The Campion Allante 485ob 2013 vs Campion S 505i SS 2006 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 485ob 2013 at 16,1 ft versus Campion S 505i SS 2006 at 16,0 ft. Weight tells a clearer story for trailering families: the Campion S 505i SS 2006 tips the scales at 1 974 lbs — 1 880 lbs less than the Campion Allante 485ob 2013 at 94 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 135 hp, the Campion S 505i SS 2006 has a 45-hp advantage over the Campion Allante 485ob 2013's 90-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 S 505i SS 2006 carries 19 gallons versus 13 gallons in the Campion Allante 485ob 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 S 505i SS 2006 is rated for 6 passengers, while the Campion Allante 485ob 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion S 505i SS 2006 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Campion Allante 485ob 2013 comes in at 1 lbs per hp versus 15 lbs per hp for the Campion S 505i SS 2006. 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.
