The Azimut Yachts Atlantis 51 2017 vs Azimut Yachts Atlantis 58 2011 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 Atlantis 58 2011 measures 62,0 feet overall (2011), giving it roughly 8,9 additional feet of deck space compared to the Azimut Yachts Atlantis 51 2017 at 53,1 feet (2017).

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 400-hp advantage over the Azimut Yachts Atlantis 51 2017's 600-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 Atlantis 58 2011 carries 793 gallons versus 396 gallons in the Azimut Yachts Atlantis 51 2017. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Azimut Yachts Atlantis 58 2011 could be the deciding factor.
