Matching a modified vee Campion 650i BR 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 650i BR 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 — 3 616 lbs less than the Campion 650i BR 2009 at 421 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.
Both boats share a closely matched power ceiling — 375 hp for the Campion 650i BR 2009 and 380 hp for the Campion Allante 645i SC 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. 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.
Bottom line: The Campion Allante 645i SC 2012 at 25,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The Campion 650i BR 2009 at 23,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
