Both the Contender 28 Sport 2013 and the Contender 28 Tournament 2011 are deep-V designs, both built in fibreglass, 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 - Contender 28 Sport 2013 at 28,0 ft versus Contender 28 Tournament 2011 at 28,0 ft. At 4 700 lbs and 4 700 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 600 hp, the Contender 28 Sport 2013 has a 100-hp advantage over the Contender 28 Tournament 2011's 500-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 185 gal and 185 gal - so range won't be a tiebreaker here.
Both boats are rated for 8 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 Contender 28 Sport 2013 and its 600-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Contender 28 Tournament 2011 with its 500-hp rating is the more economical daily driver.
