Both the Checkmate Convincor 2800 OBX 2012 and the Checkmate ZT 260 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 2800 OBX 2012 at 27,9 ft versus Checkmate ZT 260 2013 at 26,1 ft. Weight tells a clearer story for trailering families: the Checkmate Convincor 2800 OBX 2012 tips the scales at 4 300 lbs - 300 lbs more than the Checkmate ZT 260 2013 at 4 000 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.
For family outings this is probably the sharpest distinction between the two. The Checkmate Convincor 2800 OBX 2012 is rated for 8 passengers, while the Checkmate ZT 260 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Checkmate Convincor 2800 OBX 2012 could be the deciding factor.
Bottom line: Choose the Checkmate Convincor 2800 OBX 2012 if your priority is putting more people on the water - it handles 8 passengers and at 27,9 ft it has the deck room to back that rating up comfortably. The Checkmate ZT 260 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
