The Campion Allante 825 2013 vs Campion S 505i BR 2005 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 825 2013 measures 27,8 feet overall (2013), giving it roughly 11,8 additional feet of deck space compared to the Campion S 505i BR 2005 at 16,0 feet (2005). Weight tells a clearer story for trailering families: the Campion Allante 825 2013 tips the scales at 8 422 lbs — 6 448 lbs more than the Campion S 505i BR 2005 at 1 974 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 430 hp, the Campion Allante 825 2013 has a 295-hp advantage over the Campion S 505i BR 2005's 135-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 825 2013 carries 111 gallons versus 19 gallons in the Campion S 505i BR 2005. 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 825 2013 is rated for 12 passengers, while the Campion S 505i BR 2005 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Allante 825 2013 could be the deciding factor.
