Both the Champion Boats 20 Sea Champ 2006 and the Champion Boats 220 Bay 2009 are modified-V designs, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department - Champion Boats 20 Sea Champ 2006 at 20,0 ft versus Champion Boats 220 Bay 2009 at 21,5 ft. Weight tells a clearer story for trailering families: the Champion Boats 220 Bay 2009 tips the scales at 2 200 lbs - 400 lbs less than the Champion Boats 20 Sea Champ 2006 at 1 800 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 225 hp, the Champion Boats 220 Bay 2009 has a 110-hp advantage over the Champion Boats 20 Sea Champ 2006's 115-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 52 gal and 54 gal - so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Champion Boats 220 Bay 2009 is rated for 7 passengers, while the Champion Boats 20 Sea Champ 2006 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Champion Boats 220 Bay 2009 could be the deciding factor.
