The Campion 650i BR 2009 is a modified-V design and the Campion Chase 600ob 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 650i BR 2009 at 23,0 ft versus Campion Chase 600ob BR 2012 at 20,0 ft. Weight tells a clearer story for trailering families: the Campion 650i BR 2009 tips the scales at 4 210 lbs - 1 864 lbs more than the Campion Chase 600ob BR 2012 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.
The power gap is worth calling out. Rated to 375 hp, the Campion 650i BR 2009 has a 75-hp advantage over the Campion Chase 600ob BR 2012's 300-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 650i BR 2009 carries 56 gallons versus 47 gallons in the Campion Chase 600ob BR 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 Chase 600ob BR 2012 is rated for 10 passengers, while the Campion 650i BR 2009 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Chase 600ob BR 2012 could be the deciding factor.
Bottom line: Choose the Campion Chase 600ob BR 2012 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 650i BR 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
