When two boats share the same hull type — in this case both the Pro-Lite 20 Flats 2009 and the Pro-Lite 21CC 2010 are modified 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 Pro-Lite 21CC 2010 measures 21,7 feet overall (2010), giving it roughly 19,7 additional feet of deck space compared to the Pro-Lite 20 Flats 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Pro-Lite 20 Flats 2009 tips the scales at 1 819 lbs — 1 792 lbs more than the Pro-Lite 21CC 2010 at 27 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.

Both boats share a closely matched power ceiling — 140 hp for the Pro-Lite 20 Flats 2009 and 150 hp for the Pro-Lite 21CC 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 4 gal and 7 gal — so range won't be a tiebreaker here.

Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
