Beneteau Antares 11 2020 vs Beneteau First 31.7 1997 — Same Brand, Different Boat

The Beneteau Antares 11 2020 vs Beneteau First 31.7 1997 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.

On paper these two are close siblings in the size department — Beneteau Antares 11 2020 at 32,6 ft versus Beneteau First 31.7 1997 at 31,6 ft. Weight tells a clearer story for trailering families: the Beneteau Antares 11 2020 tips the scales at 13 451 lbs — 5 184 lbs more than the Beneteau First 31.7 1997 at 8 267 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 2020 has a 279-hp advantage over the Beneteau First 31.7 1997's 21-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 2020 carries 212 gallons versus 8 gallons in the Beneteau First 31.7 1997. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 9 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Displacement is where these two sailboats genuinely part ways. The Beneteau Antares 11 2020 displaces 13 451 lbs — a 5 184-lb difference over the Beneteau First 31.7 1997 at 8 267 lbs. That gap separates two entirely different categories of sailing: the heavier boat is built for offshore passage-making and load-carrying, while the lighter hull rewards performance sailing and easier handling in lighter air.

Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Beneteau First 31.7 1997 draws 6,2 ft, compared to 2,7 ft for the Beneteau Antares 11 2020. That 3,5-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.

For auxiliary power the Beneteau Antares 11 2020 carries a 300-hp engine against 21 hp on the Beneteau First 31.7 1997. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.

For extended cruising, water capacity matters: the Beneteau Antares 11 2020 carries 53 gallons versus 42 gallons on the Beneteau First 31.7 1997 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.

Bottom line: The Beneteau Antares 11 2020 is the offshore and bluewater choice — at 13 451 lbs displacement and 33 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau First 31.7 1997 at 8 267 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.

Beneteau Antares 11 2020 vs Beneteau First 31.7 1997 — Common Questions

Which is the larger boat — the Beneteau Antares 11 2020 or the Beneteau First 31.7 1997?
The Beneteau Antares 11 2020 is the longer of the two at 32,6 feet overall. The Beneteau First 31.7 1997 comes in at 31,6 feet, making it roughly 1,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Beneteau Antares 11 2020 or the Beneteau First 31.7 1997?
For trailering, the Beneteau First 31.7 1997 has the edge at 8 267 lbs dry weight versus 13 451 lbs for the Beneteau Antares 11 2020. 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 Antares 11 2020 is rated to a maximum of 300 hp, giving it the larger power ceiling. The Beneteau First 31.7 1997 tops out at 21 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 2020 is Coast Guard rated for 9 passengers, while the Beneteau First 31.7 1997 is certified for 9. 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 has the deeper draft — the Beneteau Antares 11 2020 or the Beneteau First 31.7 1997?
The Beneteau First 31.7 1997 has the deeper draft at 6,2 ft, versus 2,7 ft for the Beneteau Antares 11 2020. A deeper draft generally means better upwind performance and stability, but limits access to shallow anchorages and some marina berths. Always check the controlling depth of your home port and favourite cruising grounds before committing.
Is the Beneteau Antares 11 2020 or the Beneteau First 31.7 1997 better suited for offshore sailing?
For offshore work, displacement and construction are the primary indicators. The Beneteau Antares 11 2020 at 13 451 lbs displacement is the heavier, more load-carrying design — generally better suited to extended passages where seakeeping and provisioning capacity matter most. The Beneteau First 31.7 1997 at 8 267 lbs will typically be livelier and more responsive in lighter conditions.
Which boat is better equipped for long-distance cruising?
For extended passages, fresh water capacity is a key indicator of cruising readiness. The Beneteau Antares 11 2020 carries 53 gallons of fresh water compared to 42 gallons on the Beneteau First 31.7 1997 — a meaningful advantage when watermaker installations or port stops aren't guaranteed.
Which boat is wider, and does it affect trailering?
The Beneteau Antares 11 2020 measures 139" wide, compared to 128" for the Beneteau First 31.7 1997. 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 2020 or the Beneteau First 31.7 1997?
The Beneteau Antares 11 2020 has the bigger tank at 212 gallons, versus 8 gallons on the Beneteau First 31.7 1997. That 204-gallon difference translates to roughly 612–1020 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Beneteau Antares 11 2020 and Beneteau First 31.7 1997 from the same manufacturer?
Yes — both the Beneteau Antares 11 2020 and the Beneteau First 31.7 1997 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.
