The Campion Explorer 552i SC 2010 vs Campion LS 645i BR 2005 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 Explorer 552i SC 2010 at 20,8 ft versus Campion LS 645i BR 2005 at 21,0 ft. Weight tells a clearer story for trailering families: the Campion Explorer 552i SC 2010 tips the scales at 3 171 lbs — 3 134 lbs more than the Campion LS 645i BR 2005 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.

The power gap is worth calling out. Rated to 320 hp, the Campion LS 645i BR 2005 has a 95-hp advantage over the Campion Explorer 552i SC 2010's 225-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Campion LS 645i BR 2005 carries 51 gallons versus 47 gallons in the Campion Explorer 552i SC 2010. 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 Explorer 552i SC 2010 is rated for 7 passengers, while the Campion LS 645i BR 2005 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Explorer 552i SC 2010 could be the deciding factor.
