The Campion 800i SC 2007 vs Campion Allante 535ob 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.
Size is the most obvious dividing line here. The Campion 800i SC 2007 measures 28,0 feet overall (2007), giving it roughly 10,2 additional feet of deck space compared to the Campion Allante 535ob 2013 at 17,8 feet (2013). Weight tells a clearer story for trailering families: the Campion 800i SC 2007 tips the scales at 4 855 lbs — 4 837 lbs more than the Campion Allante 535ob 2013 at 18 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 460 hp, the Campion 800i SC 2007 has a 310-hp advantage over the Campion Allante 535ob 2013's 150-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 800i SC 2007 carries 63 gallons versus 24 gallons in the Campion Allante 535ob 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 7 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 800i SC 2007 at 28,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Campion Allante 535ob 2013 at 17,8 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.
