Matching a modified vee Campion Allante 485 BR 2011 against a deep vee Campion Chase 550i 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.
Size is the most obvious dividing line here. The Campion Chase 550i 2013 measures 20,2 feet overall (2013), giving it roughly 4,1 additional feet of deck space compared to the Campion Allante 485 BR 2011 at 16,1 feet (2011). Weight tells a clearer story for trailering families: the Campion Chase 550i 2013 tips the scales at 2 886 lbs — 2 792 lbs less than the Campion Allante 485 BR 2011 at 94 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 Chase 550i 2013 has a 230-hp advantage over the Campion Allante 485 BR 2011's 90-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 550i 2013 carries 29 gallons versus 13 gallons in the Campion Allante 485 BR 2011. 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 550i 2013 is rated for 7 passengers, while the Campion Allante 485 BR 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Chase 550i 2013 could be the deciding factor.
Bottom line: Choose the Campion Chase 550i 2013 if your priority is putting more people on the water — it handles 7 passengers and at 20,2 ft it has the deck room to back that rating up comfortably. The Campion Allante 485 BR 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
