Matching a deep vee Campion Allante 645i SC 2013 against a modified vee Campion Allante 705i BR 2011 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 Allante 645i SC 2013 at 25,1 ft versus Campion Allante 705i BR 2011 at 26,2 ft. Weight tells a clearer story for trailering families: the Campion Allante 705i BR 2011 tips the scales at 4 627 lbs — 590 lbs less 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 380 hp, the Campion Allante 645i SC 2013 has a 60-hp advantage over the Campion Allante 705i BR 2011'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 705i BR 2011 carries 69 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.

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.
