The Campion S 485 CD 2007 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 S 485 CD 2007 at 16,0 ft versus Campion S 505 BR OB 2005 at 16,0 ft. Weight tells a clearer story for trailering families: the Campion S 505 BR OB 2005 tips the scales at 1 280 lbs - 340 lbs less than the Campion S 485 CD 2007 at 940 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 125 hp, the Campion S 505 BR OB 2005 has a 35-hp advantage over the Campion S 485 CD 2007'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 505 BR OB 2005 carries 19 gallons versus 13 gallons in the Campion S 485 CD 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 4 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 505 BR OB 2005 comes in at 10 lbs per hp versus 10 lbs per hp for the Campion S 485 CD 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.
