Detailed Evaluation & Buyer Recommendation
Beneteau Antares 11 OB 2021 vs Beneteau Antares 13.80 2008 — Same Brand, Different Boat
The Beneteau Antares 11 OB 2021 vs Beneteau Antares 13.80 2008 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 Beneteau Antares 11 OB 2021 carries a rated maximum of 300 hp. Engine data for the Beneteau Antares 13.80 2008 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Beneteau Antares 13.80 2008 carries 396 gallons versus 106 gallons in the Beneteau Antares 11 OB 2021. 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 13.80 2008 is rated for 13 passengers, while the Beneteau Antares 11 OB 2021 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Antares 13.80 2008 could be the deciding factor.
Bottom line: Choose the Beneteau Antares 13.80 2008 if your priority is putting more people on the water — it handles 13 passengers and at 45,0 ft it has the deck room to back that rating up comfortably. The Beneteau Antares 11 OB 2021 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
