The Campion 582 CC 2007 vs Campion Allante 535i 2012 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 582 CC 2007 at 20,0 ft versus Campion Allante 535i 2012 at 17,8 ft. Weight tells a clearer story for trailering families: the Campion 582 CC 2007 tips the scales at 1 920 lbs - 120 lbs more than the Campion Allante 535i 2012 at 1 800 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.
Both boats share a closely matched power ceiling - 150 hp for the Campion 582 CC 2007 and 150 hp for the Campion Allante 535i 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Campion 582 CC 2007 carries 53 gallons versus 24 gallons in the Campion Allante 535i 2012. 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 582 CC 2007 is rated for 8 passengers, while the Campion Allante 535i 2012 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion 582 CC 2007 could be the deciding factor.
Bottom line: Choose the Campion 582 CC 2007 if your priority is putting more people on the water - it handles 8 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Campion Allante 535i 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
