The Azimut Yachts 52 Fly 1999 vs Azimut Yachts S6 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.

The power gap is worth calling out. Rated to 550 hp, the Azimut Yachts S6 2019 has a 103-hp advantage over the Azimut Yachts 52 Fly 1999's 447-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 S6 2019 carries 656 gallons versus 476 gallons in the Azimut Yachts 52 Fly 1999. 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 S6 2019 is rated for 18 passengers, while the Azimut Yachts 52 Fly 1999 caps at 15. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Azimut Yachts S6 2019 could be the deciding factor.
