roughly 15,4 additional feet of deck space compared to the Azimut Yachts Atlantis 58 2011 at 62,0 feet (2011). Weight tells a clearer story for trailering families: the Azimut Yachts S77 2017 tips the scales at 127 868 lbs — 63 934 lbs less than the Azimut Yachts Atlantis 58 2011 at 63 934 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 1 000 hp, the Azimut Yachts Atlantis 58 2011 has a 100-hp advantage over the Azimut Yachts S77 2017's 900-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Azimut Yachts S77 2017 carries 1 056 gallons versus 793 gallons in the Azimut Yachts Atlantis 58 2011. 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 Azimut Yachts S77 2017 is rated for 23 passengers, while the Azimut Yachts Atlantis 58 2011 caps at 18. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Azimut Yachts S77 2017 could be the deciding factor.
