Matching a modified vee Campion Allante 645i BR 2010 against a deep vee Campion Explorer 552i SC 2013 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Campion Allante 645i BR 2010 at 23,1 ft versus Campion Explorer 552i SC 2013 at 20,8 ft. Weight tells a clearer story for trailering families: the Campion Allante 645i BR 2010 tips the scales at 4 037 lbs — 866 lbs more than the Campion Explorer 552i SC 2013 at 3 171 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 320 hp, the Campion Allante 645i BR 2010 has a 95-hp advantage over the Campion Explorer 552i SC 2013's 225-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 645i BR 2010 carries 56 gallons versus 47 gallons in the Campion Explorer 552i SC 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 645i BR 2010 is rated for 9 passengers, while the Campion Explorer 552i SC 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 645i BR 2010 could be the deciding factor.
Bottom line: Choose the Campion Allante 645i BR 2010 if your priority is putting more people on the water — it handles 9 passengers and at 23,1 ft it has the deck room to back that rating up comfortably. The Campion Explorer 552i SC 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
