The Campion 622i Sedan 2008 vs Campion Allante 645i SC 2013 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.
On paper these two are close siblings in the size department — Campion 622i Sedan 2008 at 23,0 ft versus Campion Allante 645i SC 2013 at 25,1 ft. Weight tells a clearer story for trailering families: the Campion 622i Sedan 2008 tips the scales at 4 392 lbs — 355 lbs more 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 155-hp advantage over the Campion 622i Sedan 2008'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 645i SC 2013 carries 56 gallons versus 50 gallons in the Campion 622i Sedan 2008. 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 645i SC 2013 at 25,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The Campion 622i Sedan 2008 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.
