The Champion Boats 203 CX 2006 vs Champion Boats 220 Bay Champ 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 - Champion Boats 203 CX 2006 at 20,0 ft versus Champion Boats 220 Bay Champ 2007 at 21,0 ft. Weight tells a clearer story for trailering families: the Champion Boats 220 Bay Champ 2007 tips the scales at 1 900 lbs - 350 lbs less than the Champion Boats 203 CX 2006 at 1 550 lbs.

The power gap is worth calling out. Rated to 225 hp, the Champion Boats 220 Bay Champ 2007 has a 25-hp advantage over the Champion Boats 203 CX 2006's 200-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
