The Beneteau 31 2007 vs Beneteau Antares 8.80 2011 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 31 2007 at 31,8 ft versus Beneteau Antares 8.80 2011 at 29,3 ft. Weight tells a clearer story for trailering families: the Beneteau 31 2007 tips the scales at 10 692 lbs — 2 537 lbs more than the Beneteau Antares 8.80 2011 at 8 155 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 8.80 2011 has a 279-hp advantage over the Beneteau 31 2007'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 8.80 2011 carries 106 gallons versus 34 gallons in the Beneteau 31 2007. 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 31 2007 is rated for 9 passengers, while the Beneteau Antares 8.80 2011 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau 31 2007 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau 31 2007 displaces 10 692 lbs — a 2 537-lb difference over the Beneteau Antares 8.80 2011 at 8 155 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.
The Beneteau 31 2007 uses Sloop rigging. For auxiliary power the Beneteau Antares 8.80 2011 carries a 300-hp engine against 21 hp on the Beneteau 31 2007. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
Bottom line: The Beneteau 31 2007 is the offshore and bluewater choice — at 10 692 lbs displacement and 32 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau Antares 8.80 2011 at 8 155 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
