Campion 580i BR 2005 vs Campion Allante A18 OB BR 2022 — Same Brand, Different Boat

The Campion 580i BR 2005 vs Campion Allante A18 OB BR 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.

On paper these two are close siblings in the size department — Campion 580i BR 2005 at 19,0 ft versus Campion Allante A18 OB BR 2022 at 18,0 ft. Weight tells a clearer story for trailering families: the Campion Allante A18 OB BR 2022 tips the scales at 1 955 lbs — 1 930 lbs less than the Campion 580i BR 2005 at 25 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 320 hp, the Campion 580i BR 2005 has a 170-hp advantage over the Campion Allante A18 OB BR 2022's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 28 gal and 25 gal — so range won't be a tiebreaker here.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: Performance buyers should lean toward the Campion 580i BR 2005 and its 320-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Campion Allante A18 OB BR 2022 with its 150-hp rating is the more economical daily driver.

Campion 580i BR 2005 vs Campion Allante A18 OB BR 2022 — Common Questions

Which is the larger boat — the Campion 580i BR 2005 or the Campion Allante A18 OB BR 2022?
The Campion 580i BR 2005 is the longer of the two at 19,0 feet overall. The Campion Allante A18 OB BR 2022 comes in at 18,0 feet, making it roughly 1,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Campion 580i BR 2005 or the Campion Allante A18 OB BR 2022?
For trailering, the Campion 580i BR 2005 has the edge at 25 lbs dry weight versus 1 955 lbs for the Campion Allante A18 OB BR 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 580i BR 2005 is rated to a maximum of 320 hp, giving it the larger power ceiling. The Campion Allante A18 OB BR 2022 tops out at 150 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 580i BR 2005 is Coast Guard rated for 5 passengers, while the Campion Allante A18 OB BR 2022 is certified for 5. 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 A18 OB BR 2022 measures 94" wide, compared to 92" for the Campion 580i BR 2005. 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 580i BR 2005 or the Campion Allante A18 OB BR 2022?
The Campion 580i BR 2005 has the bigger tank at 28 gallons, versus 25 gallons on the Campion Allante A18 OB BR 2022. That 3-gallon difference translates to roughly 9–15 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Campion 580i BR 2005 and Campion Allante A18 OB BR 2022 from the same manufacturer?
Yes — both the Campion 580i BR 2005 and the Campion Allante A18 OB BR 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.
