Detailed Evaluation & Buyer Recommendation
Campion 580 O/B BR 2006 vs Campion Allante A20 IO SC 2022 — Same Brand, Different Boat
The Campion 580 O/B BR 2006 vs Campion Allante A20 IO SC 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 Campion Allante A20 IO SC 2022 measures 21,6 feet overall (2022), giving it roughly 3,6 additional feet of deck space compared to the Campion 580 O/B BR 2006 at 18,0 feet (2006). Weight tells a clearer story for trailering families: the Campion Allante A20 IO SC 2022 tips the scales at 3 400 lbs — 3 198 lbs less than the Campion 580 O/B BR 2006 at 202 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 350 hp, the Campion Allante A20 IO SC 2022 has a 150-hp advantage over the Campion 580 O/B BR 2006's 200-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Campion Allante A20 IO SC 2022 carries 42 gallons versus 28 gallons in the Campion 580 O/B BR 2006. 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 Campion 580 O/B BR 2006 is rated for 8 passengers, while the Campion Allante A20 IO SC 2022 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion 580 O/B BR 2006 could be the deciding factor.
Bottom line: Choose the Campion 580 O/B BR 2006 if your priority is putting more people on the water — it handles 8 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Campion Allante A20 IO SC 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
