Both the Checkmate Convincor 300 2010 and the Checkmate ZT 280 2013 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 300 2010 at 29,7 ft versus Checkmate ZT 280 2013 at 28,1 ft. Weight tells a clearer story for trailering families: the Checkmate Convincor 300 2010 tips the scales at 5 300 lbs - 400 lbs more than the Checkmate ZT 280 2013 at 4 900 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 Checkmate Convincor 300 2010 carries a rated maximum of 425 hp. Engine data for the Checkmate ZT 280 2013 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Checkmate Convincor 300 2010 carries 130 gallons versus 75 gallons in the Checkmate ZT 280 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Bottom line: The Checkmate Convincor 300 2010 and Checkmate ZT 280 2013 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.
