The Campion 550i BR 2006 vs Campion LS 645i 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 LS 645i BR 2007 measures 23,0 feet overall (2007), giving it roughly 5,0 additional feet of deck space compared to the Campion 550i BR 2006 at 18,0 feet (2006). Weight tells a clearer story for trailering families: the Campion LS 645i BR 2007 tips the scales at 4 037 lbs — 4 013 lbs less than the Campion 550i BR 2006 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.

Both boats share a closely matched power ceiling — 320 hp for the Campion 550i BR 2006 and 320 hp for the Campion LS 645i BR 2007. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Campion LS 645i BR 2007 carries 56 gallons versus 29 gallons in the Campion 550i 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 LS 645i BR 2007 is rated for 9 passengers, while the Campion 550i 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 LS 645i BR 2007 could be the deciding factor.
