The Campion 800i SC 2008 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.
On paper these two are close siblings in the size department — Campion 800i SC 2008 at 28,0 ft versus Campion Allante 705i SC 2011 at 26,2 ft. Weight tells a clearer story for trailering families: the Campion 800i SC 2008 tips the scales at 4 855 lbs — 4 400 lbs more than the Campion Allante 705i SC 2011 at 455 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 2008 has a 140-hp advantage over the Campion Allante 705i SC 2011's 320-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 63 gallons in the Campion 800i SC 2008. 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 Allante 705i SC 2011 is rated for 9 passengers, while the Campion 800i SC 2008 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Allante 705i SC 2011 could be the deciding factor.
Bottom line: Choose the Campion Allante 705i SC 2011 if your priority is putting more people on the water — it handles 9 passengers and at 26,2 ft it has the deck room to back that rating up comfortably. The Campion 800i SC 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
