The Campion 580 BR OB 2005 vs Campion Allante 535i 2013 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Campion 580 BR OB 2005 at 18,0 ft versus Campion Allante 535i 2013 at 17,8 ft. Weight tells a clearer story for trailering families: the Campion 580 BR OB 2005 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 OB 2005 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 OB 2005 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 Allante 535i 2013 is rated for 7 passengers, while the Campion 580 BR OB 2005 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Allante 535i 2013 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Campion Allante 535i 2013 comes in at 0 lbs per hp versus 1 lbs per hp for the Campion 580 BR OB 2005. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
