The Jeanneau NC 11 2018 vs Jeanneau Prestige 680S 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 900 hp, the Jeanneau Prestige 680S 2019 has a 700-hp advantage over the Jeanneau NC 11 2018's 200-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Jeanneau Prestige 680S 2019 carries 924 gallons versus 19 gallons in the Jeanneau NC 11 2018. 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 Jeanneau Prestige 680S 2019 is rated for 21 passengers, while the Jeanneau NC 11 2018 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Jeanneau Prestige 680S 2019 could be the deciding factor.
Bottom line: Choose the Jeanneau Prestige 680S 2019 if your priority is putting more people on the water — it handles 21 passengers and at 70,0 ft it has the deck room to back that rating up comfortably. The Jeanneau NC 11 2018 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
