The Prestige Yachts 550 S 2016 vs Prestige Yachts 680 S 2018 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 1 000 hp, the Prestige Yachts 680 S 2018 has a 400-hp advantage over the Prestige Yachts 550 S 2016'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 Prestige Yachts 680 S 2018 carries 911 gallons versus 581 gallons in the Prestige Yachts 550 S 2016. 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 680 S 2018 is rated for 19 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 680 S 2018 could be the deciding factor.
