When two boats share the same hull type — in this case both the Campion Allante 535ob 2013 and the Campion Allante 825 2013 are deep vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Campion Allante 825 2013 measures 27,8 feet overall (2013), giving it roughly 10,0 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 Allante 825 2013 tips the scales at 8 422 lbs — 8 404 lbs less 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 430 hp, the Campion Allante 825 2013 has a 280-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 Allante 825 2013 carries 111 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.

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 Allante 535ob 2013 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 825 2013 could be the deciding factor.
