When two boats share the same hull type — in this case both the Checkmate Convincor 300 2011 and the Checkmate SFX 250 2010 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 300 2011 measures 29,7 feet overall (2011), giving it roughly 4,7 additional feet of deck space compared to the Checkmate SFX 250 2010 at 25,0 feet (2010). At 53 lbs and 4 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.
The power gap is worth calling out. Rated to 425 hp, the Checkmate Convincor 300 2011 has a 250-hp advantage over the Checkmate SFX 250 2010's 175-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 13 gal and 14 gal — so range won't be a tiebreaker here.
Bottom line: The Checkmate Convincor 300 2011 at 29,7 ft is the right call if deck space, comfort, and entertaining are top of your list. The Checkmate SFX 250 2010 at 25,0 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.
