The Campion 552i SC 2007 vs Campion S 505i SS 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 552i SC 2007 at 19,0 ft versus Campion S 505i SS 2006 at 16,0 ft. Weight tells a clearer story for trailering families: the Campion 552i SC 2007 tips the scales at 3 171 lbs — 1 197 lbs more than the Campion S 505i SS 2006 at 1 974 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 552i SC 2007 has a 90-hp advantage over the Campion S 505i SS 2006's 135-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 552i SC 2007 carries 53 gallons versus 19 gallons in the Campion S 505i SS 2006. 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 552i SC 2007 is rated for 7 passengers, while the Campion S 505i SS 2006 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion 552i SC 2007 could be the deciding factor.
Bottom line: Choose the Campion 552i SC 2007 if your priority is putting more people on the water — it handles 7 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Campion S 505i SS 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
