Matching a modified vee Campion 645i SC 2009 against a deep vee Campion Chase 700i BR 2012 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.
Size is the most obvious dividing line here. The Campion Chase 700i BR 2012 measures 26,2 feet overall (2012), giving it roughly 3,2 additional feet of deck space compared to the Campion 645i SC 2009 at 23,0 feet (2009). Weight tells a clearer story for trailering families: the Campion 645i SC 2009 tips the scales at 4 037 lbs — 3 582 lbs more than the Campion Chase 700i BR 2012 at 455 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 430 hp, the Campion Chase 700i BR 2012 has a 110-hp advantage over the Campion 645i SC 2009's 320-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 Chase 700i BR 2012 carries 69 gallons versus 56 gallons in the Campion 645i SC 2009. 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 645i SC 2009 is rated for 9 passengers, while the Campion Chase 700i 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 645i SC 2009 could be the deciding factor.
Bottom line: Choose the Campion 645i SC 2009 if your priority is putting more people on the water — it handles 9 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Campion Chase 700i 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.
