The Campion S 485 CD OB 2005 vs Campion S 545i BR 2007 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.

Size is the most obvious dividing line here. The Campion S 485 CD OB 2005 measures 16,0 feet overall (2005), giving it roughly 14,0 additional feet of deck space compared to the Campion S 545i BR 2007 at 2,0 feet (2007). Weight tells a clearer story for trailering families: the Campion S 545i BR 2007 tips the scales at 2 886 lbs — 2 792 lbs less than the Campion S 485 CD OB 2005 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 225 hp, the Campion S 545i BR 2007 has a 135-hp advantage over the Campion S 485 CD OB 2005'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 S 545i BR 2007 is rated for 8 passengers, while the Campion S 485 CD 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 S 545i BR 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Campion S 485 CD OB 2005 comes in at 1 lbs per hp versus 13 lbs per hp for the Campion S 545i BR 2007. 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.
