Beneteau Antares 11 OB 2021 vs Beneteau Flyer 9 Spacedeck 2022 — Same Brand, Different Boat

The Beneteau Antares 11 OB 2021 vs Beneteau Flyer 9 Spacedeck 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 3,5 additional feet of deck space compared to the Beneteau Flyer 9 Spacedeck 2022 at 29,1 feet (2022). Weight tells a clearer story for trailering families: the Beneteau Antares 11 OB 2021 tips the scales at 13 451 lbs — 6 059 lbs more than the Beneteau Flyer 9 Spacedeck 2022 at 7 392 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 500 hp, the Beneteau Flyer 9 Spacedeck 2022 has a 200-hp advantage over the Beneteau Antares 11 OB 2021'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 Beneteau Flyer 9 Spacedeck 2022 carries 152 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 11 OB 2021 is rated for 9 passengers, while the Beneteau Flyer 9 Spacedeck 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 Flyer 9 Spacedeck 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.

Beneteau Antares 11 OB 2021 vs Beneteau Flyer 9 Spacedeck 2022 — Common Questions

Which is the larger boat — the Beneteau Antares 11 OB 2021 or the Beneteau Flyer 9 Spacedeck 2022?
The Beneteau Antares 11 OB 2021 is the longer of the two at 32,6 feet overall. The Beneteau Flyer 9 Spacedeck 2022 comes in at 29,1 feet, making it roughly 3,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Beneteau Antares 11 OB 2021 or the Beneteau Flyer 9 Spacedeck 2022?
For trailering, the Beneteau Flyer 9 Spacedeck 2022 has the edge at 7 392 lbs dry weight versus 13 451 lbs for the Beneteau Antares 11 OB 2021. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Beneteau Flyer 9 Spacedeck 2022 is rated to a maximum of 500 hp, giving it the larger power ceiling. The Beneteau Antares 11 OB 2021 tops out at 300 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Beneteau Antares 11 OB 2021 is Coast Guard rated for 9 passengers, while the Beneteau Flyer 9 Spacedeck 2022 is certified for 8. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Beneteau Antares 11 OB 2021 measures 139" wide, compared to 109" for the Beneteau Flyer 9 Spacedeck 2022. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Beneteau Antares 11 OB 2021 or the Beneteau Flyer 9 Spacedeck 2022?
The Beneteau Flyer 9 Spacedeck 2022 has the bigger tank at 152 gallons, versus 106 gallons on the Beneteau Antares 11 OB 2021. That 46-gallon difference translates to roughly 138–230 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Beneteau Antares 11 OB 2021 and Beneteau Flyer 9 Spacedeck 2022 from the same manufacturer?
Yes — both the Beneteau Antares 11 OB 2021 and the Beneteau Flyer 9 Spacedeck 2022 are built by Beneteau. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
