When two boats share the same hull type — in this case both the Contender 25 Sport 2009 and the Contender 35 Side 2013 are deep vee designs with fiberglass construction — 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?
Size is the most obvious dividing line here. The Contender 35 Side 2013 measures 35,2 feet overall (2013), giving it roughly 7,2 additional feet of deck space compared to the Contender 25 Sport 2009 at 28,0 feet (2009). At 47 lbs and 75 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 750 hp, the Contender 35 Side 2013 has a 250-hp advantage over the Contender 25 Sport 2009'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 2009 carries 185 gallons versus 34 gallons in the Contender 35 Side 2013. 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 35 Side 2013 is rated for 10 passengers, while the Contender 25 Sport 2009 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Contender 35 Side 2013 could be the deciding factor.
Bottom line: Choose the Contender 35 Side 2013 if your priority is putting more people on the water — it handles 10 passengers and at 35,2 ft it has the deck room to back that rating up comfortably. The Contender 25 Sport 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
