Matching a modified vee Campion 602i SC 2009 against a deep vee Campion Allante 645i SC 2012 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.

On paper these two are close siblings in the size department — Campion 602i SC 2009 at 23,0 ft versus Campion Allante 645i SC 2012 at 25,1 ft. Weight tells a clearer story for trailering families: the Campion Allante 645i SC 2012 tips the scales at 4 037 lbs — 3 998 lbs less than the Campion 602i SC 2009 at 39 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 380 hp, the Campion Allante 645i SC 2012 has a 60-hp advantage over the Campion 602i SC 2009's 320-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 Allante 645i SC 2012 carries 56 gallons versus 6 gallons in the Campion 602i SC 2009. 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 2012 is rated for 9 passengers, while the Campion 602i SC 2009 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Allante 645i SC 2012 could be the deciding factor.
