Both the Checkmate Convincor 270 2009 and the Checkmate ZT 260 2012 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 - Checkmate Convincor 270 2009 at 27,0 ft versus Checkmate ZT 260 2012 at 26,1 ft. At 4 000 lbs and 4 000 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.
Both boats share a closely matched power ceiling - 425 hp for the Checkmate Convincor 270 2009 and 425 hp for the Checkmate ZT 260 2012. 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. Both carry nearly identical fuel loads - 75 gal and 75 gal - so range won't be a tiebreaker here.
Bottom line: The Checkmate Convincor 270 2009 and Checkmate ZT 260 2012 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
