The Beneteau Antares 9.80 2005 vs Beneteau Oceanis 55.1 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 Oceanis 55.1 2022 measures 55,1 feet overall (2022), giving it roughly 25,1 additional feet of deck space compared to the Beneteau Antares 9.80 2005 at 30,0 feet (2005). Weight tells a clearer story for trailering families: the Beneteau Oceanis 55.1 2022 tips the scales at 10 053 lbs — 530 lbs less than the Beneteau Antares 9.80 2005 at 9 523 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 150-hp advantage over the Beneteau Oceanis 55.1 2022's 110-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 106 gal and 106 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Beneteau Oceanis 55.1 2022 is rated for 16 passengers, while the Beneteau Antares 9.80 2005 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Oceanis 55.1 2022 could be the deciding factor.

Both boats sit in a similar displacement bracket — 9 523 lbs for the Beneteau Antares 9.80 2005 and 10 053 lbs for the Beneteau Oceanis 55.1 2022. Comparable displacement means broadly similar seakeeping behaviour and load capacity, though hull form and ballast ratio will still produce noticeably different sailing characteristics.

Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Beneteau Oceanis 55.1 2022 draws 7,6 ft, compared to 2,7 ft for the Beneteau Antares 9.80 2005. That 4,9-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 110 hp on the Beneteau Oceanis 55.1 2022. 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 Oceanis 55.1 2022 carries 183 gallons versus 25 gallons on the Beneteau Antares 9.80 2005 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
