The Campion Allante 595ob SC 2012 is a deep-V design and the Campion Explorer 602 CC 2011 is a modified-V design, so you're likely deciding between two noticeably 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 595ob SC 2012 at 21,0 ft versus Campion Explorer 602 CC 2011 at 22,3 ft. At 2 346 lbs and 2 300 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 300 hp, the Campion Allante 595ob SC 2012 has a 75-hp advantage over the Campion Explorer 602 CC 2011'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 Explorer 602 CC 2011 carries 64 gallons versus 47 gallons in the Campion Allante 595ob SC 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 Allante 595ob SC 2012 is rated for 10 passengers, while the Campion Explorer 602 CC 2011 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 595ob SC 2012 could be the deciding factor.
Bottom line: Choose the Campion Allante 595ob SC 2012 if your priority is putting more people on the water - it handles 10 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Campion Explorer 602 CC 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
