The Contender 33 Tournament 2007 is a modified-V design and the Contender 35 Tournament 2013 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department - Contender 33 Tournament 2007 at 34,0 ft versus Contender 35 Tournament 2013 at 34,8 ft. At 13 500 lbs and 13 500 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 1 050 hp, the Contender 35 Tournament 2013 has a 150-hp advantage over the Contender 33 Tournament 2007's 900-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 400 gal and 400 gal - so range won't be a tiebreaker here.
Both boats are rated for 10 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 35 Tournament 2013 and its 1 050-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Contender 33 Tournament 2007 with its 900-hp rating is the more economical daily driver.
