The Campion 582 CC 2007 vs Campion Allante 505i 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.

Size is the most obvious dividing line here. The Campion Allante 505i 2012 measures 17,1 feet overall (2012), giving it roughly 15,1 additional feet of deck space compared to the Campion 582 CC 2007 at 2,0 feet (2007). At 192 lbs and 128 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 150 hp, the Campion 582 CC 2007 has a 25-hp advantage over the Campion Allante 505i 2012's 125-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 582 CC 2007 carries 53 gallons versus 24 gallons in the Campion Allante 505i 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 505i 2012 caps at 6. 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Campion Allante 505i 2012 comes in at 1 lbs per hp versus 1 lbs per hp for the Campion 582 CC 2007. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
