The Campion 550i BR 2009 vs Campion 580 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 580 BR 2007 measures 19,0 feet overall (2007), giving it roughly 17,0 additional feet of deck space compared to the Campion 550i BR 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Campion 550i BR 2009 tips the scales at 2 886 lbs — 2 684 lbs more than the Campion 580 BR 2007 at 202 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 320 hp, the Campion 550i BR 2009 has a 120-hp advantage over the Campion 580 BR 2007's 200-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 28 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Campion 580 BR 2007 is rated for 8 passengers, while the Campion 550i BR 2009 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 BR 2007 could be the deciding factor.
Bottom line: Choose the Campion 580 BR 2007 if your priority is putting more people on the water — it handles 8 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Campion 550i BR 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
