The Campion 622i Sedan 2006 vs Campion Allante 705i SC 2011 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Campion Allante 705i SC 2011 measures 26,2 feet overall (2011), giving it roughly 5,2 additional feet of deck space compared to the Campion 622i Sedan 2006 at 21,0 feet (2006). Weight tells a clearer story for trailering families: the Campion Allante 705i SC 2011 tips the scales at 4 550 lbs - 840 lbs less than the Campion 622i Sedan 2006 at 3 710 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 320 hp, the Campion Allante 705i SC 2011 has a 95-hp advantage over the Campion 622i Sedan 2006's 225-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 2011 carries 69 gallons versus 50 gallons in the Campion 622i Sedan 2006. 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 2011 at 26,2 ft is the right call if deck space, comfort, and entertaining are top of your list. The Campion 622i Sedan 2006 at 21,0 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.
