The Azimut Yachts 80 Fly Flybridge 2018 vs Azimut Yachts Atlantis 51 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 80 Fly Flybridge 2018 measures 82,9 feet overall (2018), giving it roughly 29,8 additional feet of deck space compared to the Azimut Yachts Atlantis 51 2017 at 53,1 feet (2017). Weight tells a clearer story for trailering families: the Azimut Yachts 80 Fly Flybridge 2018 tips the scales at 141 096 lbs — 91 933 lbs more than the Azimut Yachts Atlantis 51 2017 at 49 163 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 1 550 hp, the Azimut Yachts 80 Fly Flybridge 2018 has a 950-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 80 Fly Flybridge 2018 carries 1 585 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.

For family outings this is probably the sharpest distinction between the two. The Azimut Yachts 80 Fly Flybridge 2018 is rated for 25 passengers, while the Azimut Yachts Atlantis 51 2017 caps at 16. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Azimut Yachts 80 Fly Flybridge 2018 could be the deciding factor.
