The Campion Allante 595i SC 2013 vs Campion LS 645i SC 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.
On paper these two are close siblings in the size department — Campion Allante 595i SC 2013 at 21,5 ft versus Campion LS 645i SC 2007 at 23,0 ft. Weight tells a clearer story for trailering families: the Campion LS 645i SC 2007 tips the scales at 4 037 lbs — 4 003 lbs less than the Campion Allante 595i SC 2013 at 34 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 Allante 595i SC 2013 and 320 hp for the Campion LS 645i SC 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 SC 2007 carries 56 gallons versus 47 gallons in the Campion Allante 595i SC 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion LS 645i SC 2007 could be the deciding factor.
Bottom line: Choose the Campion LS 645i SC 2007 if your priority is putting more people on the water — it handles 9 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Campion Allante 595i SC 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
