When two boats share the same hull type — in this case both the Checkmate Pulsare 1600 BR 2009 and the Checkmate Pulsare 2100 BR 2013 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 Pulsare 2100 BR 2013 measures 21,0 feet overall (2013), giving it roughly 5,0 additional feet of deck space compared to the Checkmate Pulsare 1600 BR 2009 at 16,0 feet (2009). Weight tells a clearer story for trailering families: the Checkmate Pulsare 2100 BR 2013 tips the scales at 1 375 lbs — 1 290 lbs less than the Checkmate Pulsare 1600 BR 2009 at 85 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 power gap is worth calling out. Rated to 300 hp, the Checkmate Pulsare 2100 BR 2013 has a 175-hp advantage over the Checkmate Pulsare 1600 BR 2009's 125-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Checkmate Pulsare 2100 BR 2013 carries 38 gallons versus 12 gallons in the Checkmate Pulsare 1600 BR 2009. 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 Pulsare 2100 BR 2013 is rated for 6 passengers, while the Checkmate Pulsare 1600 BR 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Checkmate Pulsare 2100 BR 2013 could be the deciding factor.
