The Campion 545i SS 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 545i SS 2005 measures 18,0 feet overall (2005), giving it roughly 16,0 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 — 2 862 lbs less than the Campion 545i SS 2005 at 24 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 250 hp, the Campion 545i SS 2005 has a 25-hp advantage over the Campion S 545i BR 2007's 225-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 29 gal and 29 gal — so range won't be a tiebreaker here.

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 545i SS 2005 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 545i SS 2005 comes in at 0 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.
