When two boats share the same hull type — in this case both the Sundance B20CCR 2010 and the Sundance F19FLX 2009 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?
On paper these two are close siblings in the size department — Sundance B20CCR 2010 at 19,8 ft versus Sundance F19FLX 2009 at 18,8 ft. Weight tells a clearer story for trailering families: the Sundance B20CCR 2010 tips the scales at 1 525 lbs — 420 lbs more than the Sundance F19FLX 2009 at 1 105 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 — 90 hp for the Sundance B20CCR 2010 and 90 hp for the Sundance F19FLX 2009. 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. Fuel capacity breaks the other way: the Sundance B20CCR 2010 carries 33 gallons versus 24 gallons in the Sundance F19FLX 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 Sundance B20CCR 2010 is rated for 8 passengers, while the Sundance F19FLX 2009 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance B20CCR 2010 could be the deciding factor.
Bottom line: Choose the Sundance B20CCR 2010 if your priority is putting more people on the water — it handles 8 passengers and at 19,8 ft it has the deck room to back that rating up comfortably. The Sundance F19FLX 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
