The Campion 622i Sedan 2008 vs Campion LS 645i SC 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 622i Sedan 2008 at 23,0 ft versus Campion LS 645i SC 2005 at 21,0 ft. Weight tells a clearer story for trailering families: the Campion 622i Sedan 2008 tips the scales at 4 392 lbs - 692 lbs more than the Campion LS 645i SC 2005 at 3 700 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 SC 2005 has a 95-hp advantage over the Campion 622i Sedan 2008's 225-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 50 gal and 51 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Campion 622i Sedan 2008 is rated for 9 passengers, while the Campion LS 645i SC 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 622i Sedan 2008 could be the deciding factor.
Bottom line: Choose the Campion 622i Sedan 2008 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 LS 645i SC 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
