Both the Checkmate ZT 275 2010 and the Checkmate ZT 280 2009 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 ZT 275 2010 at 27,3 ft versus Checkmate ZT 280 2009 at 28,0 ft. Weight tells a clearer story for trailering families: the Checkmate ZT 280 2009 tips the scales at 4 900 lbs - 800 lbs less than the Checkmate ZT 275 2010 at 4 100 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 525 hp, the Checkmate ZT 275 2010 has a 100-hp advantage over the Checkmate ZT 280 2009's 425-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Checkmate ZT 275 2010 carries 80 gallons versus 75 gallons in the Checkmate ZT 280 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
The Checkmate ZT 275 2010 is rated for up to 8 people. Passenger data for the Checkmate ZT 280 2009 wasn't available.
Bottom line: Performance buyers should lean toward the Checkmate ZT 275 2010 and its 525-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Checkmate ZT 280 2009 with its 425-hp rating is the more economical daily driver.
