The Sundance B20 CX 2006 vs Sundance FX19 Vapor 2011 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — Sundance B20 CX 2006 at 19,0 ft versus Sundance FX19 Vapor 2011 at 19,1 ft. Weight tells a clearer story for trailering families: the Sundance B20 CX 2006 tips the scales at 1 595 lbs — 1 493 lbs more than the Sundance FX19 Vapor 2011 at 102 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 — 130 hp for the Sundance B20 CX 2006 and 150 hp for the Sundance FX19 Vapor 2011. 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 — 33 gal and 31 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Sundance B20 CX 2006 is rated for 11 passengers, while the Sundance FX19 Vapor 2011 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance B20 CX 2006 could be the deciding factor.
Bottom line: Choose the Sundance B20 CX 2006 if your priority is putting more people on the water — it handles 11 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Sundance FX19 Vapor 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
