The Campion 582 CC 2005 vs Campion S 505 O/B BR 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 582 CC 2005 at 19,0 ft versus Campion S 505 O/B BR 2006 at 16,0 ft. Weight tells a clearer story for trailering families: the Campion 582 CC 2005 tips the scales at 1 920 lbs - 640 lbs more than the Campion S 505 O/B BR 2006 at 1 280 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 150 hp, the Campion 582 CC 2005 has a 25-hp advantage over the Campion S 505 O/B BR 2006'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 582 CC 2005 carries 53 gallons versus 19 gallons in the Campion S 505 O/B BR 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 S 505 O/B BR 2006 is rated for 6 passengers, while the Campion 582 CC 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 505 O/B BR 2006 could be the deciding factor.
Bottom line: Choose the Campion S 505 O/B BR 2006 if your priority is putting more people on the water - it handles 6 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Campion 582 CC 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
