The Campion Allante A18 OB BR 2022 vs Campion S 485 CD 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 A18 OB BR 2022 at 18,0 ft versus Campion S 485 CD 2006 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 CD 2006 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 CD 2006's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Campion Allante A18 OB BR 2022 is rated for 5 passengers, while the Campion S 485 CD 2006 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 A18 OB BR 2022 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Campion S 485 CD 2006 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.
Bottom line: Choose the Campion Allante A18 OB BR 2022 if your priority is putting more people on the water — it handles 5 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Campion S 485 CD 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
