The Beneteau Antares 9.80 2005 vs Beneteau Idylle 8.80 1982 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 9.80 2005 at 30,0 ft versus Beneteau Idylle 8.80 1982 at 28,1 ft. Weight tells a clearer story for trailering families: the Beneteau Antares 9.80 2005 tips the scales at 9 523 lbs — 2 138 lbs more than the Beneteau Idylle 8.80 1982 at 7 385 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 260 hp, the Beneteau Antares 9.80 2005 has a 230-hp advantage over the Beneteau Idylle 8.80 1982's 30-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 9.80 2005 carries 106 gallons versus 21 gallons in the Beneteau Idylle 8.80 1982. 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 9.80 2005 is rated for 9 passengers, while the Beneteau Idylle 8.80 1982 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 9.80 2005 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Beneteau Antares 9.80 2005 displaces 9 523 lbs — a 2 138-lb difference over the Beneteau Idylle 8.80 1982 at 7 385 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 Idylle 8.80 1982 draws 4,1 ft, compared to 2,7 ft for the Beneteau Antares 9.80 2005. That 1,4-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 9.80 2005 carries a 260-hp engine against 30 hp on the Beneteau Idylle 8.80 1982. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
