The Campion Allante 505i 2012 vs Campion S 505 BR OB 2005 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 Allante 505i 2012 at 17,1 ft versus Campion S 505 BR OB 2005 at 16,0 ft. At 128 lbs and 128 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 125 hp for the Campion Allante 505i 2012 and 125 hp for the Campion S 505 BR OB 2005. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Campion Allante 505i 2012 carries 24 gallons versus 19 gallons in the Campion S 505 BR OB 2005. 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 505i 2012 is rated for 6 passengers, while the Campion S 505 BR OB 2005 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Allante 505i 2012 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Campion S 505 BR OB 2005 comes in at 1 lbs per hp versus 1 lbs per hp for the Campion Allante 505i 2012. 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.
