Both the Checkmate Convincor 2800 OBX 2009 and the Checkmate ZT 230 BR 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?
Size is the most obvious dividing line here. The Checkmate Convincor 2800 OBX 2009 measures 27,0 feet overall (2009), giving it roughly 4,3 additional feet of deck space compared to the Checkmate ZT 230 BR 2013 at 22,8 feet (2013). Weight tells a clearer story for trailering families: the Checkmate Convincor 2800 OBX 2009 tips the scales at 4 300 lbs - 1 400 lbs more than the Checkmate ZT 230 BR 2013 at 2 900 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 2800 OBX 2009 is rated for up to 8 people. Passenger data for the Checkmate ZT 230 BR 2013 wasn't available.
Bottom line: The Checkmate Convincor 2800 OBX 2009 at 27,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Checkmate ZT 230 BR 2013 at 22,8 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
