The Campion Chase 550i 2012 vs Campion LS 645i 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 Chase 550i 2012 at 20,2 ft versus Campion LS 645i BR 2006 at 21,0 ft. Weight tells a clearer story for trailering families: the Campion Chase 550i 2012 tips the scales at 2 886 lbs — 2 849 lbs more than the Campion LS 645i 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.
Both boats share a closely matched power ceiling — 320 hp for the Campion Chase 550i 2012 and 320 hp for the Campion LS 645i BR 2006. 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 2006 carries 51 gallons versus 29 gallons in the Campion Chase 550i 2012. 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 2006 is rated for 9 passengers, while the Campion Chase 550i 2012 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 2006 could be the deciding factor.
Bottom line: Choose the Campion LS 645i BR 2006 if your priority is putting more people on the water — it handles 9 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Campion Chase 550i 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
