When two boats share the same hull type — in this case both the Checkmate Convincor 2800 OBX 2013 and the Checkmate ZT 350 2011 are deep vee designs with fiberglass construction — 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 ZT 350 2011 measures 34,4 feet overall (2011), giving it roughly 6,5 additional feet of deck space compared to the Checkmate Convincor 2800 OBX 2013 at 27,9 feet (2013). At 43 lbs and 8 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.
For family outings this is probably the sharpest distinction between the two. The Checkmate ZT 350 2011 is rated for 10 passengers, while the Checkmate Convincor 2800 OBX 2013 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Checkmate ZT 350 2011 could be the deciding factor.
Bottom line: Choose the Checkmate ZT 350 2011 if your priority is putting more people on the water — it handles 10 passengers and at 34,4 ft it has the deck room to back that rating up comfortably. The Checkmate Convincor 2800 OBX 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
