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.

Campion 580 O/B BR 2006 vs Campion Allante A20 IO SC 2022 — Common Questions

Which is the larger boat — the Campion 580 O/B BR 2006 or the Campion Allante A20 IO SC 2022?
The Campion Allante A20 IO SC 2022 is the longer of the two at 21,6 feet overall. The Campion 580 O/B BR 2006 comes in at 18,0 feet, making it roughly 3,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Campion 580 O/B BR 2006 or the Campion Allante A20 IO SC 2022?
For trailering, the Campion 580 O/B BR 2006 has the edge at 202 lbs dry weight versus 3 400 lbs for the Campion Allante A20 IO SC 2022. 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 Campion Allante A20 IO SC 2022 is rated to a maximum of 350 hp, giving it the larger power ceiling. The Campion 580 O/B BR 2006 tops out at 200 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 Campion 580 O/B BR 2006 is Coast Guard rated for 8 passengers, while the Campion Allante A20 IO SC 2022 is certified for 6. 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 is wider, and does it affect trailering?
The Campion Allante A20 IO SC 2022 measures 98" wide, compared to 92" for the Campion 580 O/B BR 2006. 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 Campion 580 O/B BR 2006 or the Campion Allante A20 IO SC 2022?
The Campion Allante A20 IO SC 2022 has the bigger tank at 42 gallons, versus 28 gallons on the Campion 580 O/B BR 2006. That 14-gallon difference translates to roughly 42–70 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Campion 580 O/B BR 2006 and Campion Allante A20 IO SC 2022 from the same manufacturer?
Yes — both the Campion 580 O/B BR 2006 and the Campion Allante A20 IO SC 2022 are built by Campion. 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.
