The Azimut Yachts 55 Fly 2017 vs Azimut Yachts Atlantis 45 2019 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 55 Fly 2017 measures 55,4 feet overall (2017), giving it roughly 8,3 additional feet of deck space compared to the Azimut Yachts Atlantis 45 2019 at 47,1 feet (2019). Weight tells a clearer story for trailering families: the Azimut Yachts 55 Fly 2017 tips the scales at 63 934 lbs — 27 338 lbs more than the Azimut Yachts Atlantis 45 2019 at 36 596 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 800 hp, the Azimut Yachts 55 Fly 2017 has a 360-hp advantage over the Azimut Yachts Atlantis 45 2019's 440-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 55 Fly 2017 carries 676 gallons versus 264 gallons in the Azimut Yachts Atlantis 45 2019. 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 55 Fly 2017 is rated for 16 passengers, while the Azimut Yachts Atlantis 45 2019 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Azimut Yachts 55 Fly 2017 could be the deciding factor.
Bottom line: Choose the Azimut Yachts 55 Fly 2017 if your priority is putting more people on the water — it handles 16 passengers and at 55,4 ft it has the deck room to back that rating up comfortably. The Azimut Yachts Atlantis 45 2019 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.
