The Campion Allante 535 BR 2011 is a modified-V design and the Campion Chase 600i SC 2013 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.
Size is the most obvious dividing line here. The Campion Chase 600i SC 2013 measures 21,5 feet overall (2013), giving it roughly 3,7 additional feet of deck space compared to the Campion Allante 535 BR 2011 at 17,8 feet (2011). Weight tells a clearer story for trailering families: the Campion Chase 600i SC 2013 tips the scales at 3 400 lbs - 1 600 lbs less than the Campion Allante 535 BR 2011 at 1 800 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 600i SC 2013 has a 170-hp advantage over the Campion Allante 535 BR 2011's 150-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 600i SC 2013 carries 47 gallons versus 24 gallons in the Campion Allante 535 BR 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 7 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Campion Chase 600i SC 2013 at 21,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Campion Allante 535 BR 2011 at 17,8 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
