When two boats share the same hull type — in this case both the Checkmate Convincor 2800 OBX 2011 and the Checkmate Pulsare 2100 2009 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 Convincor 2800 OBX 2011 measures 27,9 feet overall (2011), giving it roughly 6,9 additional feet of deck space compared to the Checkmate Pulsare 2100 2009 at 21,0 feet (2009). Weight tells a clearer story for trailering families: the Checkmate Pulsare 2100 2009 tips the scales at 1 375 lbs — 1 332 lbs less than the Checkmate Convincor 2800 OBX 2011 at 43 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 Pulsare 2100 2009 tops out at 300 hp. Engine specs for the Checkmate Convincor 2800 OBX 2011 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Checkmate Pulsare 2100 2009 carries 32 gallons versus 13 gallons in the Checkmate Convincor 2800 OBX 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Checkmate Convincor 2800 OBX 2011 is rated for 8 passengers, while the Checkmate Pulsare 2100 2009 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Checkmate Convincor 2800 OBX 2011 could be the deciding factor.
