The Beneteau Antares 11 OB 2021 vs Beneteau Antares 8 2022 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 Beneteau Antares 11 OB 2021 measures 32,6 feet overall (2021), giving it roughly 6,1 additional feet of deck space compared to the Beneteau Antares 8 2022 at 26,5 feet (2022). Weight tells a clearer story for trailering families: the Beneteau Antares 11 OB 2021 tips the scales at 13 451 lbs — 7 842 lbs more than the Beneteau Antares 8 2022 at 5 609 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 300 hp, the Beneteau Antares 11 OB 2021 has a 50-hp advantage over the Beneteau Antares 8 2022's 250-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Beneteau Antares 11 OB 2021 carries 106 gallons versus 9 gallons in the Beneteau Antares 8 2022. 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 Beneteau Antares 11 OB 2021 is rated for 9 passengers, while the Beneteau Antares 8 2022 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Antares 11 OB 2021 could be the deciding factor.
Bottom line: Choose the Beneteau Antares 11 OB 2021 if your priority is putting more people on the water — it handles 9 passengers and at 32,6 ft it has the deck room to back that rating up comfortably. The Beneteau Antares 8 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
