Matching a modified vee Campion Allante 645i SC 2010 against a deep vee Campion Allante 925 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 2010 measures 23,1 feet overall (2010), giving it roughly 20,1 additional feet of deck space compared to the Campion Allante 925 2013 at 3,0 feet (2013). Weight tells a clearer story for trailering families: the Campion Allante 645i SC 2010 tips the scales at 4 037 lbs — 2 991 lbs more than the Campion Allante 925 2013 at 1 046 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 640 hp, the Campion Allante 925 2013 has a 320-hp advantage over the Campion Allante 645i SC 2010'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 925 2013 carries 111 gallons versus 56 gallons in the Campion Allante 645i SC 2010. 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 2010 is rated for 9 passengers, while the Campion Allante 925 2013 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 2010 could be the deciding factor.
