The Campion Chase 600 OB BR 2010 is a modified-V design and the Campion Chase 600i BR 2012 is a deep-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 Chase 600 OB BR 2010 at 20,0 ft versus Campion Chase 600i BR 2012 at 21,5 ft. Weight tells a clearer story for trailering families: the Campion Chase 600i BR 2012 tips the scales at 3 400 lbs - 1 054 lbs less than the Campion Chase 600 OB BR 2010 at 2 346 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.
Both boats share a closely matched power ceiling - 300 hp for the Campion Chase 600 OB BR 2010 and 320 hp for the Campion Chase 600i BR 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads - 47 gal and 47 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Campion Chase 600 OB BR 2010 is rated for 10 passengers, while the Campion Chase 600i BR 2012 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Chase 600 OB BR 2010 could be the deciding factor.
Bottom line: Choose the Campion Chase 600 OB BR 2010 if your priority is putting more people on the water - it handles 10 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Campion Chase 600i BR 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
