The Campion LS 645i BR 2006 vs Campion LS 705i SC 2008 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 705i SC 2008 measures 26,0 feet overall (2008), giving it roughly 5,0 additional feet of deck space compared to the Campion LS 645i BR 2006 at 21,0 feet (2006). Weight tells a clearer story for trailering families: the Campion LS 705i SC 2008 tips the scales at 455 lbs — 418 lbs less 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 LS 645i BR 2006 and 320 hp for the Campion LS 705i SC 2008. 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 705i SC 2008 carries 69 gallons versus 51 gallons in the Campion LS 645i BR 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 9 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Campion LS 705i SC 2008 at 26,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Campion LS 645i BR 2006 at 21,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
