Matching a modified vee Contender 25 Sport 2007 against a deep vee Contender 31 Tournament 2009 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Contender 31 Tournament 2009 measures 32,6 feet overall (2009), giving it roughly 4,6 additional feet of deck space compared to the Contender 25 Sport 2007 at 28,0 feet (2007). Weight tells a clearer story for trailering families: the Contender 31 Tournament 2009 tips the scales at 1 156 lbs — 1 109 lbs less than the Contender 25 Sport 2007 at 47 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 700 hp, the Contender 31 Tournament 2009 has a 200-hp advantage over the Contender 25 Sport 2007's 500-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Contender 25 Sport 2007 carries 185 gallons versus 31 gallons in the Contender 31 Tournament 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Contender 31 Tournament 2009 is rated for 9 passengers, while the Contender 25 Sport 2007 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Contender 31 Tournament 2009 could be the deciding factor.
Bottom line: Choose the Contender 31 Tournament 2009 if your priority is putting more people on the water — it handles 9 passengers and at 32,6 ft it has the deck room to back that rating up comfortably. The Contender 25 Sport 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
