Both the Champion Boats 198 Elite 2006 and the Champion Boats 210 Elite 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 198 Elite 2006 at 19,0 ft versus Champion Boats 210 Elite 2009 at 20,8 ft. Weight tells a clearer story for trailering families: the Champion Boats 210 Elite 2009 tips the scales at 2 100 lbs - 450 lbs less than the Champion Boats 198 Elite 2006 at 1 650 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 300 hp, the Champion Boats 210 Elite 2009 has a 125-hp advantage over the Champion Boats 198 Elite 2006's 175-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 50 gal - so range won't be a tiebreaker here.
Both boats are rated for 5 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: Performance buyers should lean toward the Champion Boats 210 Elite 2009 and its 300-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Champion Boats 198 Elite 2006 with its 175-hp rating is the more economical daily driver.
