The Campion S 505 CD 2007 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 505 CD 2007 measures 16,0 feet overall (2007), 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 — 2 758 lbs less than the Campion S 505 CD 2007 at 128 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 100-hp advantage over the Campion S 505 CD 2007's 125-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 545i BR 2007 carries 29 gallons versus 24 gallons in the Campion S 505 CD 2007. 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 545i BR 2007 is rated for 8 passengers, while the Campion S 505 CD 2007 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 545i BR 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Campion S 505 CD 2007 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.
