The Campion Allante A18 OB BR 2022 vs Campion S 485 BR 2008 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 A18 OB BR 2022 at 18,0 ft versus Campion S 485 BR 2008 at 16,0 ft. Weight tells a clearer story for trailering families: the Campion Allante A18 OB BR 2022 tips the scales at 1 955 lbs — 1 861 lbs more than the Campion S 485 BR 2008 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 150 hp, the Campion Allante A18 OB BR 2022 has a 60-hp advantage over the Campion S 485 BR 2008'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 Allante A18 OB BR 2022 carries 25 gallons versus 13 gallons in the Campion S 485 BR 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 5 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Campion S 485 BR 2008 comes in at 1 lbs per hp versus 13 lbs per hp for the Campion Allante A18 OB BR 2022. 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.
