When two boats share the same hull type — in this case both the Campion Allante 505ob 2012 and the Campion Explorer 552i SC 2012 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 Explorer 552i SC 2012 measures 20,8 feet overall (2012), giving it roughly 4,3 additional feet of deck space compared to the Campion Allante 505ob 2012 at 16,6 feet (2012). Weight tells a clearer story for trailering families: the Campion Explorer 552i SC 2012 tips the scales at 3 171 lbs — 3 043 lbs less than the Campion Allante 505ob 2012 at 128 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 225 hp, the Campion Explorer 552i SC 2012 has a 100-hp advantage over the Campion Allante 505ob 2012's 125-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 Explorer 552i SC 2012 carries 47 gallons versus 24 gallons in the Campion Allante 505ob 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 Explorer 552i SC 2012 is rated for 7 passengers, while the Campion Allante 505ob 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Explorer 552i SC 2012 could be the deciding factor.
