The Contender 21 Open 2013 vs Contender Center Console 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
Both boats share a closely matched power ceiling - 300 hp for the Contender 21 Open 2013 and 300 hp for the Contender Center Console 2006. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Contender Center Console 2006 carries 400 gallons versus 90 gallons in the Contender 21 Open 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 Center Console 2006 is rated for 10 passengers, while the Contender 21 Open 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Contender Center Console 2006 could be the deciding factor.
Bottom line: Choose the Contender Center Console 2006 if your priority is putting more people on the water - it handles 10 passengers and at 33,0 ft it has the deck room to back that rating up comfortably. The Contender 21 Open 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
