The Campion 800i SC 2005 vs Campion Allante 535ob 2012 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 2005 measures 26,0 feet overall (2005), giving it roughly 8,2 additional feet of deck space compared to the Campion Allante 535ob 2012 at 17,8 feet (2012). Weight tells a clearer story for trailering families: the Campion 800i SC 2005 tips the scales at 461 lbs — 443 lbs more than the Campion Allante 535ob 2012 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 2005 has a 310-hp advantage over the Campion Allante 535ob 2012'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 2005 carries 63 gallons versus 24 gallons in the Campion Allante 535ob 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Campion 800i SC 2005 is rated for 8 passengers, while the Campion Allante 535ob 2012 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion 800i SC 2005 could be the deciding factor.
Bottom line: Choose the Campion 800i SC 2005 if your priority is putting more people on the water — it handles 8 passengers and at 26,0 ft it has the deck room to back that rating up comfortably. The Campion Allante 535ob 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
