When two boats share the same hull type — in this case both the Campion Allante 545i 2012 and the Campion Chase 580ob 2012 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 545i 2012 at 20,2 ft versus Campion Chase 580ob 2012 at 19,2 ft. Weight tells a clearer story for trailering families: the Campion Allante 545i 2012 tips the scales at 2 886 lbs — 2 684 lbs more than the Campion Chase 580ob 2012 at 202 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 225 hp, the Campion Allante 545i 2012 has a 25-hp advantage over the Campion Chase 580ob 2012's 200-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 29 gal and 28 gal — so range won't be a tiebreaker here.
Both boats are rated for 8 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: Performance buyers should lean toward the Campion Allante 545i 2012 and its 225-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Campion Chase 580ob 2012 with its 200-hp rating is the more economical daily driver.
