Matching a modified vee Campion 580 BR 2009 against a deep vee Campion Allante 535i 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.
On paper these two are close siblings in the size department — Campion 580 BR 2009 at 19,0 ft versus Campion Allante 535i 2013 at 17,8 ft. Weight tells a clearer story for trailering families: the Campion 580 BR 2009 tips the scales at 202 lbs — 178 lbs more than the Campion Allante 535i 2013 at 24 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 200 hp, the Campion 580 BR 2009 has a 50-hp advantage over the Campion Allante 535i 2013'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 580 BR 2009 carries 28 gallons versus 24 gallons in the Campion Allante 535i 2013. 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 580 BR 2009 is rated for 8 passengers, while the Campion Allante 535i 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion 580 BR 2009 could be the deciding factor.
Bottom line: Choose the Campion 580 BR 2009 if your priority is putting more people on the water — it handles 8 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Campion Allante 535i 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
