The Champion Boats 21 Bay Champ 2007 vs Champion Boats 21 SX 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.
Size is the most obvious dividing line here. The Champion Boats 21 Bay Champ 2007 measures 21,0 feet overall (2007), giving it roughly 19,0 additional feet of deck space compared to the Champion Boats 21 SX 2007 at 2,0 feet (2007). Weight tells a clearer story for trailering families: the Champion Boats 21 Bay Champ 2007 tips the scales at 185 lbs — 163 lbs more than the Champion Boats 21 SX 2007 at 22 lbs.

The power gap is worth calling out. Rated to 300 hp, the Champion Boats 21 SX 2007 has a 50-hp advantage over the Champion Boats 21 Bay Champ 2007's 250-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.

The Champion Boats 21 SX 2007 at 2,0 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.
