The Campion Allante 645i BR 2011 is a modified-V design and the Campion Allante 645i SC 2013 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 Allante 645i BR 2011 at 23,1 ft versus Campion Allante 645i SC 2013 at 25,1 ft. At 4 037 lbs and 4 037 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

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 645i BR 2011's 320-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 56 gal and 56 gal - so range won't be a tiebreaker here.

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.
