The Prestige Yachts 550 S 2016 vs Prestige Yachts 590 S 2020 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 600 hp, the Prestige Yachts 550 S 2016 has a 300-hp advantage over the Prestige Yachts 590 S 2020's 300-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Prestige Yachts 550 S 2016 carries 581 gallons versus 484 gallons in the Prestige Yachts 590 S 2020. 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 Prestige Yachts 590 S 2020 is rated for 18 passengers, while the Prestige Yachts 550 S 2016 caps at 16. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Prestige Yachts 590 S 2020 could be the deciding factor.
