When two boats share the same hull type — in this case both the Campion Allante 535i 2012 and the Campion Chase 550i 2013 are deep vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department — Campion Allante 535i 2012 at 17,8 ft versus Campion Chase 550i 2013 at 20,2 ft. Weight tells a clearer story for trailering families: the Campion Chase 550i 2013 tips the scales at 2 886 lbs — 2 868 lbs less than the Campion Allante 535i 2012 at 18 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 170-hp advantage over the Campion Allante 535i 2012'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 550i 2013 carries 29 gallons versus 24 gallons in the Campion Allante 535i 2012. 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 550i 2013 at 20,2 ft is the right call if deck space, comfort, and entertaining are top of your list. The Campion Allante 535i 2012 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.
