Matching a modified vee Campion 822i SC 2009 against a deep vee Campion Allante 645i SC 2013 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Campion Allante 645i SC 2013 measures 25,1 feet overall (2013), giving it roughly 22,1 additional feet of deck space compared to the Campion 822i SC 2009 at 3,0 feet (2009). Weight tells a clearer story for trailering families: the Campion 822i SC 2009 tips the scales at 7 877 lbs — 3 840 lbs more than the Campion Allante 645i SC 2013 at 4 037 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 425 hp, the Campion 822i SC 2009 has a 45-hp advantage over the Campion Allante 645i SC 2013's 380-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 822i SC 2009 carries 147 gallons versus 56 gallons in the Campion Allante 645i SC 2013. 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 Allante 645i SC 2013 is rated for 9 passengers, while the Campion 822i SC 2009 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Allante 645i SC 2013 could be the deciding factor.
