The Campion 800i SC 2009 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 800i SC 2009 measures 28,0 feet overall (2009), giving it roughly 6,4 additional feet of deck space compared to the Campion Allante A20 IO SC 2022 at 21,6 feet (2022). Weight tells a clearer story for trailering families: the Campion 800i SC 2009 tips the scales at 4 855 lbs — 1 455 lbs more than the Campion Allante A20 IO SC 2022 at 3 400 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 460 hp, the Campion 800i SC 2009 has a 110-hp advantage over the Campion Allante A20 IO SC 2022's 350-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 800i SC 2009 carries 63 gallons versus 42 gallons in the Campion Allante A20 IO SC 2022. 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 800i SC 2009 is rated for 7 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 800i SC 2009 could be the deciding factor.
