The Campion 705i SC 2009 is a modified-V design and the Campion Allante 645i SC 2012 is a deep-V design, so you're likely deciding between two noticeably 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 705i SC 2009 at 26,0 ft versus Campion Allante 645i SC 2012 at 25,1 ft. Weight tells a clearer story for trailering families: the Campion 705i SC 2009 tips the scales at 4 550 lbs - 513 lbs more than the Campion Allante 645i SC 2012 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 380 hp, the Campion Allante 645i SC 2012 has a 60-hp advantage over the Campion 705i 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 705i SC 2009 carries 69 gallons versus 56 gallons in the Campion Allante 645i SC 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 9 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
