Matching a modified vee Campion 650i SC 2009 against a deep vee Campion Allante 705i 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.
Size is the most obvious dividing line here. The Campion Allante 705i SC 2012 measures 26,2 feet overall (2012), giving it roughly 3,2 additional feet of deck space compared to the Campion 650i SC 2009 at 23,0 feet (2009). At 421 lbs and 455 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 430 hp, the Campion Allante 705i SC 2012 has a 55-hp advantage over the Campion 650i SC 2009's 375-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 SC 2012 carries 69 gallons versus 56 gallons in the Campion 650i SC 2009. 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.
Bottom line: The Campion Allante 705i SC 2012 at 26,2 ft is the right call if deck space, comfort, and entertaining are top of your list. The Campion 650i SC 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.
