The Campion 580 O/B BR 2006 vs Campion 650i 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 580 O/B BR 2006 at 18,0 ft versus Campion 650i BR 2006 at 21,0 ft. Weight tells a clearer story for trailering families: the Campion 580 O/B BR 2006 tips the scales at 202 lbs — 165 lbs more than the Campion 650i BR 2006 at 37 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 375 hp, the Campion 650i BR 2006 has a 175-hp advantage over the Campion 580 O/B BR 2006's 200-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 650i BR 2006 carries 51 gallons versus 28 gallons in the Campion 580 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 580 O/B BR 2006 is rated for 8 passengers, while the Campion 650i BR 2006 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion 580 O/B BR 2006 could be the deciding factor.
Bottom line: Choose the Campion 580 O/B BR 2006 if your priority is putting more people on the water — it handles 8 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Campion 650i BR 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
